GE and Carbon Trust team up to back low-carbon investment

GE and Carbon Trust team up to back low-carbon investment


US giant GE and the UK government-backed Carbon Trust are teaming up to launch a Europe-wide low-carbon incubation fund.
Europe has seen a 40% decrease in its share of clean energy investment since 2007, according to a 2011 Bloomberg New Energy Finance report, and one in two businesses see the UK as a ‘challenging environment’ for innovation.
The new partnership, which is an extension of GE’s successful $200 million ecomagination challenge, aims to support start-ups in clean technology.
Initially, the partnership has set up a $5 million business incubation fund targeted at new low carbon technologies for infrastructure applications.
GE and the Carbon Trust will identify and assess early-stage companies, then incubate and invest in the most promising.
“Clean tech has the capacity to be a strong growth driver for Europe given its strong research capability and track record in this area. However, there is increasing evidence that other parts of the world are catching up and overtaking the region,” says Carbon Trust chief executive Tom Delay.
Delay adds that incubation funds such as this one are particularly important right now as banks reign in their lending.
“During a downturn, supporting these businesses becomes doubly important: research studies show that such high growth businesses account for a disproportionate amount of job growth,” he says

Low Voltage Halo lamps to be banned from next year!

Low-voltage halogen lamps are to be banned from next year under draft legislation drawn up by the European Commission, Lux magazine can reveal
12V MR16 lamps are the workhorses of retail, commercial and, increasingly, residential lighting and millions are sold every year in the EU.
But under Ecodesign legislation, ‘poor performing’ versions are to be phased out from next year.
Better-performing versions, such as those with infra-red coatings, will follow by 2016.
The law sets out a series of minimum performance measures, including lifetime, output in a 90-degree cone and ef ficiency, which will effectively mean that low quality lamps – often Far Eastern imports – will be excluded from sale in the European Union from 2013.
The phase-out is part of the Ecodesign legislation, which led to the phase-out of incandescent lamps in recent years.
Paul Hodson of the directorate-general for energy is currently consulting with peers before publication of the final draft.
Lamp makers are said to be concerned with the new performance metrics, the timescales of the ban and supplies of IRC capsules.

House of Commons European Scrutiny Committee - The future of lighting


16 Development of innovative lighting technologies

(33572) 18853/11
COM(11) 889
Commission Green Paper: Lighting the Future — Accelerating the Deployment of Innovative Lighting Technologies

Legal base
Document originated 15 December 2011
Deposited in Parliament 22 December 2011
Department Environment, Food and Rural Affairs
Basis of consideration EM of 14 January 2012
Previous Committee Report None, but see footnotes
Discussion in Council No date set
Committee's assessment Politically important
Committee's decision Cleared
Background
16.1 The Commission says that lighting accounts for 14% of EU electricity consumption, and that, as incandescent lamps are being phased out, new energy efficient and eco-friendly technologies are starting to replace them. It identifies solid state lighting (SSL) — based on semi-conducting materials, and comprising light emitting diode (LED) and organic light emitting diode (OLED) — as the most innovative of these, and it notes that, having first been introduced in traffic and car lights, this is already widely used for lighting displays, and is now entering the general lighting market.

16.2 It goes on to suggest that wide-scale uptake could contribute substantially to the sustainable growth objectives of the Europe 2020 strategy (and in particular the target of increasing energy efficiency in 2020 by 20%), but that larger uptake of current SSL products faces a number of challenges, in that they are expensive, unfamiliar to users, subject to rapid innovation, and hampered by a lack of standards. It also says that, although the EU has a wide range of policy instruments to stimulate the uptake of such technologies, it is necessary to consider whether new or additional measures are needed in relation to both the supply and demand sides (and, if so, what).

The current document

16.3 The Commission has therefore brought forward this Green Paper as part of the Digital Agenda for Europe flagship initiative under the Europe 2020 strategy, with the aim of setting out the key issues to be addressed in a European strategy to accelerate the deployment of high-quality SSL for general lighting. It also says that the document has important links to several other flagship initiatives, including Innovation and Industrial Policy, the Energy Efficiency Plan for 2011 the new Horizon 2020 framework for research and innovation, the Thematic Strategy on the Prevention and Recycling of Waste, the Key Enabling Technologies Initiative, and Regional Policy Funds.

16.4 The Commission says that SLL is a breakthrough in general lighting in relation to energy efficiency (as it will in the next few years outpace existing technology, allowing significant energy savings, and reduce carbon dioxide emissions); lighting quality and visual comfort (as it offers lighting which has a long lifetime, does not contain mercury and has easily controlled colour and intensity); design and aesthetics; and innovation and business opportunities. It adds that intensive manufacturing and research activities around the world should further improve SSL performance, but it notes that, with market penetration in the EU being currently very low, it faces a challenge in removing barriers to the delivery of SSL's large potential for domestic use and other applications, whilst helping the European industry to remain at the forefront of global competition.

MEASURES TO INFLUENCE DEMAND

16.5 It suggests that the issues to be addressed so far as consumers and professional users are concerned include:
— Low quality LED products
Many such products emit low-quality cold white light, and life-times are often much shorter than claimed. Consequently, minimum quality requirements are a key factor, and, although Member States are responsible for monitoring the performance and safety of products sold holding the CE marking label, the Commission believes that an efficient market surveillance scheme is a pre-requisite.
— High initial purchase costs
The Commission notes that, although rapid advances in technology have led SSL costs to drop by 30% a year, LED lamps will continue in the foreseeable future to be more expensive than other existing technologies.
— Lack of user awareness
The Commission says that users do not yet consider SSL as an important low-carbon technology, and are unable to weigh up its costs against its advantages.
— Insufficient or poor product information
The Commission says that the necessary technical properties for consumers to choose an appropriate product are often not provided or are poorly explained.
— Concerns for biological safety
The Commission says that, although an expert study has not identified any evidence that the "blue spectral component" of LED light presents a health hazard, this remains a concern of many consumers.
— Rapid technology obsolescence
The Commission says that users hesitate to use SSL because of continuing price drops and speedy increases in efficacy, and that safety gaps exist in existing technology standardisation.
It also says that large SSL deployment in cities is hindered by high upfront costs, particularly at a time of financial stringency, and that, in the case of private buildings, by the differing interests of landlords and tenants.
16.6 The Commission then identifies a number of initiatives to increase SSL uptake. It notes that a broad range of voluntary and mandatory EU instruments already exist which are regularly reviewed to reflect technological progress and new EU policy, and that changes to reflect recent developments are currently being considered a number of areas, such as the Eco-design and Energy Labelling Directives, the Ecolabel Regulation, the Low Voltage Directive, and the new EU Green Public Procurement criteria. In addition, it notes that a voluntary initiative (GreenLight) encourages non-residential users to install energy-efficient lighting technologies, whilst the International Energy Agency is addressing the issue of SSL global quality by developing a quality assurances scheme.

16.7 The Commission observes that a number of further measures could nevertheless be taken. In the case of consumers, it suggests that the lighting industry and/or consumer associations could organise awareness campaigns, whilst Member States and the industry can ensure that SSL products conform to EU performance and safety requirements. In particular, it advocates the creation of SSL lead markets. In the case of cities, it notes the role of Green Public Procurement and the existence of financial instruments — such as the European Local Energy Assistance (ELENA) and European Energy Efficiency Fund (EEE-F) — for cities to finance feasibility studies, and that they have the potential to become leading markets for SSL. It says that it is therefore considering inviting representatives from cities and the industry to establish a dedicated Task Force to set out a roadmap, including the introduction of innovative financial schemes; to invite cities to use ELENA and EEE-F, existing structural funds and other financial mechanisms to plan the large scale deployment of SSL; to organise a number of awareness raising events; and to examine the use of mechanisms, such as the new Cohesion Policy, to implement large scale pilot, demonstration and deployment actions.

16.8 In the case of public buildings, the Commission again notes the opportunities presented by Green Public Procurement; the extent to which the proposal for a Directive on Energy Efficiency includes elements which could foster the uptake of SSL; and the that requirement in the Energy Performance of Buildings Directive that all new public buildings should become near-zero energy by 2019 will be extended to all new buildings by 2021. As regards residential buildings, it says there is also a need to put in place financial and other incentives, such as innovative contracting models, for users to buy and install new SSL technologies. It also proposes that public authorities should be invited to promote the wide deployment of SSL technologies when they renovate public buildings, and that Member States should provide incentives to consumers to replace lighting systems in their homes by SSL.

MEASURES TO INFLUENCE SUPPLY

16.9 The Commission notes that the European lighting industry is highly innovative, but is fragmented along its supply chain, and that, alongside a number of large global players, it consists of several thousand SMEs. It adds that, although the industry is well positioned as regards the emerging OLED technology, it is struggling to turn leadership in research and development into business success. At the same time, the Commission points out that the wider deployment of SSL will affect lighting as a business, with retrofit activities expected to dominate the market for the next three to five years, underpinned by the phasing-out of incandescent bulbs, and that there will be an increasing emphasis on intelligent lighting systems and services. Also, the customising of lighting characteristics to specific users' requirements will provide new business opportunities, requiring enhanced cooperation by European manufacturers, with others along the value chain (including wholesalers and retailers, urban planners, architects and lighting designers, manufacturers of electrical components and systems, installers, facility managers, the construction industry, and lighting service companies), and with vertical integration already taking place and expected to continue.

16.10 The Commission believes that the next three to five years will also be pivotal in establishing leading SSL market players, with the European industry being in principle in a strong position. However, it notes that it is already under significant pressure from newly, mainly Asian, competitors, and it has therefore suggested a strategic approach for achieving a competitive SSL industry in Europe. This would include translating ideas into marketable products by focussing on technological research, product development and demonstration, and advanced manufacturing; strengthening the SSL value chain; fostering cooperation between the industry and others in the extended value chain, with the industry taking strategic decisions on the future of SSL marketing in Europe; and securing the supply of scarce raw materials and the recycling of end-of-life SSL products. In addition, it says that the further development of the European industry will depend on standardisation, on access to intellectual property rights and to low cost routes of investment, and on learning and training.

16.11 The Commission then looks at initiatives for strengthening the SSL value chain. It notes the steps taken as regards EU for research and innovation during the period 2007-13, including expenditure under the Seventh Framework Programme on the manufacturing processes for LEDs and OLEDs, materials research, and improving the performance of SSl-based applications; support provided under the Competitiveness and Innovation Programme on raising consumer awareness and supporting Member States in market surveillance activities; and the use of the Structural Funds to enhance the capacity to innovate in SSL. It says it is now considering a number of further actions, including:
  • mandating the European Standard Organisations to develop standards;
  • pilot actions to raise EU-wide awareness of SSL technologies;
  • continuing to fund under the Seventh Framework Programme research on new lighting sources and on novel materials to replace critical raw materials;
  • the creation under Horizon 2020 of a Public Private Partnership in Photonics;
  • giving priority to SSLs as part of regional smart specialisation strategies under the new Cohesion Policy.
16.12 Finally, the Commission looks at the action which industry might take. It suggests that this might include:
  • launching initiatives which extend the scope of business alliances;
  • matching public support to a Photonics PPP with a commitment to invest in Europe;
  • working with consumers to develop new functionalities for lighting applications to encourage faster uptake;
  • working with European Standardisation Organisations to address issues related to SSL, including those relating to safety, environmental aspects, and the measurement of the performance of products and systems;
  • further engaging in assessing the full life cycle impact of SSL products;
  • using all existing mechanisms for launching vocational and lifelong learning and training.
The Government's view
16.13 In his Explanatory Memorandum of 14 January 2012, the Parliamentary Under-Secretary of State at the Department for Environment, Food & Rural Affairs (Lord Taylor of Holbeach) says that the Government broadly welcomes the Green Paper as it is consistent with its own views and work, and will therefore reply to the consultation expressing its general support for the proposals.

16.14 He notes that the Government has a policy of removing inefficient lighting products from the market in favour of energy efficient alternatives, and that it is therefore working to encourage the innovation of ultra efficient lighting, recognising that this has the potential to provide significant carbon dioxide emissions savings over and above those produced by alternatives, such as compact fluorescent lamps (CFLs), whilst offering UK companies the opportunity to take advantage of the growing worldwide demand for energy-efficient lighting.

16.15 He adds that the Government has been focusing in particular on two of the issues identified in the Green Paper — the fact that SSL technology currently has a long pay-back period, and that the wide variation in performance of SSL products currently on the market threatens consumer confidence, delays market acceptance and slows down penetration rates. He says that, to address the first of these points, it has recently run a £1.2m challenge to develop LED lighting to replace conventional incandescent lamps: and, in order to address the second, it is participating in two international collaborations which are pushing the development of SSL technologies. He notes that these initiatives support the work being done on a national level to address the main challenges with SSL technologies, including providing better information to governments and consumers about SSL products, and he believes that the Commission should become more actively engaged in both of them, particularly where work on harmonisation and standard development is envisaged.

Conclusion

16.16 By the standards of many such documents produced by the Commission, this Green Paper provides an interesting and coherent account of recent developments in relation to solid state lighting, and of the measures which the EU can take to promote its uptake. Consequently, whilst we see no need to withhold clearance, we are drawing the document (and the Government's comments on it) to the attention of the House.

All "WHITE" on the night?

Colour Point Consistency & The Binning Process

The colour rendering issue can be resolved by extending the CRI test. Conventional testing (of fluorescent sources and other discharge lamps) uses an 8-colour point reference system to assess colour accuracy. This has been shown to be unreliable for LEDs, which need a 9-point - or possibly even a 15-point system of measurement.
Colour Point Consistency needs to be tightened. This is all about reducing the acceptable tolerances in colour deviation between chips. The MacAdam Ellipse and SDCM (Standard Deviation of Colour Matching) that are used in these kinds of assessments - suffice to say that elements within the LED industry are calling for a maximum of 2-3 SDCM/MacAdam steps, which is described as 'hardly any colour difference visible'

NOTE: Only 1 SDCM/MacAdam step means that there is no colour difference between chips. Greater than 4 SDCM/MacAdam steps is defined as there being a 'colour difference visible'.


What is the Binning Process?
An additional consideration is that the process for producing LEDs cannot accurately reproduce them with identical colour appearances, especially for white LEDs.
To overcome this a process called binning is used, in which the LEDs are sorted into groups of similar colour appearance.
The level of precision required depends upon the application. Basically, the shorter the throw of the light before illuminating a surface or where numerous light sources are in the field of view, the more critical the binning.
Hence, for an application such as wall washing, it’s essential for all the LEDs to match closely to give a consistent appearance.
However, if floodlighting a statue with one or two projectors from an adjacent building the binning process is less important, as individual differences would be less obvious


Binning practices need to be standardised across the industry, especially as we are seeing a burgeoning replacement lamp sector and we can easily imagine LED lamps from one source being installed alongside another.

New emergency lighting standard

The British Standards Institution (BSI) has revised its emergency lighting standard to ensure the safety of building occupants in the event of a sudden loss of normal lighting or fire.

BS 5266-1- Emergency lighting – Part 1: Code of practice for the emergency escape lighting of premises considers the provision of emergency lighting in all types of non-domestic premises – including both new and existing installations.

The revised standard is designed to give confidence to owners of premises, landlords and employers that they are meeting their legal requirements regarding emergency lighting. It also addresses the needs of lighting engineers and electrical contractors whose duty is to protect building occupants from the hazards identified by risk assessments.

Designed by industry for industry, BS 5266-1 incorporates the requirements from a diverse committee including local authorities, trade bodies and professionals from safety, fire and property arenas.
The standard has been rewritten to embrace the Regulatory Reform (Fire Safety) Order 2005 (FSO) which brings all non-domestic premises within the scope of fire safety law. It also places responsibility for emergency lighting on the person who controls the premises.

BSI aims to promote wider understanding of the different types of emergency lighting systems which may be employed, and to give guidance on their correct application within the premises. As well as ensuring safe unobstructed means of escape from the premises at all times, BS 5266-1 specifies the need to make possible the immediate location and operation of fire alarm call points and fire-fighting equipment.

“Building owners, landlords and employers all have a duty of care to building occupants,” said Dan Palmer, Head of Market Development at BSI. “Failure to take appropriate measures to ensure a safe escape in the event of lighting failure can result in fines and prosecution. BSI’s newly revised standard for emergency lighting will help responsible parties mitigate this risk and provide greater assurance over the well being of building occupants.”

Spot replacment v's full re-lamp

There are a variety of reasons to practice group relamping, in which a set of lamps is replaced at a scheduled time, rather than spot relamping, in which lamps are only replaced when they burn out. Most of these reasons apply to fluorescent and high-intensity discharge (HID) lamps rather than incandescents, which have much shorter lifetimes.

• Group relamping requires much less labour per lamp than spot relamping. A worker might take as long as a half hour to retrieve and install a single lamp. If all the materials were on hand for a large number of lamps, a worker could move systematically from fixture to fixture and cut the required time to about 2 minutes per lamp. The process would also be less disruptive, because group relamping is usually done outside working hours.

• Group relamping is easy to schedule and delegate to outside contractors, who have special equipment and training.

• Group relamping provides brighter and more uniform lighting because lamps are replaced before their output has fully depreciated.

  • Direct energy benefits result as the ballast is not powering a blown or old lamp

• Group relamping offers increased control over the replacement lamps, reducing the chances of mixing incompatible lamps—such as those with different color temperatures.

How do LED's Work?

LED’s or light emitting diodes, work on a completely different basis to other light sources. A diode is created when two conductive materials are placed in contact with each other. When electricity is passed through them, the atoms in one of the materials become excited to a higher energy state. The excess energy is then released to the other material making up the diode and in the process light is generated.

LED’s are much more efficient than incandescent lamps. An incandescent lamp will typically waste 98% of the energy used in the form of excess heat. A 100-watt light bulb emits about 1,700 lumens – that’s only 17 lumens per watt. A typical LED will achieve a light output efficiency of 60 – 80 lumens per watt. Outputs greater than 100 lumens per watt have been reported, usually under laboratory or optimal test conditions.

It’s a sobering thought to think that up to 98% of the energy you are using to power your lights could be being wasted in the form of unwanted heat.

LED will typically save 70-85% energy costs which considering inefficient lighting can be up to 60% of your overall utilities costs is not an insignificant amount of money.

LED lamps are low voltage solid-state devices that cannot operate on a standard AC current. Part of the cost of an LED lamp is the internal circuits that are required to allow them to operate on an AC circuit.

LED’s will be damaged by excessive heat.

Heat is an LED’s worst enemy. The majority of LED’s will have heat sinks and cooling fins designed to keep the LED within its temperature design parameters.

Most LED lamps deal with the heat issue in one of two ways. Some LED lamps have multiple arrays of LED’s with built in redundancy. Thus a number of the individual LED’s could fail before light output is impaired. In addition to the ‘safety in numbers approach’, some engineers believe that is easier to dissipate heat through a large number of contact points than through a single point of contact. Thus they believe that a ‘multiple array’ will be more reliable.

Some LED lamps are single ‘high power’ LED units. Here the LED is much larger and as the name suggests, there is only one of them providing the light.

Heat management in LED lamps is absolutely crucial. No amount of ‘go faster’ cooling fins will make up for a poor thermal path. This is why cheaper "alternatives" on the market will fail and give the LED a poor reputation.
Typically LED’s are encapsulated in a transparent resin – the lens. This resin is a poor thermal conductor so the heat must be conducted away from the LED through the backside of the chip – the area that you can’t see.

Weblight joins the Carbon Trust & Siemens green finance deal!!

This major new deal will boost green growth and unlock business investment in the low carbon economy – key to the UK’s recovery. The new dedicated low carbon finance scheme is a first and will enable UK businesses to invest in cost effective energy efficiency equipment or other low carbon technologies, such as new efficient lighting and biomass heating.
 
All businesses will be able to apply for new green growth finance from the scheme from 4 April 2011. Under a Heads of Agreement signed between the two parties Siemens Financial Services Ltd. in the UK (SFS UK) will provide the financial backing and manage the provision of funding and the Carbon Trust will use its expertise in carbon saving from energy efficient technologies to assess the carbon, energy and cost savings of any application. This will enable the financing to pay for itself through energy savings.

Tom Delay, chief executive of the Carbon Trust, commented:
“Driving green growth in the UK is key to our economic recovery. A missing ingredient at present is access to affordable finance to enable business to make green investments. This new major finance facility will improve business competitiveness, cut carbon and boost green growth.”

James Gearey, CEO from Siemens Financial Services Ltd. UK commented:
“We are delighted to be working with the Carbon Trust, their values very much match our own. Siemens has been reporting the performance of its environmental portfolio since 2002, not just the commercial performance, but also the hundreds of millions of tonnes of carbon emission reduction that has been delivered through Siemens technology.

Siemens Financial Services has extensive experience of asset financing and lending to UK business and is particularly successful in the SME sector. This background combined with our ready access to funding means we are well placed to support the scheme and deliver the associated benefits to its future customers.”

Miles Templeman, the Director General of the Institute of Directors, said: “In today’s high energy cost environment improving energy efficiency is a must for all businesses. The new Energy Efficiency Finance scheme could play a significant role in stimulating innovative solutions.”

John Sauven, Executive Director of Greenpeace, welcomed the partnership:
“This green finance deal is exactly the sort of initiative that we need to see happening more frequently in the future. A green growth strategy can only work if it is backed by green finance. Deals like this, alongside the development of a green infrastructure bank, could be a tipping point that the UK economy needs to get out of the current doldrums.”

The Carbon Trust and Siemens Financial Services have also agreed to finance a new commercial venture that will increase the take up of energy efficiency projects. This venture will offer procurement support to businesses wishing to purchase energy efficiency equipment at scale from a network of accredited suppliers and will be launched later this year.

LED - In schools, its proven and its hear to stay.

SCHOOLS in Oxfordshire could soon be slashing their electricity bills with the introduction of new energy saving lights.

Secondary schools could save an average of £20,000 a year and primary schools about £3,000 by using the carbon-reducing tube lights, according to the county council.
John Mason School in Abingdon is now saving about £18,000 a year after installing the lights throughout its buildings in the summer holidays.

The school decided to buy the Light Emitting Diode (LED) filled tubes after a month-long trial in two classrooms organised by Oxfordshire County Council. The lights saved 40 per cent more energy and cash than the old fluorescent tubes.
The school’s business manager Alex Keeble said the lights cost about £80,000, but the school was now saving 40 per cent on its electricity bills.

She said: “Like everyone we are getting increasingly worried about our energy costs, so we have been very impressed with the results.
“The possibility of investing in a scheme that will have a significant impact on our budget and benefit the environment can only be good news for us. Less money on energy also means more money to support the education of our students.”

She added: “Not only have we seen a reduction in costs from the trial period, but the actual illumination has given better working conditions for students and staff.”
Oxfordshire County Council hopes other schools will now consider the lights as part of a wider drive to cut carbon emissions and energy costs across all its buildings.

Darrell Marchand, the council’s energy and environmental manager, said: “Before we recommend a new energy efficient technology to schools we need to know it will perform at the level anticipated.
“To make the experiment fair we compared the two types of light and the results were pretty emphatic.”

Cabinet member for growth and infrastructure Lorraine Lindsay-Gale added: “This has significant implications for the carbon footprint of schools.
“Lighting accounts for about 50 per cent of schools’ electricity needs and LED lighting could have a real impact on the lighting costs for our schools.”

The need for more efficient lighting was identified after a council energy survey at every maintained school in the county over the past four years.

Council spokesman Marcus Mabberley added: “Individual schools hold the money to pay their energy bills, so decisions about installing energy efficient measures would rest with them.”

The IPAD3 will have LED back light!! according to on-line experts

Apple will be implementing a new LED back-light design for iPad 3, report

Posted on 07. Nov, 2011 by in Tablets
Apple iPad 2 teardown LCD panel ifixit
When you take off the front frame on the Apple iPad 2 you get to see the 9.7-inch LCD panel and more. Image: Ifixit
Operating on the assumption that Apple is actively pursing a Retina Display for the next Apple iPad tablet the rumor mill is reporting that Apple will introduce a new LED backlight design with the next iPad tablet. Apperantly the current single LED back-light design used in the 1024×768 resolution iPad 1 and iPad 2 isn’t sufficent for the 2048×1536 resolution display that’s reportedly being used on the next-gen. Apple iPad tablet.
DigiTimes is reporting all of this exclusively through intel gained from unnamed sources at Taiwan-based BLU (back-light unit) makers. According to those sources Apple will be implenting one of two new dual-LED light bar designs; one is a single-bar design that includes two LED chips, another design uses two LED light bars.
The unnamed DigiTimes sources said a dual light bar design is most probable becuase local BLU makers in Taiwan have already solved heat dissipation and battery consumption problems for such a design.
It’s no secret that the next-gen. Apple iPad will need to have a whole new design to satisfy all the rumored features, so really this report by DigiTimes is quite resonable. With the next iPad, the iPad 3 (possible name), keeping the 10 hours of battery life that iPad 1 and iPad 2 have featured will be imperative for Apple. Even though no competitors have been able to touch the iPad 2′s battery life I don’t think Apple will the iPad 3 have bad battery life at any cost.

Rare Earth - why lamp prices are still rising! by GE


What is the issue? 

A shortage of the materials known as ‘Rare Earths’ (RE) on global markets is driving up prices of a whole range of goods, from TV and laptop screens to disc drives and catalytic converters.
Rare Earths are also an essential component of fluorescent lighting products, and the meteoric increase in RE prices has led to a significant rise in manufacturing costs. For an idea of the scale of these rises, if rare earths were coffee, a latte-to-go that cost €1.50 just a few months ago would now cost almost €16! The situation remains volatile and further price increases seem highly likely.
This briefing paper provides a high level overview of the impact that rare earth shortages are having – and will continue to have – on GE Lighting and our products.

What are Rare Earths? 

Rare Earths are a group of 17 elements with unique properties that make them virtually indispensible in the production of a wide range of modern goods.
Neodymium, for instance, is highly magnetic and used in cell phones, loudspeakers, hard drives and catalytic converters. Others are used in camera lenses, electric vehicles, rechargeable batteries, petroleum refining, defense technology and lighting.
Despite the name, many of these elements are not all that rare; the problem is that they are not found in concentrations sufficient to make extraction commercially viable.

What Rare Earths are used in lighting products? 

More than half of the phosphor used in linear fluorescent (LFL) and compact fluorescent (CFL) products is derived from rare earths, and as many as five different rare earths are required to create the white light.

Why have prices risen? 

Two factors have driven the rise in prices. Firstly, there has been a huge growth in consumption driven by mushrooming demand for consumer/electronic goods, and in rare earth-hungry applications such as hybrid/electric vehicles and wind turbines.
And secondly, the world’s major producer, China – currently responsible for around 97% of global output – has been limiting production and imposing quotas on its exports every year.
China’s limits on the export of Rare Earths tends to promote production of materials elsewhere in the world.

What impact has the shortage of Rare Earths had? 

The Rare Earths shortage has had a dramatic impact on world prices.
According to the Financial Times, prices rose by a factor of between three and five between January and May 2011. 
Over the last 12 months, the prices of some Rare Earths – including Terbium and Europium, both used in fluorescent lamp phosphors – have increased by around one thousand per cent, others by even more. 
In June, it was reported that the price of some rare earths had doubled within just two weeks. 
This has lead to stockpiling by some dealers, driving up prices further still.

What’s the current situation? 

Demand for some rare earths will undoubtedly outpace supply for some time to come but many actions are underway to help manage the situation. The United States, the European Union and other governments are working with China to ensure balanced and fair trade policies.

Could this ‘lost’ production be replaced? 

In the short term no; in the medium to long term yes.
Work is underway to open – or in some cases reopen – mines in the USA, Canada, Australia and Vietnam; and advances in recycling technologies could release many thousands of tons of materials currently ‘stored’ in old electronics and other products. In July 2011, Japanese researchers announced the discovery of what appears to be vast deposits of Rare Earths in the mud of the Pacific Ocean. However it would be some years before these would reach world markets.
For the foreseeable future though, the current situation will have a serious and detrimental impact on the availability – and cost – of Rare Earth materials.


How does this specifically affect GE Lighting? 

As a company for whom Rare Earths are an essential component of production, scarcity and rising prices will clearly have an impact, one that has been intensified in the EU27 countries due to energy efficient legislation driving increased use of rare-earth phosphor containing lamps.
However, it should be remembered that this isn’t just a challenge for GE Lighting; it’s a global issue, one that’s having an impact on manufacturers and users of all kinds of goods.


What does the future hold? 

No one can be sure what’s going to happen next. As already mentioned, the situation remains volatile and prices are likely to fluctuate over the coming months and even years. We have therefore taken a number of actions:
We have established teams across the company to help manage this unprecedented supply chain situation. 
We are actively working to develop and procure lower Rare Earth content phosphor. 
We are working to qualify an expanded base of suppliers. 
We continue to work to secure the ample supply of materials.
We will do our best to manage these costs where we can, but rises on a similar scale to those seen in recent months will mean further significant price adjustments may be unavoidable.

Why would you upgrade your lighting?

  • Outdated lighting in a large commercial or industrial building can be responsible for up to 60-80% of the onsite electricity usage

  • The savings made by new energy efficient lighting is typically the single biggest cut in electricity consumption (and carbon footprint) in one single step - up to 60-80% is possible, with every penny saved contributing directly to net profit and your cost of delay.

  • Purely as a financial investment, energy saving lighting provides a quick, guaranteed return 24 months is typical, with less than 12 months being possible in some cases.
  • There are many indirect financial benefits including reduced lighting maintenance costs, better productivity in improved working conditions, avoiding financial penalties of new stringent environmental regulations, CCL.
  • The cost and disruption of maintaining an existing lighting system can be reduced dramatically. Replacing lamps at high mounting heights may involve hiring expensive lifting equipment.  New lights can provide 5-10 operational years between lamp changes.
  • Improved staff productivity and a more comfortable working environment can be achieved when areas are lit brightly enough and/or given a more suitable "quality" of light for the work being undertaken (white, daylight quality for visual inspection etc.). Other benefist include the ability to get full light brightness instantly.
  • New lighting can address existing health and safety issues such as: ensuring that CIBSE lighting levels guidelines are met, eliminating dimness in dangerous working areas, lowering exisitng glare, replacing the risks associated with older, unsafe electrical equipment etc. This can protect a business against liability.
  • A business will be able to demonstrate Corporate Social Responsibility (CSR) initiatives and a carbon reduction strategy to supply chains and customers. New lighting also has the advantage of being a very "visual" demonstation of an onsite energy reduction project.
  • The quick return on investment ensures that new lighting is a convincing first step to take as part of a wider sustainability initiative or environmental strategy for a business.
  • In some cases - New energy saving lighting systems may qualify for Carbon Trust financial assistance. Here, a business can avoid making any capital outlay, only paying as savings are made. This allows budgets to be protected for other areas in the business, eliminating what is usually the biggest barrier for capital investment projects.

ARE YOU FIT FOR WINTER??





So we had a fairly good summer for the UK and a lovely mini heat wave at the beginning of this month!

But reality kicks in, the nights draw cold and its dark when you get up....yes Winter is coming.

If that’s not depressing enough you realise that there are less than 11 weeks till Christmas and the shoppers will be out in force.

If you’re a facilities or estate manager you are responsible for customer & colleague welfare ensuring their safety. There are some simple questions you need to ask yourself about your building or carpark lighting:

Do you have comprehensive lighting maintenance in place?

Yes or No

Are you sure that your contractor has ensured you are ready for winter?

Yes or No

Can you be sure your all lights will function when usage doubles?

Yes or No

Can you answer YES to all the following questions?

Have you had a re-lamp in the last 4 years?

Has your maintenance been completed regularly?

If you have PIR sensors, have they been checked and maintained?

Are the LUX levels in line with the British Standards?

Have you considered the potential costs of not being ready?

Do you have a reliable company you can trust to help you?






If you are unable to answer yes to any of the above then it may be time to seriously look at the potential issues you could face if your lighting is not what it should be. Poor or improperly maintained lighting can cause serious injury which in turn can lead to a serious insurance claim against your company.

Prevention is the best cure!

Reduce your energy and maintenance costs by switching


T12 Conversions

T12 8 foot tubes often represent a significant percentage of lamps installed across an estate, however with energy prices rising and an array of environmental legislation, the push is towards more energy efficient products. Weblight has undertaken nationwide T12 replacement works for a number of key clients including Midland Co-operative Group, ASDA and Sainsburys.
 
Major manufacturers have now ceased production of the 8 foot lamp – the only product now available is the basic white tube from a ‘B’ grade manufacturer, who will only supply lamps in quantities upward of 4000. In addition, the Federation of National Manufacturers Associations for Luminaires and Electrotechnical Components for Luminaires in the European Union have disqualified the production of this inefficient control gear and all stocks are now exhausted, meaning that lamps can be sourced but gear cannot be repaired to operate it. Of course, this means that simply relamping is no longer a viable option.
 
Disadvantages of T12 Lamps
  • Contain a high mercury content and are therefore environmentally unfriendly
  • They have a short lamp life of only 9,000 hours thus increases maintenance costs
  • Only 75% lumen maintenance causes loss of lamp lumen output at end of life Lamp flicker and stroboscopic effects can create discomfort and should be avoided The lamps are now only available as halophosphate hence poor colour rendering.
There is a potential risk to the site as insurance companies have recognised that the control gear in these fixtures is old and inefficient. The starterless circuits that operate these lamps can also be the cause of overheating and a potential fire risk.
Benefits of Converting to High Frequency Luminaires
  • Automatic shutdown of failed lamps
  • Silent in operation
  • Significant energy savings available from HF gear

The T5 lamp has significant benefits over the T12
  • A superior service life of 25,000 hours
  • 95% lumen maintenance
  • Excellent colour rendering presenting the colours of the products accurately. To do this, lamps require a colour rendering of 80+ (CRI)
  • Cost savings due to reduced WEEE fee impact
  • Environmentally-friendly product, RoHS compliant and contains recyclable components Substantial energy savings, as example shown below

The above is an example only based on one of our Clients estates –figures shown are not representative of all sites.
What is the Cost of delay?


The cost of delay quite simply is the revenue a company would need to generate to compensate for the high energy bills they currently pay. As a rule for every £1 spent on wasted energy a further £3 of revenue/sales is needed to pay for this. In terms of GP this significantly impacts the overall bottom line figure on your P&L.
