Energy Efficient Lighting

 The potential decision to sell of the firm’s prestige lighting business will come as a surprise to some, especially as lighting, in the early days of the company, defined GE.

 

GE is thought to be considering selling its lighting buisness so it can concentrate on producing large complex equipment such as aircraft engines.

GE, the company credited with inventing and mass marketing the lightbulb, is reportedly plotting to sell of its lighting division.

The Wall Street Journal reports that the firm has been talking to a number of investment banks about a potential deal.

GE was co-founded by Thomas Edison, the inventor of the first viable incandescent lamp, over a century ago and the jettisoning of the firm’s lighting business a century later could net the company up to $500 million.

The Boston based company has been gradually selling off businesses since 2004, including its insurance, credit card, plastics and security divisions.

It is thought that GE is taking these actions so it can concentrate on producing large complex equipment such as power turbines, aircraft engines, health-care equipment and trains, while gaining a considerable income stream from the very lucrative service contracts that go alongside developing these machines.

Nevertheless, the potential decision to sell of the firm’s prestige lighting business will come as a surprise to some, especially as lighting, in the early days of the company, defined GE.

GE has so far refused to comment on the rumours.

The industry is recycling more lamps and luminaires than ever, according to data from the Environment Agency.

In 2015 the number of lamps being recycled leapt by 44 per cent while luminaires were up 4.4 per cent. Commenting on the news, Nigel Harvey, CEO of specialist lighting WEEE compliance scheme Recolight, said: ‘It is particularly pleasing to see that the 2015 recycling rate bounced back up from 2014.  This is probably due, in part, to the recycling of fluorescent waste resulting from major LED integrated luminaire roll outs in business premises across the UK. The lamp recycling rate from 2013 to 2014 saw a drop when, for the first time, the data included LED lamps as well as Gas Discharge Lamps.  With very large quantities of LEDs being sold – but very few being returned as WEEE, the inclusion of LEDs inevitably reduced the rate.’

Turning to the luminaire recycling rate, he added ‘The luminaire recycling rate has increased from 2014 to 2015.  However, the tonnage of luminaires collected in 2015 is only 5 per cent higher than in 2014.  The rate increase is therefore primarily due to the 12.7 per cent reduction in the tonnage of luminaires reported as put on the market.  This reduction is likely to be a result of dual use classification, which means that any luminaires that could be used by consumers are now out of scope of the WEEE Regulations.’

  • The Environment Agency data also reveals that membership of Recolight has increased more than any other UK scheme. The number of members increased by 23 producers between the end of 2014, and the beginning of 2016.  That is also Recolight’s biggest annual increase recorded since the scheme was established in 2007.

LED lights dont attract insects. True or false?

 LED lights don’t attract insects. True or false?

Gordon Routledge, lighting expert and publisher of Lux, investigates a widely held belief about insects’ lighting preferences.

 

Ultraviolet light has been exploited for years to lure ­flies to an early death by electrocution – as can be seen in the bug traps at any supermarket’s fresh meat counter. Over the years I have heard from numerous sources that, because LEDs don’t emit ultraviolet light, they don’t attract insects.

“Given a choice between no light and a white light, do insects give up and go home, or do they ­fly merrily around your head, laughing at your feeble LED fittings and making the occasional landing on your neck to suck your blood?”

At first glance the statement seems to pass the common sense test. I didn’t start to really question it until I left a retrofit LED bulb switched on to test in the garage for six months, during which time the diffuser accumulated a significant number of corn flies. If there’s no UV, what is it about LEDs that’s so irresistible to insects?

 

The search for truth

Spend a little time trawling the internet and you will quickly unearth a wealth of articles, reports and anecdotes on UV light, insects and LEDs, frequently contradicting each other and sometimes with a strong smell of snake oil about them.

A few calls to the Royal Entomological Society put me on a clearer track, and I was directed to some useful papers on insects and light. Perhaps the most pertinent was undertaken in 2005 at the University of Agriculture in Faisalabad, Pakistan, titled ‘Insect orientation to various colour lights in the agricultural biomes of Faisalabad’.

The research was carried out by erecting a number of illuminated one metre-square screens in two separate locations, each six metres apart, and collecting the insects that became trapped on each panel at half-hourly intervals.

The study found that 60-70 per cent of insects preferred light at the blue end of the spectrum. But that doesn’t mean the others stayed at home – insects, as it turns out, have a wide variety of preferences. Eighteen per cent headed for a white light, another eight to 10 per cent went for yellow and two per cent headed straight for the red light district.

This is all very interesting, but what if you’re the only light in town? Little research has been carried out in the area of general lighting, and more specifically LED. Given a choice between no light and a white light, do insects give up and go home, or do they ­fly merrily around your head, laughing at your feeble LED fittings and making the occasional landing on your neck to suck your blood?

 

Bugged out

After the success of the North Yorkshire garage LED trial, I took the opportunity to extend the study to my brand new LED-lit kitchen. Leaving the doors open last week, I can report that the local midges are more than happy to hang around on a wall under an LED downlight, where they are soon joined by a selection of moths and ­flies.

“It appears that insects, like humans, have quite complex and diverse tastes in lighting, and may well spend hours debating the colour rendering of a dung heap under different sources”

And with lower levels of radiated heat than traditional light sources, they are far less likely to get burned in the process. It’s only a matter of time before word gets around in the insect community about this cool new hangout.

It appears that insects, like humans, have quite complex and diverse tastes in lighting, and may well spend hours debating the colour rendering of a dung heap under different sources.

But, also like humans, they’ll make do with what light there is. I’m sure the option of hanging around in a dimly-lit Starbucks and divebombing freshly-made cappuccinos is preferable to the risk of being spattered across a truck windscreen on the M25 while trying to find a nice, white HID lamp.

So next time Snake Oil Bob drops in to hawk his wares on the basis of their anti-bug properties, send him packing with an LED torch to Faisalabad, and he can explain to the local insects himself that it doesn’t emit any UV – if they’ll stop biting him for long enough to listen.

Here comes the graphene LED bulb

Here comes the graphene LED bulb

Getting that graphene glow: Graphene Nobel Laureate Sir Kostya Novoselov (l) and UK Chancellor of the Exchequer George Osborne light up with one of the graphene LED lamps at The University of Manchester’s National Graphene Institute.

LUX Reports: For LED bulbs, not only are prices coming down, but also the bulbs themselves keep getting better. The latest example: in a few months you’ll be able to purchase a light bulb made with everybody’s favourite miracle material, graphene.

The bulb, from a UK startup called Graphene Lighting, ‘Is expected to perform significantly better and last longer than traditional LED bulbs,’ a press release from the UK’s The University of Manchester states (it must be a sign of progress if we can now refer to ‘traditional’ LED bulbs!). ‘It is expected that the graphene lightbulbs will be on the shelves in a matter of months, at a competitive cost.’

That’s a lot of great expectations from the university, which is excited because, for among other reasons, it has a financial stake in Graphene Lighting. The company is a spin-out from the National Graphene Institute, founded at the university with British and European government funding to advance commercial applications of graphene.

Graphene Lighting will coat a bulb’s LED chips with graphene, improving the bulb’s heat removal process, a university spokesperson told Lux. (For those who need reminding: LED bulbs give off light from semiconductors known as light-emitting diodes. And while LEDs are far more efficient than conventional bulbs, they’re still inefficient enough to yield heat that must dissipate).

According to the press release, the graphene leads to ‘lower energy emissions, longer lifetime and lower manufacturing costs.’ The university would not quantify those improvements.

A BBC story  suggested that the bulb will cut energy consumption by 10 per cent over other LED bulbs because it enhances electrical conductivity. The Financial Times (registration may be required), which appears to have broken the story about the bulb, also suggested a 10 per cent improvement.

The university spokesperson told Lux that ‘it’s too early to say,’ whether the 10 per cent figure is accurate.

The BBC story said the bulb uses a filament-shaped LED. The FT said it will be priced lower than the ‘£15 and more’ that it said is typical for comparable dimmable LED bulbs.

Lux has requested an interview with Prof Colin Bailey, a director of Graphene Lighting and deputy president of The University of Manchester, to find out more about the lamp’s workings.

The University of Manchester is the birthplace of graphene. Scientists Sir Andre Geim and Sir Kostya Novoselov first isolated the wonder material there in 2004, an achievement that earned them the 2010 Nobel Prize in Physics.

‘This lightbulb shows that graphene products are becoming a reality, just a little more than a decade after it was first isolated – a very short time in scientific terms,’ Prof Bailey said in the press release.

Graphene is a one-atom thin sheet of carbon heralded for having the strength of Superman and conductivity that’s 100 times better than today’s silicon-based semiconductors.

While graphene orginated in the UK, at one point China had shot ahead in the graphene intelllectual property race .

Potential uses span from building materials through energy and electronics, including semiconductors, solar cells and of course, light bulbs. The BBC noted that it is already used in tennis rackets and skis.

Two years ago, researchers in South Korea and Vietnam said that graphene would help dissipate heat from LED bulbs, and which would help make bulbs brighter.

Graphene Lighting appears close to delivering a graphene lamp. They’ll be under pressure to come through, lest they deflate expectations.

The Down Hall Hotel, one of the UK’s most established country house hotels, has achieved considerable energy savings on lighting thanks to a simple retrofit to Megaman LED lamps. With Phase 1 of the project concentrating on the main function rooms, lounge and anti-lounge areas, the current estimated figures are 7736kw of energy saved per annum which equates to an annual CO2 saving of 4.21 tons.

Located in Hatfield Heath on the Hertfordshire/Essex borders, Down Hall was built in the Italianate style of architecture, which was a distinct 19th century phase in the history of Classical architecture and the hotel dates back to 1322 with luxurious interior and ornate ceilings, all set in 110 acres of parkland.    The hotel has many high ceiling function rooms including the Prior Suite, and this was the first room to be considered for the new LED lamps.

With chandeliers and wall lights in constant use, the old Halogen 28W lamps were constantly failing which meant a scaffolding tower had to be erected each time to replace the lamps, taking up valuable maintenance time and causing serious potential health and safety issues.  On review of the lighting it was agreed to switch the existing lighting to Megaman’s 5w candle lamps in warm white, which also offer dimming capabilities for changing the ambience of the room at different times of the day and evening. On completion of the Prior Suite, the staff at Down Hall were so delighted with the result that the other function rooms, namely

Rookwood, Lyndhurst, Harley and the lounge and anti-lounge, were also changed to the new LED lamps. Bob Parker at Down Hall commented “We are extremely happy with the new LED lamps which, apart from the energy savings achieved, actually look better and complement the existing fittings, plus they offer 50,000 hours life.   The light output is excellent and staff are commenting that the new lighting has improved the whole ambience of the building.  We are now in the process of putting Phase 2 into action which will include the Bridgeman Selwin Suites which is our main ballroom for wedding receptions”.

Novel Energy Lighting supplies LED lighting to the hospitality sector and can provide many references of hotels which have been retrofitted. We sell LED lamps and fittings, and can provide services such as surveys, lighting designs, and installation to help you start saving energy as quickly as possible.

LUX Reports: Hadrien Bera leads a team of 20 engineers responsible for the overall asset management of London’s grand hotel Claridge’s in Mayfair. It’s a challenging role; requirements to save energy aren’t easy to balance with the need to maintain the look and feel of a lavish Grade II listed building with art deco interiors, frequented by the royals and sometimes referred to as the ‘annexe to Buckingham Palace’.

 Lux spoke to Bera to find out how he plans to make the lighting in the prestigious, 200-year-old building more efficient.
1423146895_hadrien_bera_001_edited_LR
Lux: What are the biggest lighting challenges you face at Claridges?
Bera: We’ve got a lot of different systems and it is difficult to keep enough stock because a lot is custom-made. That forces me to plan ahead and to create stocks of critical spares so any issues would have as little disruption to the hotel’s operations as possible.
We’ve got chandeliers in the main reception that use incandescent candles, which also comes with challenges: I am looking at replacing these bulbs which are energy hungry and more and more difficult to source but I cannot just replace them with anything. This is one of the first features our many guests will see so it has to look in tone with the rest of the art deco style of our lobby. It’s easier to be creative and to focus on energy efficiency in the back of house areas.
Have you had much experience using LED technology?
We’re replacing all the filament lighting in our suites with LEDs. The project is still in the early stages and I’m experimenting with different LED manufacturers. With this kind of major refurbishment project, we use lighting designers who will specify the best fittings to meet the operational requirements and also the best lighting outputs.
We’ve got 197 guest bedrooms and the amount of lighting will vary from 10 to 50 light fittings per room. In all our latest rooms, the lighting is 100 per cent LED, from the strips in the pelmets and the wardrobes, to the candles in the bedside tables, the GLS in the standing lamps and the spot lights. At this stage, about 50 bedrooms are fully lit with LEDs, so we still have a long way to go.
Do you have energy reduction targets?
There is not a set target in regards to energy saving. The aim is to ensure that we do not compromise on quality and that we do this in the most sustainable way possible. Then, it is up to me to propose projects to accomplish that. I obviously ensure that the energy is not wasted by having a strict maintenance program but this is not enough, we need to be as proactive as possible to ensure we remain at the top of the game.
Is it difficult to justify investments in energy-efficient lighting?
It’s relatively easy if payback is short. Any investment that would take longer than three years to pay for itself would be difficult to justify and anything that would take less than two years would always be preferential. A business case needs to be submitted to show and justify the return on investment. This requires a lot of research and months of trials. That also gives us the time to negotiate with our lighting provider to make sure that we get the best products at the best price.
In my opinion, many people had a bad first impression of LEDs when they were at their developing stages. This is slowly changing but it is up to us, facility managers, to change this by shortlisting the best possible applications, showing the difference in regards to the ‘feel’ LED can provide, the energy consumption and the associated CO2 emission reduction. This is important and this is why this process is so lengthy.
How do you go about installing new lights without disturbing guests?
When we’re satisfied with the lighting products, we have to do a whole bedroom in one go. We’ll do a survey first to ensure we know exactly what is required, place the order, block the room off and then go in one day and replace all the lighting. Once the room has been converted, we would leave it for a couple of months to gain additional feedback from the rest of the team, from the guests and from the hotel management team before we move on to the other rooms.
For the corridors, the same process applies but the work would be carried out at night when we would convert the corridor into sections, which can take up to two or three nights. This is to ensure that the task doesn’t affect the operations of the hotel or disturb our guests.
What other lighting plans do you have for Claridges?
Façade lighting is another project that I am working on. The hotel is a listed building and its architecture is spectacular. It deserves the best façade lighting we can obtain. There are, of course, different ways to achieve this and everything we do has to be submitted to the authorities to gain the mandatory planning permissions.
At the moment I am at the design stage where I am reviewing with a lighting consultant how we can achieve the best results. In previous Lux editions, there have been a lot of interesting case studies, especially the feature on the Science Museum façade lighting replacement. The result was amazing and it was interesting to see their process.

Sunny Boy: She’s already up, and he’s about to get there himself, thanks to the sun-like lamp above the bed, programmed alarm-like to ‘rise’ and slowly brighten. Binoculars cost extra.

Lux reports: Move over wonder drugs. Make way for wonder lights.

That could be the tag line for start-up lighting company Sunn, which is launching an app that commands its and others’ LED smart lamps to mimic the 24-hour light cycle from the sun and moon – an act that delivers invaluable holistic health benefits judging by the fresh-faced users in a video on the Sunn website.

‘Imagine if your lights told time through subtle changes in color and brightness,’ note the subtitles in the video from the Los Angeles-based company. ‘Imagine if your lights put you in touch with the rhythm of the sun to help ease your transition into the day to promote alertness while you work and help you shine through the winter blues. Imagine if your lights brought the sunset into your space glowing warm at night to help you relax. Imagine if your lights helped you wind down for bed. Imagine if the moon was there to guide your way late at night.’

Well, you are going to have to imagine, because while the app works with wall- or ceiling-mounted plate-shaped lamps from Sunn, those products are not yet available. (The app also works with Philips’ Hue LED bulb and with the smart LIFX LED lamp).

Sunn’s website gives consumers a chance to ‘pre-order’, which fits with the company’s grassroots spirit. Sunn on December 20th closed a successful 29-day ‘crowdfunding’ campaign on the website Kickstarter, easily exceeding its $50,000 goal by landing $117,106. (For any of you who might have just arrived from Cro-Magnon days, crowdfunding is an internet process in which funders donate money to a company).

‘We’ve completed production-quality versions of both Sunn lights,’ Sunn says on Kickstarter. ‘This means we’ve sourced and completed tooling for many of the large components which is typically the largest hurdle in bringing a product to market. We’ve also completed the first version of the iOS app as well as the cloud-based backend that will support the Sunn app on iOS, Android and web platforms.’
Sunn, which also has offices in Chicago, New York, Poland and Denmark, says it has lined up a manufacturer with operations in Europe, Southeast Asia and North America.

So, what exactly does this sun and moon show do for us?
‘Sunn lights provide dynamic, healthy lighting experiences,’ its Kickstarter site notes.
As Wired magazine reported, Sunn can help combat depression that afflicts people in northern climes in the dark of winter, a condition otherwise known as seasonal affective disorder (SAD).

While white light lamps already exist to target SAD sufferers, Wired noted that Sunn’s lamp marks a kindler and gentler approach that subtly copies the sun’s ebb and flow rather than blasting a person for half an hour with intense light. Users in, say, Iceland can adjust the Sunn lamp to cast shifting ‘sunlight’ indoors all day in a manner akin to, say, Bali, the article said.

Sunn’s app can: brighten a light gradually in the morning as an alarm; sync the light to match the outdoor sun; match the sun at a desired time or location; wind down the lighting at bedtime; provide moon glow.

We’re all still in the dawn of understanding the myths and realities of modern lighting’s potential health benefits. It’s good to know that companies like Sunn are rising to help figure it out.

Optics in the new OSRAM classic bulb-shaped LED lamps ensure uniform light with beam angles of up to 300°

The unique optic by OSRAM

Whether the light of a lamp is perceived as being pleasant by customers depends on many different factors, for example color temperature and luminous intensity.

The distribution of luminous intensity in the so-called far field is also important, meaning where light hits walls, floors or table surfaces, and of special importance in this respect is that light is distributed homogeneously and that no shadowing or linear structures are seen.

These tasks are achieved by optics assembled within the LED lamps with classic forms, i.e. pear, candle or drop shapes. In the past this often presented a problem particularly with clear lamps, because with these lamps such optics can be seen from the outside, meaning that these are not only a functional element but must also be visually attractive. In this respect the optic also ensures that the “technology” of the lamp, meaning its LEDs and electronics, cannot be seen from the outside, making it more attractive for consumers.

Optics in the classic bulb-shaped lamps in the new OSRAM LED portfolio have been designed to largely exclude irregularities such as dark shadow lines in the far field light and to achieve homogeneous light distribution, achieved by the particular form of the plastic optic, developed specifically for the new lamp generation.

The optic design was challenging due to the high technical and aesthetic demands, and was developed with the aid of in-house programmed software. Optics in the new OSRAM LED classic portfolio radiate at angles of up to 300° and are based on a uniform optical concept across all lamp types.

This achieves a uniform design appearance, and also shorter development periods and lower costs because the optics of various lamp types are compatible with identical mechanical components. This modular construction principle has been consistently applied by OSRAM to all components in its new LED lamp portfolio.

Philips LED Lights give Smart and Durable Lighting

Are you conscious of your increasing electricity bills ? At least 25% of that bill will be due to lighting, from using traditional bulbs and tube lights. Traditional lights like incandescent bulbs emit a lot of heat, as they use chemicals like mercury and phosphor to glow. What’s more, these lights are known to consume a lot of electricity to produce light, which is why your energy bills are so high every month.

Philips-LED

LED lighting technology, uses electricity in a smarter way.Unlike traditional incandescent bulbs, LED’s do not require any warm up time to emit light. Therefore you get instant illumination when switched on. And since they consume less energy they don’t heat up excessively, thus reducing fire risks.

For top quality LED lights, consider the leading lighting manufacturer, Philips. They produce LED  lights come different product ranges like LED GLS bulbs, spots, tubes, candles, lamps, etc. What’s more, each of these lights come of different wattages to suit your lighting needs. For example, the Philips LED MR16 lamps come in wattages ranging from 4W=20W equivalent, 5.5W=35W equivalent, 7W=35W equivalent and 10W=50W equivalent to a standard halogen lamp. Thus, these lamps will be the right lighting choice for areas which need a substantial amount of constant light like retail outlets, restaurants, hotels, etc.

Novel Energy Lighting supplies all these fabulous LED lights at very competitive rates, including the entire range of Philips LED lights. These lights are known to deliver an excellent quality of light, which exceeds that of the brightest incandescent bulbs. They even have a long lifespan of around 40,000 hours, which is far more than traditional bulbs which last only for 1000-2000 hours. Since they last for such a long time, they reduce the need for you to keep replacing them at frequent intervals.

The best part of Philip LED bulbs is that they are designed as a retrofit replacement to your standard incandescent bulbs. Once you install and start using LED lights, you will notice that your lighting costs will get cut down by up to 90%. Their amazing lifespan will also give you a further savings on your maintenance costs. When you come to Novel Energy Lighting, you will get a diverse product range of LED lights along with other accessories like dimmers, sensors and transformers. We also stock other major brands like Megaman, Heathfield, Osram, Verbatim, etc. which you can choose from.

LED’s Reduce Carbon Emissions and Save Electricity

Luxmagazine.co.uk recently reported that, a leading provider of student housing, plans to upgrade all of its 120 residences with LED lighting in a £21 million, 2-year retrofit across 23 towns and cities.

led

The company, Unite Students, says that the more efficient LEDs will cut energy consumption by 10-to-15 percent per year, while also sparing the annual CO2 emissions equivalent of about 400 typical British households, or 2,000 tonnes per year.

Unite is working with lighting giant Philips to install about 300,000 fixtures plus 85,000 sensors and dimmers that will, among other things, adjust lighting levels accordingly when they detect that students have left or entered a room or common area.

It is placing the lights in corridors, kitchens, lounges, reception areas and outdoors. New bedroom lighting will include dimmers as well as lamps that can change colours at the push of a control (Philips ‘LivingColors’ brand), which will ‘allow students to personalize their lighting to suit study, relaxation or socialsing,’ Unite says in a press release. Something for everyone among the 41,000 students, from budding Einsteins to Casanovas (those without lava lamps, anyway).

Unite says the project should also help it save maintenance costs because LED bulbs last longer than the lighting it is supplanting.

Unite is contributing £9.6 million of the funds. The remainder comes from Unite’s “co-investment partners,” the release states. The scheme is the second in recent weeks that should help upgrade lighting at UK universities.

The 10-to-15 percent energy saving is modest next to typical vendor claims that LED bulbs reduce energy needs by around 80 percent. Unite did not say what type of lighting it would typically replace, or whether it would offset some of the energy reduction by installing more lighting than what currently exists.

Novel Energy Lighting understands all your energy and lighting requirements, and provides you with quality LED products like bulbs, tubes, lamps, sensors, etc. from some of the most reputed brands in the lighting industry such as Megaman, Heathfield, Osram, Toshiba, and of course, Philips. One of our LED lamps, the Megaman LED GU10, stands out from the rest as it uses energy efficiently and has a long lifetime. It delivers 500lm from just 7W, enabling it to produce light for a staggering 50,000 hours.
