LED tube lights use approximately half the electricity used by a fluorescent tube – and that should be very appealing to anyone paying the bills! BUT… the problem is that until recently, the cost of the tube has been so high that the savings do not cover the purchase price within the life of the tube.

All that has changed as the cost of the tubes has halved in less than six months due to increased volumes and new technology that sees more than 100 lumens per watt being emitted.

These supplier price decreases mean that our tubes are now well priced and can fully return their purchase price within three years of purchase and this leaves a full additional three years of savings.

It is time now for office managers to start thinking about the change to LED tube lights. Not only will you save money, but you will reduce maintenance costs because unlike fluorescent lights that last 4000 hours, LED tubes go for 30-50000 hours. Oh, let’s not forget you’ll be halving your lighting carbon footprint! Take a look at our LED tube light offering here.

The good news for consumers is that the price of LED lights is headed in the right direction – downwards. The one type of LED lighting that we have been waiting to see come down in price is the LED tube. These fluorescent tube replacements are only 50% as energy efficient as the fluorescent tubes they replace so the cost dynamics are really less in their favour than downlights where a 3W LED can replace a 35W halogen light.

So, to see prices on an 18W tube fall from US$27 down to US$18 is gratifying. It means that breakeven timing will fall into a more reasonable time period and make these lights an option. At the same time, the latest ESKOM electricity price hike is also helping to make even a 50% energy saving more attractive to the relatively high cost of the LED tube light.

To make matters even better, consider the newer high power LEDs which are putting out more lumens and that means we can go down to 16W and still get the same light output as a 36W fluorescent tube.

It’s time to think about LED tube lights for home and office applications. Remember also that you’ll be doing your bit for carbon saving as you’ll reduce CO2 emissions by half while we drop our prices to help you do this.

Who would have thought that we’d be holding a 20W LED replacement bulb in our hands in 2012? Well we are, and thanks to LED light manufacturer TESS, we have the first 2000 lumen output bulb that easily matches a 125 watt incandescent bulb. Similar in size to a normal incandescent bulb, the secret of this bulb is a 100 lumen per watt LED luminous output system and an advanced thermal dissipation technology that includes vents and a small internal fan that shunts hot air out of the casing. Pretty neat!

Longevity? Well lumen decay is good, and 70% of the original lumen output is maintained at 40000 hours. Our only concern here is the longevity of the electronics in a bulb putting out serious light. That said, the colour rendering index is as expected – around 70, and with CE, UL and FCC certifications, you are fairly certain of a well designed product.

No one is talking about cost and while that may be the least pretty part of the equation, the product is likely to gain ground quickly. Everite are expecting a 60W replacement to dip below US$10 in latter 2012, so who knows what this bulb will cost. Our guess, US$19-24.

All in, impressive and the sign of things to come in 2012

What a joy to be in the same room with the world’s foremost experts on LED technology at the LED Forum held recently in Guanzhou, China (February 2012). They were all there – CREE, Philips, OSRAM, GE…. and all were upbeat about prospects for LED lighting in the year ahead. Great technological strides have been made and product upgrades are imminent for most of these manufacturers. Current lumen output per watt (l/w) will rise to well over 100l/watt in production led lights from the current average of less than 80l/w. That is good news, but it gets better with significant reductions in the cost per lumen too. Take CREE for example – the cost of their technology is less than 10% today of what it was 6 years ago. At the same time lumens per watt have increased from less than 50 to over 100 today. Extraordinary! It’s much the same for Philips,  Osram and GE.

This all bodes well for the adoption of the technology by more and more people. In his book, Crossing the Chasm (which focuses on the understanding of new technology adoption), Geoffrey Moore notes that the key to the success of any new technology is getting across the gap between the early adopters and the mainstream users. There are now signs that this is happening given the demand statistics in the industry. This will further power the quest for more lumens at less cost and is responsible for the mega R&D budgets in play at these key manufacturers. Take CREE for example with its $100m R&D budget in 2011!

Expect some significant new LED light offerings in 2012… and to back all of this up… Philips is now estimating a 45% LED penetration rate by 2016…. very much in line with GE’s forecast of 80% by 2020.

One more time – buying an LED light based ONLY on the number of watts (W) is a BIG mistake. Why?

Well incandescent lights, like a 60 watt bulb, put out a fairly constant amount of lumens per watt of electricity used – no matter what the brand. Simply stated, look at lumens as being the measure of light output of a light source. The more lumens, the brighter the light. So buying a 60 watt bulb from brand X or Y or Z will not result in a dramatically different lumen output and you can have a high degree of confidence buying by the number of watts.

Not so for LED lighting. Different manufacturers (and there are hundreds) produce lights that have very different “lumen per watt” outputs. Using older technology, the LEDs may only reach outputs of 50 lumens per watt. So buying a 3W LED light will give you about 150 lumens of light.

More recent technology offers over 100 lumens per watt and so a good 3W light can offer 300 lumens of light output.

That is the difference between a light level that allows reading and one that will cause eye strain.

So do not buy a light that does not have the “lumenous flux” rating clearly stated. If you don’t, you’ll be playing Russian roulette when you turn it on – not knowing what you are going to get!

What you will need to know is the lumen output of each of your current lights. For example, a 60 W incandescent bulb puts out around 650-750 lumens. So you need an LED bulb that can match this.

Look for the lumen output, not the wattage!

By 2020, 8 out of 10 lights you see will be LED lights. The lighting revolution is no different to the communication and information technology revolutions that have driven our development.

So what are the 10 great reasons to make the change?

1. Low efficiency

Do you really switch on your lights to heat up the room? No! But 85% of the electricity going into your incandescent lightbulb is emitted as… heat! 60 Watts of energy ends up heating up your room… not great!

2. Longer life

Incandescent lights last for 1000 hours… LED lights last for 30000-50000 hours. A big difference…

3. No UV radiation

Yes, UV radiation is emitted by our current lighting. You are not about to get a beach tan from your lighting, but UV light is an issue, and it will impact fabrics and paintings. LED lights have no UV emissions.

4. Mercury..

Fluorescent lights contain mercury! LED lights contain none. Your choice!

5. No glass

LED lights are made of plastic and aluminum…no glass. So there is no safety issue and no glass that can shatter and cut.

6. Color rendering index

How “real” are the colors under different light sources? Is pink really pink? Under fluorescent light, you may see about 65% of the “real” color. Incandescent lights are better at around 90%, but LEDs come in across the board at around 80-90%. So similar for LED replacements of incandescent lights but if you replace fluorescent lights, you’ll have a great reason to change your lights.

7. Power efficiency

We’ve talked about lumen efficiency per watt of electricity. But what about power efficiency. LED lights use from 2-10 times less power for the same light output. Incandescents  put out less than 15 lumens per watt (consider lumens as a measure of light output). Enter the LED light – 7 Watts at 100 lumens per watt. 7 Watts of electricity will cost you a lot less than 60 Watts! That’s a great reason to replace your lights with LED lights!

8. Directional light

LED lights emit light where you point them…not behind them like an incandescent light. Direct the light where you need it…who needs the ceiling lit when you are more interested in the light on your dining table?

9. Color

You can literally make your LED lights in any color – some even change color with a remote control. So mood lighting is possible and not only can you dim them, but change color as you need to.

10. Finally, safety.

LED lights run on 12 to 24 volts. So a broken bulb will not kill you! A pretty good reason to change your lights to LED lights!

So there are 10 reasons… why not contact LED Lighting Solutions to advise on your LED light replacements.

Y.F. Yeh, Everlight ‘s Chairman, has stated that led light bulbs will drop to less than US$10 in the second half of 2012.

This will come on the back of a soft first half of 2012 and will be driven by stronger demand after June 2012.

LED lights are gaining popularity as consumers begin to understand the energy saving potential and manufacturers hit higher lumen/watt figures and quality improves. Quality improvements are the key to increasing confidence in the industry, where over promising and under delivery are common. Hopefully, softer demand in H1 2012 will drive fly by night companies out of business and will leave more genuine suppliers like LED Lighting Solutions in a better position to advise customers and provide high quality lighting.

All in, this bodes well for the LED lighting industry and more importantly, for the consumer.

LED lighting facilitates education in Africa

 

It has only been 20 years since Africa was introduced to the cellphone. In that time, millions of people have gained access to a communication tool that has changed lives and kept friends and families in touch in places that would never have been reached by land lines.

A similar kind of revolution is taking place in Africa – lighting. Light is key to the social fabric of most societies – allowing people to meet, socialise and work after dark. In so many villages across the continent, light is either provided by fires, paraffin lamps or candles. Electricity is a luxury for many – either not available or too expensive to connect and use.

If you’ve ever tried to read a book by candlelight or the flicker of a paraffin lamp, you’ll know that after a while, the low light level and the flicker will tire out your eyes. Yet millions of students study by candle light or paraffin lamps every day. Until now there just hasn’t been an alternative.

Enter a low energy consumption light source (LED lights), a mechanism to create power (solar cells) and a cheap way to store energy (rechargeable batteries).  While solar and battery technology has been around for some time, led lighting has only recently become viable with higher lumen outputs that make their performance acceptable. But that is not the only reason that change is about to accelerate. What will drive the change is the cost reductions in all three technologies.

In fact, with ever increasing oil prices trading off against technological breakthroughs and scale advantages of these new technologies, pricing is coming within range of “affordable”. A 2 watt solar cell with a battery and a series of small LED lights can light up a small house and now with improvements in quality and longevity, the upfront cost of purchase can be recovered very quickly. Thereafter, the lighting is effectively free and plentiful. All this thanks to the amazing low power consumption of led lights. With over 100 lumens per watt now becoming the standard, just 3 watts can light up a desk or a kitchen area with enough light to see and work by.

Besides the cost recovery angle, the quality of the led lights is far superior to the alternatives anyway, and so students can study with cool white light that does not stress the eyes.

As we move through 2012, and the cost of led lighting declines, and new technologies impact the solar cell and battery components, expect to see led lighting move through Africa at a rapid pace. Perhaps not as fast as the cellphone, but like the cellphone, it will bring welcome changes to the social and educational environment in Africa.

A World Bank assessment of lighting in Tanzania found that 37% of people (the largest single grouping in the study) wanted improved lighting for the impact it would make on the education of their children. They said that it would allow their children to do their homework at night.

This concept may be foreign to those in developed countries, but in Africa, candles and paraffin lamps are mostly used by children to do their homework. The flicker and poor light quality often leads to eyestrain and concentration problems with shorter study times being the result.

LED lights are low power consumers and are thus perfect for use with a small solar panel and rechargeable battery pack. Yet low quality led lights that fade very quickly (lumen depreciation) and sub-standard battery packs that do not last more than a few hundred cycles, are damaging the market. Poor people cannot afford to make mistakes on new technology and given the social dynamic of African communities, word of failure spreads fast.

We need to ensure that only good quality led lighting finds its way into the market, and we need to encourage it. Education is the key to development (and to buying good quality LED products), and until we recognise that and do everything needed to improve it, we will not see the growth in Africa that we all wish for. Promoting affordable and useful lighting technology is one way we can do this – and as LED lighting professionals we also need to educate the consumer about the technology to avoid damaging what has to be one of the most important technologies of the millenium.
