Labour urges incentives for LED bulbs

LED's are in fact some of the best light souce to replicate natural daylight (the best lighting) as their CRI ( colour rendering index ) in most cases is between 80 and 98 ( 100 being daylight ) and their colour temperature for neutral white colour is between 5000K and 5500K (daylight being 5000K)

On the other hand most fluorescent tubes and energy savers have a CRI of 65 - 80 in the neutral white colour also between 5000K and 5500K. Normal halogen and tungsten bulbs have colour temperatures of 2,500K to 3,500K which is too warm and does not render blues well enough whilst metal halide bulbs are too cool (6,700K to 9,000K) and do not render red properly.

We manufacture our products specifically for offices, hotels, and business establishments with size, weight, and aesthetics in mind.

Michael Falzon - actually our lighting gives off the same light as a 20W halogen lamp but just consumes 1W.

Edward Bartolo - The cost of these LED lights are very competitive when compared to what is on the market, surprisingly even some lower standard LED alternatives in our local market are more expensive then what we provide.

The light intensity used to be limited, however with our new technology we have opened new bounderies and have created said products which can replace other spot lights and compete on light, heat generation and lighting output.

Check out our website www.smartlightsystems.com for an idea of what products we are manufacturing in Malta, and feel free to contact me shouldyou require to see them in "action".

I refer to the above report. This article says that these lamps are manufactured locally, which I seriously doubt.
Anyway even if they are just being assembled locally, whoever imports such energy saving lamps, should be financially encouraged, to do so by the government.
Admittedly LEDs are still being developed and consequently expensive, but it seems that they could be a solution towards reducing our energy consumption.

Although I appreciate your explanation regarding the physics of the LED`s , I can tell you that after the Government raised the W/E bills I changed all my bulbs and got them all LED`s from Hong Kong through ebay. I can easily say that they work great and as regards to the light they emmit they compare very well to the traditional energy savers.

I have recently purchased a similar product from abroad and I am quite satisfied with their performance. These bulbs produce comfortable lighting and the ones I have 60 LED's of which I used 4 to light a medium sized room. However the manufacturer claimed a consumption of 1 watt each but when bench tested these consumed an average of 5 watts each which I still consider quite reasonable.

These lighting devices, are prohibitively expensive. Besides that, the light they produce, is irritating and totally unnatural. As far as I know, LEDs can only produce a very limited range of light wavelengths. This is in great contrast to the spectra emitted by incandescent lamps. Natural light is produced by thermal agitation and not by electron-hole recombination in a semiconductor. This means, that more research is necessary and that, the output light spectrum must be made to mimic natural light to minimise eye fatigue.

Saying that currently available LED's at 1W are comparable to 70-80W is not quite true.
Realistically priced LED's would compare to say 15W for a 1W LED at best.
