Dedicated Lighting: LEDs and Fluorescents

| No Comments | No TrackBacks
In new building and environmental regulations, lighting plays a key role. Even though the Wattages used in lighting seem fairly insignificant in comparison to televisions and microwaves, it is something which is easily changed for the better since the introduction of compact fluorescent bulbs.

Just to flag a couple of LED lighting blog posts - bicycle lights, to be specific.

'Alice' has posted a couple of blogs, on Electro-ramblings, on the ongoing Bike Light Project. See:



Lumen output - the key to cutting energy

| No Comments | No TrackBacks
The basic thought behind the brightness of LEDs is the Wattage. For example 8W is brighter than 3W. The more power used, the brighter the bulb. The amount of light output a bulb gives is measured in lumens.

LED Life Expectancy

| 1 Comment | No TrackBacks
LEDs have a general life expectancy of 50 000 hrs. If you use your lights for 10 hours a day, this should be 13.7 yrs. If this is correct, then LED's are definitely an investment, even the top of the range bulb would work out to cost 2.55GBP per year. Add that to the saving you would make on energy and you've got a very cost effective bulb!
