Madpaddy, of course you wouldn't light a gym with LEDs. The point of LEDs is that they can be used in applications where either a) not much light is needed in a room altogether or b) the light source can be close to the thing that needs to be lighted, for example a keyboard or other work area.

Sorry to burst your bubble Captain, but LEDs are not particularly efficient. In the worst case, LEDs are about equivalent with incandescents. In the best case they may be competetive with a compact fluorescent. Purpose made fluorescent fixtures blow LEDs out of the water.

In fact, LED traffic lights are far more expensive than incandescent, but have been measured to be 80-90% more efficient and they are brighter and last about 5-7 times longer to boot. Los Angeles saved upwards of 75 million dollars the first year after swapping out all their traffic lights with LED units.
I must pay more attention to what SPG says....I must pay more attention to what SPG says....[snip, because I am sure the monitors would not want me taking up the space repeating this the standard 100 times as a punishment for not listening it the first place]
