There are a few prototype white LEDs now that can match and possibly even exceed CF efficiency, but they're not available at a price that a normal mortal would want to pay.
Mmm. Back in 2000 I built a pair of 6 LED lights on a breadboard to provide low-level lighting in my shed at night. It's enough that I can see to get in the door, and get things. Not enough to work by, but that's what the halogens are for.
They have been in use for 7 years now, 24*7*365, powered by the shed's batteries. Total power used has been:
3,600 wattsOver 7 years. Not too bad.Compare that to a night-light (4w) which would have used:
24,500 watts. Chris
