First on-site test for LED lights in the kitchen
Top: 4 CFL tubes, one not visible on the left side. The long ones consume 14W, the short ones 8W.
The single LED bar in the bottom half takes 3W. Judging from the brightness of the thing and the brightness of the rear wall, I think I could get the same overall illumination with about 6 LED modules, equaling in 18W + power supply losses. But good switchers are quite efficient. This would be a 15V system.
I'm still waiting for a batch of individual 0.5W LEDs in warm/cold white. They'll get a chance to show off as well. If they win the race, I'll be able to use a spare 5V, 2.6A switching power supply for these for the beginning. I've checked it for its stand by power requirements and they were a bit high. 1W standby losses would cost me about 6€ per year. Efficient switchers with low standby losses can be had for 12 to 20€. I've already got one (5-12V, 2.25A) and my power monitor couldn't detect any difference whether it was plugged in or not.
