[ame=http://www.youtube.com/watch?v=TbU_NTxorFk][:] Advanced LED-technology [:] - YouTube[/ame] I came up with this invention by accident when I inserted RC-helicopter controller into TV video input. I then noticed, that it has a very "saw waveform". Then I realized, that these controlles can be used to control LED-lights so that they blink all the time. It should save some energy and it cools down the LEDs so much, that I think you can give them about 10 times more voltages as usual. Now I am running about 4 times more as usual power. The LEDs are very cool to touch, not even warm. Now I am experimenting how the plants react to the blinking light. They should sprout in few days.
