I want to experiment with different colored LEDs (Red/Purple) in my current cree RB/CW setup and want to control them independently from my whites and blues Link to comment
lynxer Posted January 11, 2012 Share Posted January 11, 2012 http://www.dealextreme.com/p/700ma-3w-led-...r-90-265v-81780 Would let you wire to a plug and put on a timer. OR Consider this 9w version (3 x 3w) and you could wire 3, and have less cords/timers? http://www.dealextreme.com/p/650ma-9w-led-...r-90-265v-81777 Good prices too IMO, however they do ship from overseas obviously.
