Since I'm up on jack stands cause of a car accident, I figured now was a great time to redo my tank lighting. I have power supply and drivers from Steve's LED and heat sink and more led's on the way from LEDgroupbuy.com. I plan to reuse some of the LED's I already have. I'm going from 7 blue and 7 neutral white to 14 royal blue and 7 neutal white mounted on a 4.23"x12" heat sink. tank is a standard 20g. Does anyone have any ideas on arranging the led's with the 2-1 ratio?
