    Hi,
    I want to upgrade my algae scrubber fro CFO lights to LEDs,
    The screen size will be 10"x18",  I am planning on getting 3w LEDs, 750ma, 2.2-2.6v forward. Each side will have 32 leds, 27 red (660nm) and 5 royal blue (455-460nm). I am thinking of having them 8 parallel raws with 4 leds each, similar to the design below. Do i need a resistor at the end of each series (R1,R2,R3 in the drawing below)? I am planning on getting a power driver as follows, 60w, 12v and 6A. Is it enough and am i missing anything.
    Thanks in advance
    Issa
