The heatsinks came as is. All I did was cut 2" off the length to make it work better for what I'm going to use these lights for and then drilled and tapped them for machined screws. These are being built to light my algae scrubber. Or they can double as a fuge light.
18 leds per sink. 12 osram red, 6 xpg 4500k neutral white. They only need to light a 10"x10" area. But I'll probably get a little more out of it then that. I chose the layout of the wiring for a particular reason but it's not entirely finished in those photos, no. I do plan to drill a couple more holes in the heatsink to pass my + and - wires to the driver/drivers. There's more to come, I pretty much just got started today. My LPF drivers will be here on monday. Then I just need to decide on some fans and how I want to enclose everything since they're going to be sitting darn near in my sump.
