Worked on a little project this weekend
. I got my LED light for this tank built. Went with 3 3watt Cree cool whites and 1 3watt Cree royal blue. All on a dimmable driver. I painted the heatsink black for a cleaner look. All I still need to do is figure out how to hang it over the tank when I get back to work on Monday. I may go with bending a piece of conduit or have the machine shop come up with something. I also dont have a fan on the heatsink the moment. I will test out the heat that these put out and if they get too hot I will pick up a small fan and probably machine it into the heatsink.
