Thanks! Good luck with you build.
I am ready to move on to phase two, which involves adding a strip of LED's to my existing T5HO fixture for my saltwater tank.
This is what I am thinking of doing:
I think that square aluminum tubing should be good for a heatsink...something like this:
I can screw the struts to the side of the fixture and then I just need to find a way to attach the heatsink to the struts so that it can rotate. This will allow me to 'point' my leds where I want them depending on the height of the fixture.
I am going to wander around lowes today looking for some inspiration but if anyone has any ideas please share!
