I built my own DIY LED fixtures, I should probably make a thread too. I wish I knew how to weld, and made my own heat sinks.... I am jealose of your heatsink! The cheapest I could find was still expensive and not custom to my tank (heatsinksusa.com just in case anyone was curious.

I was in Ocean Creations in Calgary a while back and they have a tank that has some LED T5 bulb over it, including a green and red. The guy working showed me the difference with them on vs. off and the colors where out of this world. Mine will be both on separate channels so I can dim them right down to 5 - 10% if I need to.

And most Rona's carry the 1/8" cast clear for a good price. |
That what I was thinking as well to use the cast acrylic vs. the extruded. I can get it at Totem as well but will check our local Rona to see if there price is better.
