The finished product looks GREAT!! Have you taken (can you ?) any heat readings from inside the canopy and more importantly on the top side of the heat-sinks? How much room do you have from the top of the heat-sinks to the canopy lid?

Once i find my temp gun i will let you know.I have about 3 in from heat sink to the top of canopy

Ahh gotcha. That's more than it looks in the picture I was looking at. I was concerned not enough air would be able to flow over the top/back of them which is where the heat from LED concentrates. Sounds like you have it all under control but I'd be interested to see some temps just the same. I don't really have anything to compare them to at the moment but I know the top/back of my LED hood is only a smidgeon above body temp.

Ya i just showed that picture as a reference i hung them with eye bolts inside the canopy.

My temps on the top of the heat sinks are about 91.9

Now you've got me pondering LEDs for myself! :apimp: What are the dimensions of your tank?
