My fixture is 4 inches above the tank with another inch or so to the water. To lynxvs, the fans push air downward which allows air to flow through and out of the fins.

I've given it some thought an would like an opinion on this. I could add optics to the design but I would have to raise the fixture. So the thought is what if I cut a hole in the canopy for the LEDs and attached the entire fixture to the top of the canopy? I would think this would allow for more spread while using optics and allow the heatsinks to operate more efficiently as they would be pulling outside air instead of recirculating the air inside the canopy.

Any thoughts?
