Wondering if I might be better to just go with all Luxeon? I only have 12 of the high current RB right now, and 12 700Ma. I know I need more RB!!! Color too brown/red. Need 4 more Meanwell ELN 48 60D Drivers to complete though. Atleast on my present plan of 3 setups on a 50" tank.

Anyone with exp on Steves sqyare tube heatsinks and Luxeon? I am also controlling through a Apex. so 0-10v control

Heat radiates up....convection helps with cooling.

My preference would be to use C channel with low speed computer fans to help move the air for cooling. Need to think about surface area. The larger the surface area, the better the cooling.

Tubular channel requires "pressure" fans for cooling. Natural convention for cooling plays a smaller role here.

I hope this info helps.
