With a tank that is 63" long, am I better off going with the 48" dimmable Powermodule or the 60"? Either way, I am thinking about 8-bulbs.
Are you wanting to go with the 48" purely for the dimmable feature? Personally, I would go with the 60" fixture. I don't dim my T5 as I believe it shortens the bulb life. I have two 48" fixtures over my 96" long tank.
I know ATI tells you not point the vents towards each other because it will cause heating issues.
I'm not sure what your setup is like, but if you can add a small fan to get air movement between the two fixtures I think it would be fine.
Thanks for the feedback. I decided not to point the vents towards each other. There is a 4-5" gap between the fixtures due to the power cord being so darn thick but it looks perfectly fine.
I have the fixture pretty high off the water line right now to acclimate the corals to the new light. Previous setup was 4 AI Vega color which only gave me 300 par at the water line, 150 par mid tank and 80-90ish par on the sand bad.
The ATI fixtures really are par monsters!!
