I wanted T-5's for my new 40g b but hear that they run hot. Does anyone down here who runs them have luck without a chiller? The house ac runs at 73 and the tank runs between 74-76. I really want these lights so any help is appreciated!!!

Great point. Right now, the pump only raises the water temp a degree or two, so it's negligible. The tank runs cool without lights, 74-76, so I have some wiggle room.I have always found that pumps seem to put much more heat into tanks than lighting. With Halides yes it was more but I still think it was on par with the heat the pumps put in.
So i guess what I am saying is if you are worried about heat on your tank then take a look at the pumps you are using first.
I think so too. More affordable, less heat, and this tank will never be ultra-low nitrates, so I don't need to worry about lighting many SPS that need different parameters than what I want to run.4 would be plenty .
