Wait so your problem is with the heat going to the water? Or the light itself overheating? Sorry for the noob question here

Fluorescent lighting

I am worried about the lit creating too much heat in the water.
It's a moot point now. I bought a 4' fluorescent with dual 6500K bulbs and a built in reflector. I will see how it goes, but if it gets too hot, I will buy a fan that I can screw in place to help keep the temp down. Light looks good so far. Thinking of upgrading the bulbs to 10000K bulbs to brighten the ends more.

Right now Im using a lamp like yours in my 20 gal and 75. In my experience, it does make the water a little warm but not too much to cause a problem. Although I didnt notice any difference to the temp in the 75 except for on the water surface. I actually like the added heat, kinda replicates day time more. But if you really dont like the temps to be affected, yea you should probably buy a fan of some sort. Or maybe drill some holes through your canopy? Goodluck with your lights, man.

90% of the heat from florescent lamps comes from the ballast. On my old setup (I have since switched to CREE LEDs) I used Four 4' florescent tubes and mounted the ballast below the tank in the stand. The lamps by themselves get warm, but don't really give off enough heat to warm up the water.
You could do it by taking the ballast out of the fixture and lengthening all of the wires. I did it by building the light from scratch, I bought a stand alone ballast and stand alone florescent lamp sockets. Cost me $30 + the cost of the lamps (already had spares from other lights in my house).
In any case, its probably not a big deal. Your pumps/filters probably heat the water as much or more than the lights do.

I am noticing the light doesn't seem to heat up that much. I can feel a difference in the air temp around the light after it has been running for 30+ minutes, but the water seems just fine and the light cools off very quickly.
Thanks for the feedback. It was actually very helpful.
