T5 lamps operate at 95 degrees. That is the optimal operating temp to get the best light efficacy. your fixture probably has a built in heat sink to help dissipate heat. DIY fixtures to not have metal heatsinks and must be cooled at the ends to produce the most efficient light. so you do have heat, its just being dealt with more efficiently.

i am going to need you to explain this because i dont understand.

My t-5 fixture puts out NO heat, i mean like NONE. You can touch the top of the fixture after running for 10 hours and its room temp . Not to mention my tank stay at 77-78 all year around with my house temp at 75.

What kind of t-5 did/do you have? i have noticed PC's to get hot and on my biocube they keep my temp at 80

That is precisely why I built my light rack out of aluminum "C" channel. It makes a great heat sink.

Sorry to hear about your tank. I certainly understand how you feel.
My 450 tank crash completely (like everything dead) a few years ago when some worker shut off the electricity to the chiller (outside) when they work on electricity and did not turn it back on for the day. My tank go from 83 peak to 96 when I was home that night. The chiller was on a 220 circuit by itself. They did not even work on that circuit.
In large system like that, there is very little you can do once it start to crash. Doing a 200 g water change is like spitting into the wind.
I do have some very colorful SPS that you can frag from when you start to stock it again.

All the energy used by any device (pump, heater, light, chiller (yes chiller)) will end up as heat. MH, PC, T5 does not matter that much. If you put 400 W into the ballast, light and heat will come out and light will eventually end up as heat. Reefers just move the heat from one place to another by various devices that we have in our tank.

I agree with Minh and sometimes we don't a good enough job...lol

Thanks for the offer Minh, I might take you up on it.
