Can I put my T5HO 2x54w right on the glass cover for the tank rather than raising it on legs? Any reason that's a problem? I'm wondering about the heat?
T5HO light fixture on glass cover?

It would be best to use the legs to prevent heat issues. Too much heat buildup can damage the fixture or bulbs.

Could crack the glass if it gets too hot

I'd be more worried about fire honestly.

Ok thanks. The reason I asked is because the legs didn't fit. Right now it's about 1 inch over it. Is that enough?

Why don't the legs fit?
And inch should be enough to prevent fires/cracking hopefully, but you'll probably still be running really hot. It will decrease the life of the bulbs significantly in addition to limiting output (how bulbs don't work as well).

come get me tang police!
FWIW I have a 3 bulb t5ho fixture sitting right on top of a dual glass top 55g and it doesn't get abnormally hot from what I've seen. Have been running it like this for 3 or 4 months.

I tried this once and the glass definitely cracked overnight and the fixture got really hot.

I got the Odyssea 48" thinking it would fit my 48" tank but it has expendable legs and is actually meant for a longer tank.
I put my hand on the glass after the lights had been on 4 hours and the glass was not at all hot. In fact even the light itself was not that hot so hopefully will be ok?
