Help with adding T5 fixtures

[razzpatazzz]

So I bought this T5 fixture when I started the hobby but ended up going with LEDs. I've been considering switching to or adding T5s because I like the look of it a lot more but I was wondering if this fixture was even safe to put on a tank? It attaches via 2 foots that go on the side panels and I have 1/4 low iron glass I believe. Not sure if it's okay to put this much weight on the glass? Otherwise I was wondering if There are T5 fixtures or retrofit T5 fixtures that doesn't have to be hanged from the ceiling but in some other form, thanks in advanced.
