I bet it will get really hot.
I would try ti get it at least a few niches off.

It will overheat the light itself, raise it off.

dorry54 · 10/09/2017, 12:04 PM

it will look better raised up more shimmer but not a good idea on glass

Almost all the heat is radiated out the back (top)...and sides.
LEd's produce little "infrared" in the photon stream soo doubt it will be a problem.. though Not recommended for a number of reasons including a "maybe" w/ cooling..
That said I'd recommend an air gap for ANY light..just because..

turn it on and feel the front.............

I see no reason for it to be a problem. Light cools through slots on the side, so no overheating issue there. Glass will get hot, though no more so than with a MH hung over it.

No worries about lens overheating, discoloring and or cracking at all? I wouldn't take the chance that lens gets pretty warm as is.

I've got a pair of 160s sitting directly on 1/4" plate glass. No observable difference versus the ones that aren't. LED don't radiate heat like other light sources (infrared mostly). Is it better to hang them clear .... Probably. But I see no major issues putting them directly on glass frankly. I guess time will tell. Maybe ask Kessil.

I don’t know how hot the glass of the a360s get, but I know the AP700s get hot enough to smolder and burn through towels and jeans such that the glass over the LEDs can get coated in brown soot from the inside!

I have four marsaqua boxes on my glass lid. No problem at all. I don't know how weights compare. I don't know how heat output varies though.

still considering the lensing/design ect why one wants it right on the glass is questionable..

anyways for fun:
