Innovative Marine ChaetoMax light heat question?

[Fishcrisp]

I have a Innovative Marine nuvo 20 and im thinking of growing chaeto in the back. I was looking at IM chaetomax light. My concern is the glass cracking with the heat that the light is going to produce or am i just being paranoid?

Your being paranoid. I have one, it works great. It comes with 2 thin sticky velcro strips(one for each long side) that stick to the glass of your aquarium/refugium. Here's a picture of my Figi Cube refugium on my Nuvo 20.
