Hey quick question i have a 5 inch circle dome light above my marco algea. Its kinda close to my water and scared it may fall in. So my question is if i cut a 1/4 inch piece of the glass i use for my baffle for above it and cut a 5 inch hole in it and set the light on it. Will the light melt the glass? I would even double it up to a half inch if i have to
