Wondering if any one knows : 1 how hot the glass and fixture gets for one of those metal Halid type fixutures ( the ones in gyms).. and is it possible to place a sheet of diffusion gel on the glass at t he bottom if I can anchor it down. 2 If not then is there a FP frost or any other product that can be sprayed on the oustide of the glass. Reason for this is to calm the fixture down and spread light somewhat thanks
