Yeah, my lights slipped down and I guess a bulb was sitting right on it for a few hours during the night...it burned about half of it. Thankfully though, it seems like it's doing good so far.
I really don't know how I can get my temps any further down. I have two intake holes at the bottom that are just freely letting air in. Then I have two 70 CFM PC fans blowing air out into the carbon filters...it was a little cooler without them but it was really starting to stink up my apartment.
