I was nervous about putting my lights in the oven as well. I did 300 degrees for about 18-20 mins with no visible damage at all. I guess the lenses are made for some heat after all they get pretty warm with the bulbs on i'm sure. Now if we could just get someone to release some d@mn projectors we could all quit acting like the Betty Crocker of light fixtures. A pic of my lights is featured in my gallery now.
