For several years I used these bulbs in a bathroom fitting until I discovered LED bulbs do exactly the same thing but without the heat. I used these bulbs for a glass fitting according to the manufacturers specs and it was a disaster. The cover glass cracked twice and the burn marks spoiled the fitting. Now I use LED which are just great.
