THIS LIGHT FOR BROAN STOVE FAN AND IS A FACTORY REPLACEMENT. I HAD THREE AND NONE LASTED MORE THAN 90 DAYS. LAST 33 DAYS, JUST BEYOND THE WARRANTY WINDOW AND ACTUALLY FALLING (UV LENS RELEASING), BULBS ARE NOT ENERGY EFFICIENT AND NOTICEABLY HOT. I SWITCHED TO PHILIPS LED LIGHTING, WITH VERY EFFICIENCY AND VERY NO HEAT EMISSION.
