I used these bulbs to replace a burned out fan bulb. The fit and brightness were perfect for the bulb I was replacing. After a few months of daily use, I put my fan on Away Mode (in which the lights randomly turn off during the day/night to simulate someone being home) for a weekend trip. When I got home and turned off the light, the lightbulb exploded. The bulb's filament was hanging out of the hole made when the bulb exploded, and the fan's glass dome now has a hole through which the bulb's glass broke. I was lucky the glass didn't shoot at me or anyone nearby (or worse). The bulbs definitely work, but the quality is probably not the best.
