I bought these because the shape and dimensions match my ceiling fan and have high lumens at a low wattage. I'm just looking for brighter LEDs since the ceiling fan is my only light source in this room. Unfortunately, these expectations were not met. They lit up and were relatively bright until you turned on the fan, at which point they dimmed, making an audible buzz and causing a faint strobe. When you set the fan to a high speed, the hum got louder and the fan actually slowed down more slowly than when you actually set it to a low setting. The moment you turned off the fan, the bulbs immediately returned to bright light. Shortly after switching off to take them out, they were still relatively warm. They might work well for you if they're just included in a dimmable fixture with no other features.
