This bulb fits snugly in my bathroom vent but takes a few seconds to turn on. An uncomfortably bright flickering when entering the bathroom in the dark. As far as I can remember, other CFLs I've bought over the past few years don't flicker, although I've been exclusively buying LEDs for at least a year. Otherwise everything is fine: lots of light and a nice warm color.
