E12 2.5W T3

I was pleasantly surprised by the light output from these tiny bulbs—250 lumens is plenty for my hallway fixture. They warm up instantly and have a nice, soft glow that's easy on the eyes.

Swapped out the old 20w incandescents in my chandelier for these and the brightness is basically identical, which surprised me. The E12 base screwed right in and they barely get warm even after being on all evening.

For such a tiny bulb, the light output is genuinely close to my old 20-watt incandescent, and it stays cool to the touch. It's been running in my fixture every night for a week without a flicker.
