I didn't realize they were bigger until I started swapping them out in my dining room. They almost didn't fit, they were so big. I had to bend one of the holders a bit to keep the bulb from touching the metal frame of the lamp. They're pretty headstrong. You need to replace the blown bulb with an identical one or replace all of them. I have them on my dimmer. They don't say they're dimmable, but I dimmed them just fine. Photos are attached. I am happy with these pears.
