Yeah BR20 looks like.

Those kinds of bulbs usually are R, BR, ER, PAR:

R = Reflector
BR = Bulbous reflector
ER = Ellipsoidal reflector
PAR = Parabolic aluminized reflector

BR seem to be a more wide dispersal while a PAR is more directed I think.

I just replaced all the BR30's in my basement with the Phillips LED ones and they're pretty nice, dim well, and give a ton of light, but I wish the light was more diffuse, the opaque lens on the front doesn't seem very thick and/or the LEDs are quite close behind it, so shadows look sharper and the light is a bit harsher, though that could also be because the lights are noticeably brighter than the bulbs they're replacing.

I tried one CFL one and it didn't last even a year even though it was supposed to be dimmer compatible, but I think there are different kinds of dimmers and maybe the one that they put in when the house was built isn't kind to dimmable CFLs.
