the light bulbs in our garage keep burning out.  the builder said that it's common because of the vibration of the garage door opener, but it's irritating as h---.  I've swapped out pretty much every bulb in the house to a cfl but I wasn't sure how well they'll work in a garage in the cold of winter.  Anyone using them in garages?

Yes, I've used the 100w equivalents for years.  They don't last as long as when they're inside but it's still better than replacing an incandescent bulb every 3 months. 

some cfl's do alot better then others. I think the energy star rated ones have to perform in cold start up mode to be qualified.
In 18 months, I have had 1 cfl die. It was an outside light that got used every day. Most of My CFLs are pin based ones not screw in ones.

cheers,

CFLs also have filaments that can be damaged by vibration, but they're far more robust than incandescent filiaments (they're run at much lower temps, and are much fatter than incandescent filaments, but are necessary to keep the strike voltage low enough.) Warmup to full brightness can be quite long when it's well below freezing. That said, I have 19W CFL floods (roughly equivalent to a 75Wcandescent R30) in the overheads and a 13W twisty in the garage door opener's internal fixture, and they've lasted for at least 3 years, still going fine, but I don't cycle them too often- maybe once/day on average in winter.

LEDs have the edge from a vibe-hardness and instant-on point of view, but those with decent color-rendering aren't available in higher-luminosity versions.

I use CFL in the garage and CCFL outside (that are on every night).

I use CCFL on the front porch- with no filaments to burn out they'll last forever, but when its in negative single digits F the ramp to full bright is incredibly long. At mere 30F it's still a few minutes, but far better in summer than winter.

jerkylips the CFL has been in my door opener for about 6 years, you could try bracing the opener better to eliminate vibration

There are incandescents that are built for  rough service that will last a lot longer.  something for a ceiling fan is also tougher. Another option is to use another light as the door opener light. You get a bulb to 2 prong adapter and then a light that you can mount somewhere and run the plug to it.
A cfl for outdoors lights will start and brighten much quicker than standard also but if the vibration will kill them within a year, I don't recommend them due to the hazardous waste situation. Since a garage door light is on for such a short time,  it is a place where it doesn't pay to use them.
