You say that you get less service life than you would expect from regular incandescent lamps? Did you determine why this is the case?

A good start would be to go into your lighting panel and tighten down all the connections, with the power off of course. Tape up the screwdriver when doing the main connections.

No, I think it's more a matter of brand/manufacturer.  We've got the Computer / Radio / Sewing room here, with two identical fan/lamp things on the ceiling.  Noisy buzzers from Home Depot (don't get me started!).  Regular incandescent lamps don't last.  "Fan" or "Appliance" type lamps are better, but still succumb to the vibration.  We tried to replace the Fan-type with some round globe-type CFLs, no-name from the local hardware store, mostly to bring the heat down.  They lasted less than the Fan ones did.  Replaced some of them with the "Curly Fries" type from GE, I think, and they're still going strong.

So, it's not the position (all are base-up), not the voltage (same circuit), not the ambient environment (same room).  What's left?

p.s. Neither brand gave me any problems with interference on HF...

  I have a sneaking suspicion that the random failures reported may have to do with the semiconductor ballast in the base being unable to tolerate massive voltage surges on the power line, especially in areas that get lots of thunderstorm activity and lightning hits on power lines.

  It seems that most of the complaints in this thread are from people living in areas that get "real weather".   Here in southern Cal, where Johnny Carson once quipped " I can't understand why TV weatherman here are such celebrities. There is no weather in Los Angeles -- just differing degrees of air quality",  we practically never get thunderstorms and lightning.     And I have practically never have heard of early CFL failures around here either.
