Either the CFLs are getting too hot even for a 105 C or 113 C part, or they are low-quality products without the special high-temperature electrolytic capacitor. If you get early failures like that with major brand lamps, send them back to the manufacturer. They can tell how long the lamps have been running, so you shouldn't have to prove anything. -- Regards, John Woodgate, OOO - Own Opinions Only. The good news is that nothing is compulsory.
