I have had every brand made, I think. Sylvania,Phillips, GE, Globe, and a miriad of brands I have never seen before. I am not sure which ones had problems. I have had some DOA units too in 6-packs. I have had units that took 5 minutes to brighten so you could tell they were on when I lived on solar power, on cold days.
I sell old units to Jewish people for weddings. Nobody knows it isn't a wine glass breaking inside the bag...LOL
What brand are you buying? I've had a bunch of Sylvania and Feit CFLs burn out -- but I've had Sylvania incandescents that lasted only a day or less too.
