Yeah, I remember my very first spiral that I bought, it was an LOA some wattage, I really liked that one, and it lasted it's rated life, burning out by the tube not the electronics! I really should have bought more, because I can't find them anymore!

Go with Feit Electric. They're good from what I hear around here. My bathrooms got them over the mirror. They have been used daily for months and they haven't even grayed at the electrode ends. (None I can see though) I think those (Feit Electric) will last a long time maybe beyond that. They're the lifeguard/bonusline of the CFLs.

Yes. I've had a Feit lamp in use constantly lit in the kitchen, and it lasted a little over it's rated life, when it died it just glowed at the heavily blackened ends. I dropped it off for recycling...
