I hate their short life spans; I've already toasted around 4 in a year (horizontal mount- ceiling fan with no diffuser or anything (bare bulb)
I've had pretty "good luck" with GE Soft White (2700K) 13w (60w equiv) CFLs.
There is a caveat -
about 3-4 years ago when I started to use CFLs -I bought GE spirals because they were the easiest and most economical to find.
They did burn out much earlier than expected and I was counting the hour rating (8000 hours) not the "5 years" advert.
I phoned the GE 800 number and complained - they asked me to retain the prematurely burnt out bulb and sent me a post-paid container to return it to them, and enclosed a $10 coupon - with which I bought more GE CFLs - I had more bulbs burn out on me earlier than expected - each time GE sent me a $10 coupon - but no longer required me to send any back. So in that way I built up a stock of CFLs since WalMart had packs of 6 for about $10......
All 3 of the earlier burnt out bulbs had a black surround insulation at the base - my more recent ones have a white insulation of which one burnt out prematurely.
I also have older earlier 10w (40w equiv) versions with black insulation of which one is used with an auto timer and is on for about 11 hours/night - and that lasted well over the spec'd 8000 hours before burning out.
I have not had any premature burn outs since then.
So at least with GE CFLs - if they do not last as spec'd - like the earlier black insulation 13w - complaining to GE used to get a $10 coupon - and that gets a pack of 6 CFL's as replacements.......
You might want to try mixing a Soft White (2700K) and a Daylight (6500K)
- combined they seem to give quite a nice light -
but then I like the Soft White (2700K) on their own
- so tastes may differ.
