I hate guesses, so I googled-
It's a green group, but I doubt they could get away with
mis-information for long ;-)
I have a hundred cfl's in use from the original LOA 22w
circlines to the latest 4w mini cfl's. I've had maybe eight
failures and two "catastrophic", a bright flash and that was
all. I marker the year installed, the backdoor 12w U tube
is still running on a 1987 tube, but the 4w mini died in a
year. I'm not including three 13w spirals and two 22w circs
I flat out dropped (broken) over time.
I agree with Don, there are a lot of poorly built
counterfeit cfl's from China at the "junk" dollar stores.
(not the Dolgen and Family Dollar like chains) Even the UL,
ETL, etc marks are counterfeit.
I do return bad products, even the "no returns" junk stores
at least gave store credit for something else.
Manufacturers are very sensitive about bad/poor products.
Usually they already became aware of the problem and have
generous coupon programs to buy redesigned or other products
They really do want happy customers. Dad had a "lifetime
guarantee" pocket lighter he bought during WWII, the
manufacturer replaced it 3 times when it "wore out" during
his lifetime. It pays, he also faithfully bought their other
Unfortunately, the high tech products / services companies
haven't seen the light yet... But if we are willing to
accept some of their crap, shame on us!
