Do your Compact Fluorescent bulbs (the curly ones) last 9000 hours?

Mine sure don’t.
I don’t have many in my house, but I have had to replace 9 already. They are in normal sockets not dimmers.
Some of the bulbs say they will last 12,000 hours. Others say only 8000 and they estimate 4 hours of use per day. I don’t use my lights anywhere near that. However, in 3 years I have had 9 stop working.

Are you aware that there is a Limited Warranty that states:
“If this bulb does not last 5 years , return UPC and register receipt along with your name and address to XYZ Consumer and Industrial Product Service Department, .... XYZ company will replace your bulb.”?
I never noticed that.
From this day forward I will write a number on the bulb as well as the UPC and receipt and put them in the storage container where I keep bulbs. If it pops I will be sure to get my replacement.
I figure the bulb manufacturers have no incentive to improve if we don’t complain. These Made in China bulbs are going to be mandated for everyone soon. Let’s make sure they have the quality they advertise.
What do you think?
