Could a older light fixture cause premature CFL light bulb failure?
A few years ago my wife and I bought 8 CFL bulbs to replace the older incandescent bulbs in our master bath. Suddenly [as of the last 2 months] they have began to blow out. Out of the 8 CLF's originally bought we now have 4 bulbs working. It seems as though at least one CFL will burn out a month lately.

I've spoke with the manufacturer and she told me that any CFL that gets used a lot will burn out more quickly, which I said that will happen with about anything but your warranty states that they have a life expectancy of about 7 years. She agreed but told me I had to have my original receipt and the original box, unfortunately I don't so I'm all out of luck there.

Now am wondering if this could be because of the older contractor grade light fixture or that these CFL's have reached their life expectancy?

My CFL's on average last 4-5 years
woops- reread - I thought you said they lasted 8 years

How long is a few years...2....3 years ?

My bathroom CFL's last about 3-4 years

I would say that these bulbs are about 3 years old.

dont think it would be your fixtures. you didn't have problems with the other incandescent lamps burning out prematurely im assuming? and you said these have been in use for 3 years? im leaning towards cheap brand of lamps or bad batch maybe. i would try different brand.making sure they fit snugly in the lamp holder "socket".a loose lamp will cause them to burnout prematurely. if this continues call an electrician to physically check things out. hope this helps..

those lamps usually only last 4 to 5 years if your lucky.

I guess I will be keeping a copy of the receipt and the box just so I can get them replace under the manufacturers warranty next time.

not a bad idea. there's no telling how long they sat on the shelf. who knows but yeah thats not a bad idea. look at it this way, maybe you'll get free replacements for life right? "first time same on you second time shame on them!!"

Yes sir. And to any of the other CFL owners out there keep your receipt and box. Now I'm not to positive on the box but I'd read the warranty just in case. I'm sure you'll need to pack up the burned bulbs ship them in and wait for 3-4 months for reimbursement also.

Read the packaging...mine says lasts up to 9 years...with a small note
Based on 3 hours a day
Ours can be on 6 hours a day...that brings it down to 4.5 years

Here the bulbs are about $1 each
So to ship it to them will likely cost more then a replacement bulb
And actually we had instant coupons here that made the 9w bulbs almost free (.15 tax)
The 13w bulbs would be $1.85 for 4 = .47 each
So check the warranty very carefully, it is probably almost worthless

Are they being turned off and back on a lot? This shortens the life of fluorescents, CFL's included.

It has been said that if a fluorescent light will be needed again within a half hour, don't turn it off.

By on 3 hours a day for 9 year lifetime they mean one continuous stretch of 3 hours each day.

Most of the CFLs I've checked out also state on the box that if they are used in any orientation besides base down the life of the bulb will be less.
