Just last weekend I discovered that I had four burned-out CFL bulbs in the house. Then this morning another one. I thought these things were supposed to last longer than regular incandescent. Or perhaps they're being made cheaper and cheaper, to the point there's no real economic benefit? Mine are bought at either Lowe's or IKEA. Any other experience out there?
I had a problem initially but it was because I was using them on a dimmer switch (even though it was normally at full power). I changed the switch and then it's been fine. Maybe you have a lot of power fluctuations?
Interestingly, these weren't. Guess I'll need to start making notes of brand, lifetime, etc. etc. to see if any patterns emerge. I have some LEDs now, and like them much better.
We have had a couple go out in the last three years. Both were in enclosed fixtures. All of ours came from Lowe's. I too like the LED ones more
Right now we just have a few that are used mainly as hallway lights. They're plugged into the wall and have sensors that automatically turn on when it gets dark. We bought this set at Costco five years ago and they're still working like brand new. They can even change colors based on setting. We also have one version that is a flashlight which you can leave inside a holder that is plugged into a wall to keep it charged when not in use. This one also has flashing capability. We place it in one of the hallways as it's proved quite handy at night as well as during power outages which occur quite often during storm season. Outdoors we have a bunch of solar powered ones that died after one season. Kind of a bummer, actually.
Just as driving 'normal' cars gives us bad habits for a Prius, so can CFLs suffer from incandescent habits. CFLs are poor choices for locations that turn on and off a lot, but my mother taught me to ALWAYS turn out all the lights when I leave a room. "The life of a CFL is significantly shorter if it is turned on and off frequently: In the case of a 5-minute on/off cycle the lifespan of a CFL can be up to 85% shorter" - Wikipedia If you will be back within 15 minutes, leave your CFLs on. (if you can) CFLs are not typically suitable for cold weather or outdoor use.
I had the same problem until I switched from the Sylvania and Bright Light bulbs I had purchased from Lowes and went to the GE bulbs. The GE's seem to last forever, at least for me.
The Ikea bulbs are pretty poor quality in my experience, especially given how relatively expensive they are.
I have had zero issues with them so far. It took awhile to get used the them warming up but, Now it's no big deal. I've got them in every lamp or fixture in the house.
We use a lot of CFLs, and it seems like they don't last any longer than standard incandescent...but I'll admit to buying cheap ones from Sam's Club and Walmart and haven't really kept track of exact ages (though definately all have lasted far under the alleged 5 years they claim).
I can't speak to their quality, but their CFLs definitely aren't great on the price scale. I don't have THAT many years experience w/CFLs but have only had one fail so far. I had it a timer that would turn it on/off several times a day, everyday. It was bought from Lowe's and might've been one of their store brands. I didn't care though. I knew the cycles would shorten its life and the bulbs were free after rebate anyway.
I have experienced this a few times, i usually figure they were bad bulbs. It mostly happens when i place them on a dimmer switch. My porch light seems to burn through incandescent bulbs every month, so i put a CFL out there. It's a motion sensor circuit, so i think it will kill the life, but i'll be damned if i'm gonna waste my time changing an incandescent every month. so far the CFL has lasted 6 months, we'll see how much longer
I've had mixed results. Some of the early ones we bought failed quickly. On the other hand, I have one over our kitchen table that has been running for ten years, and it gets used more than any light in the house. From my experience, CFLs are an area where brand makes a big difference. Some are a lot better than others. Tom
Would be nice to have comparative test results of different brands. Meanwhile, for what it's worth: Compact Fluorescent FAQs
I bought a batch of CFLs from Home Depot back in 2000 (~$25 each!) and put them in the kitchen ceiling light fixtures. So far only one burnt out. Later there was a coupon from the utility company for a specific brand, I think "American something", don't remember exactly, those all burnt out in just one year. More recently I bought a bunch from a wholesale store and so far so good (only used 1 ~ 2 years).
