I don't know how you pick good quality dimmers as recommended on the box, but these bulbs work great with my dimmers. I deducted one star because I've had a couple of bulbs burn out way too soon, but the rest have never been changed and are still working great.

The cfl's are dimmable with most modern dimmers, built after 1995. The best way to use these lamps are to install them and run them for about 1 hour at 100% to set them properly, and not to mix different size lamps on the same dimmer circuit, nor to expect much less the 30% as the lowest setting. As the newer and more expensive units come to market, they will dim down to nearly 10% of full brightness. I like the idea of reducing energy waste, and when LED lighting gets going that will be much more cost saving, but right now LED's do not dim at all, but do last in excess of 50,000 hours. I am an electrician with over 42 years experience at my trade, and I still have a few regular incandescent lamps in my home, in the dining room for special situations, with a heavy duty and old Lutron dimmer. As my 25 watt lamps burn out, I replace them with 10 watt units, and as the fixture has 2 dozen lamps, nobody really notices or misses much.

They are bright, but they do not work in my dimmers. They go out when you try to dim them. Oh, well, they are cheap

US fairlytales sold me these cfl bulbs. Bulbs lasted for a short time if they worked at all. US FAIRLYTAILS DID NOTHING TO HELP WITH THIS PROBLEM.
** Oh well I feel these balbs are cheap.

With minimal to regular use, all of these bulbs burned out within a few months. They have a very short life.

Waste of good money. In less than nine months three of these bulbs already died. We used them for a couple of hours in the evening during the week and a bit longer on weekends. They didn't come close to the thousands of hours advertised.

This brand of CFL bulbs is junk. Bought a couple dozen about a year ago and put them in every light in my house (both dimmable and non-dimmable fixtures). Like clockwork, wherever I put them in, they are starting to burn out. These things ARE NOT DIMMABLE. Within a week I went through 4 bulbs in a 2 bulb dimmable fixture. I have regular incandescent dimmable bulbs now and they work fine.

The manufacturer says they have a warrantee and are willing to stand by product, however factoring my cost of shipping to replace lousy light bulbs makes it not worth it. Especially since they will most likely only last a year.

And although I'd just assume toss them in the trash, I do want to do the right thing w/ spent CFL bulbs. Im not making a trip a week to the local CFL recycling location. So I have a box of a dozen blown CFL bulbs in the basement I am saving up.

Bite the bullet and buy name brand CFL bulbs. Save some cash and look online or the local warehouse club. But avoid ULA brand bulbs.

It appears that there is only one actual type of dimmable 23W CFL from China, and they all have very high failure rates, 6000 hour "warranty".

These have been released as "Greenlite", "Harmony" and as "U Lighting America". They have their own "UL" logo to make it look like they're UL listed.

Overall, myself and others included, there is a 50% failure rate on these bulbs within 3 days. I couldn't get warranty on mine that failed the day they were installed. The company's website just lists the bulb information, but there's on contact information. The phone number for warranty is an answering machine with an old lady saying you've reached U Lighting America, leave a message. Several other people have been told that warranty is only good when purchased in California for use in California.

The seller also wouldn't take them back as DoA without negative feedback. Even then, I'm waiting to see.

For most of those that work, the light is crisp white and very bright at full power. As you turn the dimmer down, the light stays the same for about 30%, but the bulbs begin to hum. Past that point, they begin to dim. Past 50%, they flicker. Past 70%, some of them extinguish, or pulsate off and on with substantial buzzing.

For one of them, the light was markedly more pink, but otherwise operated the same way as the others.

So basically, avoid these bulbs. Go for the Sylvania, Earthmate or GE brands with good reviews.
