Rated 5.0 out of 5.0 Mixed feelings
This product works as expected - it takes about 30 seconds to warm up, but i'm plenty okay doing that for the kitchen.
One concern is the life of these bulbs. In 6 months i have had 2 go out on me. HOWEVER, Philips is actually standing behind these bulbs and sending me refund checks for them. This tells me they expect their product to work and is the only reason i am still buying these. I have received refunds for 2 bulbs so far.
I appreciate Philips for standing behind their product, as i'm not sure other companies do. Since CFLs seem to be hit or miss on lifespan (some are DOA but that's easy to return), i actually recommend these purely because they stand behind them.

Rated 3.0 out of 5.0 by Peter does not last when used frequently with dimmers.
Fairly expensive for a short lasting light bulb.
I use it in the kitchen and light is fine - natural looking color and fairly fast warm up. When used with dimmer it only lasts a few months.
I bought a lot of them and if used in area with infrequent on/off cycle it last a long time.
When used with dimmers and bulbs are switched on and off quite often (most areas of your home) it does not provide any cost savings - bulb cost outweighs electricity cost savings.

I purchased six bulbs for use in exterior (porch) fixtures, that are on dimmers. Aside from the lowest brightness being about 15% of full (not much of an issue) the real problem is that four of the bulbs failed completely within three months. The incandescent bulbs they replaced were between 3 and 6 years old. (This is in a moderate weather area where winter lows are about 50F and summer highs about 90F). The fixtures are fully protected from rain, direct sun, etc.
They may have saved some power, but certainly not money when you compare the purchase price to incandescent.

I purchased 20 of these dimmable cfl's and 18 were defective. Almost every one of them hummed when dimmed even after using special CFL dimmers. After about 10 days the glass bulb started to separate from the ceramic base. Three of them completely came off. Can you imagine these things dropping down from the ceiling and hitting the floor. I have requested Philips to look into the matter and resolve the problem.

Rated 4.0 out of 5.0 by SRA1 At least they actually dim...
I am still searching for that perfect dimmable CFL. I have brand new Lutron Diva CFL dimmers installed, which from what I understand is the best chance to get dimmable CFLs to work properly. Usually the selection is limited due to the size (R40 recessed lights in our house) - then by color of light.
These bulbs may be 2700K color when full on, but they are much whiter light (higher temp color) when dimmed. Right now I have one of these and one incandescent on one switch. The incandescent is extremely yellow when dimmed, while this CFL is whiter and almost pink when dimmed. Unfortunately, we like the yellow much better in our house, but these beat the other 2 "dimmable" CFLs I tried. So far, Sylvania and Neptun "dimmable" bulbs have disappointed with whiter light than acceptable and no dimming noticeable.

Rated 1.0 out of 5.0 by EIEI bad quality product
I purchased four of these yesterday and got it tested today. I put it on low current, the lights were just blinking. I then adjusted it to lowest stable condition(high attenuation) and from time to time, I was flipping the switch or adjusting the attenuation to low. After few hours, it looks like 3 of them burnt itself as when I came back only one of them work.

Have for years been trying to "go green" with use of compact fluorescent bulbs. The longer 2' and 4' tubes are great, however, unfortunately, the elusive quest for the replacement of the small incandescent bulb has not been reached. This particular bulb tends to flicker when on the maximum light setting. Odd, seems like it would flicker when on a minimum setting. (I'm using it with a three way touch switch) Don't know how it will perform with a slide switch or in a non dimming application.

Rated 1.0 out of 5.0 by mdea very very very short lifespan
after 9 months (advertised as lasting 7 years) the light kept going off. never even use the dimmer function. bought/installed 4 and they all went off at once at the same time. luckily I kept the old bulbs and swapped these horrible bulbs back with my old standard r40. they've been going strong for a long time now and still going. don't buy these CFL - garbage.
