The "color" of the light is very warm -- not at all like the greenish-bluish tone one usually associates with fluorescent light. It does take a few seconds for the full intensity of the light to develop at the 29W (150W-equivalent) level, so keep that in mind. It comes on fairly dim, then develops the bright light you expect in about 15 seconds or so.
I'm currently in grad school (an older "non-traditional" student), and I do a LOT of reading. I'd been going through standard 3-way bulbs about one every 3 months or so, so I was looking for a more economical solution. The claim for "7 year life" is based on 4 hours per day of use. I know I use mine a lot more than that (more like 18 hrs or so), so I don't expect 7 years. But if they last more than about 24 months, they'll pay for themselves.
Also, my local discount hardware store charges $22.99 apiece for the exact same bulb, so Amazon's price is a good deal.
UPDATE: It's now March 19, 2010, and I'm still using the SAME 3-way CFLs I wrote about above. One of them is in my living room, where it's in use on the highest setting from around 9:00am until around midnight nearly every day; another one is in the bedroom where it's on from around 5:00pm until around midnight. That's right -- these are the same bulbs I purchased in January 2008, and they're still going strong. They've MORE than paid for themselves. Maybe I lucked out or something (I've read some of the other reviews from folks who've had problems) -- but I'm definitely planning to continue using these, and will be replacing ALL light bulbs in my home with CFLs as the incandescent ones burn out.
The "color" of this lamp is great and most would never guess it's a fluorescent lamp under the shade. But it's using about 1/5 the energy. It's also brighter than most when first turned on (CFL bulbs take a minute or so to reach full brightness).
There are many reviews claiming this lamp flickers, or only worked as a 1-way lamp, or died an early death, etc. While GE might have some quality issues, a more likely cause is 3-way lamp sockets tend to get "fried" from the extreme heat of 3-way incandescent bulbs (which can go up to 150 watts). 3-way bulb sockets also have less area for the added contact needed for 3-way bulbs which makes them more prone to problems. And the high heat, over time, corrodes the contacts in the socket. All this means 3-way lamps are way more likely to have contact problems. This is the fault of the LAMP not the BULB.
CFL lamps, being electronic devices, don't like to be turned on and off hundreds of times a day which is what's happening if you have a bad socket in your lamp that's causing flickering. So yeah, if you have an old lamp, with "fried" contacts, and you screw *any* CFL lamp in, and it flickers, it will probably have a short life span.
So, while I don't know for sure, I suspect many, if not nearly all, of the people complaining about problems with this (and any other 3-way CFL) bulb, have a bad socket in their lamp. CFL lamps, in their early days, had some major reliability problems. But they've been out for a long time now, have long warranties, and the manufactures have generally figured out how to make them reliable to avoid lots of warranty returns.Read more ›
I purchased three individual packs of these bulbs. They do not come in multiple packs. I also purchased the GE 100w replacement Energy Smart, longer life, soft white, multi pack, small size--not three way.
I wanted bulbs for my three-way bedside lamps. These are very expensive bulbs at $16.00 plus tax.
I wanted light bulbs that could be controlled according to my usage. I wanted to have a soft light for slumber and TV viewing, and a brighter setting for reading.
These were the most excellent bulbs in the store as it stated they last for 7.5 years. The package also states that this is based on the 3 hr. per day use.
I bought 3 of these bulbs at around $16.00 plus tax = $51.60
Thus far, I have blown 2 of these bulbs in the last 2 months.
First the low (50) blows then you have to move on to the next strength. Then that also blows and eventually you have nothing left.
There is a warranty but you must include your register receipt and the original UPC container. How many people retain the boxes for bulbs...what a joke.
Easy to install
Short life (1-2 months)
Oversized for most lamps
Mailing fee if defective
Retain original UPC box for warranty
I do not recommend.

Most happy with the bulbs. Could not find them at local retailers.Published 2 days ago by Gary B. Galbraith
This is great! I didn't want a bluish LED hue in my living room, but needed something brighter than the dull yellow light we had. This works fantastic for our living room. Read morePublished 6 days ago by MRN_81
This has a medium base not a narrow tapered one like the incandescent bulbs you may think it replaces. It will not fit all 3-way lamps. Otherwise it is good. Read morePublished 1 month ago by Amazon Customer

I ordered two of these and one failed after about 6 hours of use. Also, it's listed as a 150 W (on HIgh) and the bulb is clearly marked as 125 W. Read morePublished 1 month ago by Bluwtr49
Great bulb for light; however , it's starting to pulsate loudly when it's first turned on. I hope this isn't an indicator of a short life. Will advise.Published 2 months ago by Roger
