A lot of the reviews for this lamp (bulb) are unfairly giving it a poor review: it says how large it is right in the description, it says how bright it is in the description, it says its lumens and color temperature right in the description, so don't give it a 1-star review for not reading the description.

Anyways, the bulb works, plug it into any socket that's rated 60watts or higher, and you now have a 150-watt equivalent. I will agree with others that this is a huge bulb, most fixtures it will not fit in, so make sure you take the time to measure correctly. For my intended application I was putting it in our living room, which only has a floor fixture; after installation, it was about 1/2in too tall and you could see it over the glass bowl, but that wasn't the real problem. It really was just too bright, and I wound up bringing out a second light fixture and having 2 100-watt equivalent bulbs instead, nicely balances out the room.

The color temperature is for the most part what I was looking for, 2700K, which is the incandescent equivalent, so common for "relaxed" rooms (living rooms, bedrooms, etc). Trust me, you don't want to get a cool-white (commonly 3400K-5000K) or daylight (5000K-6500K) unless you really know you want a blue/green-ish hue in a stark-contrast room (workshops, offices, and plant growers should know their respective light spectrums). This bulb has a fairly poor spectrum rendering, you can tell its not quite the same range as an incandescent (CRI -Color Rendering Index- not being all that helpful to begin with, but everyone has a very slight orange-green hue with this bulb); it's perfectly fine for home-use, just relevant for video/photography or people who are really picky.

I have not had an issue unlike the other reviewers here. At the time of this writing, my GE bulb has been used in a floor lamp for about three and a half months. It goes on almost every night. The bulb has been great for me since it allows me to add a lot more light to the room while using much less power than an incandescent 100 W bulb. Please be aware that it's quite a bit larger and more than an inch taller than a regular CFL bulb.

The former USA made GE 150W CFL, which this unit replaced, lasted a month shy of 4 years, according to my records. This replacement GE CFL, made in China, only lasted 4½ months in the same fixture and daily useage.

Additionally, slowly rotating the failed CFL side to side I can hear a pronounced clunking sound coming from the ballast housing which I judge to mean that the whole assembly has broken loose from its internal mounting points.

I suspect the manufacturer is using inferior or gray market parts in the ballast and sub-standard manufacturing processes and materials to save cost. Doing this has resulted in an inferior product.

Because of their high reliability I've always purchased GE lighting products so I'm very disappointed that this GE CFL failed so quickly.

I purchased this CFL directly from Amazon but they won't replace it, requiring me instead to contact GE for a warranty replacement, adding time to mail the UPC and sales receipt to GE's Product Service Department, which will take at least a month before I have a new CFL.

P.S. After posting the initial review Amazon reversed course and replaced the failed CFL, including 2-day shipping, at no cost.

Was initially very excited about being able to switch my incandescent light bulb with a CFL in order to save energy. Unfortunately I've purchased two GE 150w equivalent CFL bulbs and both have burned out within a few weeks of installing. I have had success with others with less light output but these seems to have an issue. Clearly not buying these again.

Oct 2011. The package says to install base up - but it wasn't easy to find that important information.

My comment to GE Electric is that there is important information mixed in with all the verbiage along the edges of the product package (the colorful sheet inserted into the plastic molded package). It is an expensive light bulb so please work more on the package information. I didn't see a visual aid to show how to install the bulb.

I own at least 7 of these in service now, 6 are sideways for about a year before I noticed that was "wrong".

Nice bright bulb. :)

The bulb takes tens of seconds to come to full brightness, but is at 75% or so of brightness right away. Color temperature is quite warm, close to incandescent. Note that the bulb is physically large (check those dimensions to see if it'll fit!).

I had my fingers crossed hoping that it was only the unlucky ones whose negative reviews dominated the evaluation of this product. Well, they were right. I bought two of these 150 watt equivalent CFLs for use in a large 15 inch enclosed glass globe under my patio. The first one was great while it lasted which was 7 days. Perhaps these bulbs don't like to be in an enclosure. I'm going to try the 2nd one in an open fixture in my garage. I suspect that there is a very good reason why these bulb are hard to find... they don't last.
