hydrofarm grow lights, ballast, reflector

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.

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. :)

I have a lamp where I use a 150 watt bulb. I know that's a lot, but the lamp is built for it and I need a lot of light there. I didn't realize they made a T4 bulb with a 150 Watt equivalent. When I read the bullets, especially "Guaranteed to last 8 years based on 4 hours use per day at 120V" I thought, why not try it. My 150 bulbs usually only last a few months. This could be cool. So I ordered one. Just to see. I saw. It lasted 8 days. And I seldom had it on more than four hours a day.

Don't waste your money. It's too bad too, because it really did seem the equivalent of a 150 Watt bulb.
