Customer Reviews
Just want folks to be aware that these measure approximately 6.5" in length, or about an inch longer than a typical-sized incandescent bulb (like 60 or 100 W variety). I was interested in getting one of these to replace the 50/100/150 W incandescent bulb in my living room lamp (the tall, free-standing kind), but found it to be too long as it comes out of the top by about an inch. For now I am waiting for a company to come out with a CFL 50/100/150 equivalent that matches up in size better.
Ok, the short version is this lamp works great. The main concern is if it will fit in your lamp, so check the dimensions carefully.
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.
So before you screw an expensive bulb into your 3-way lamp, you might want to unplug it and use a pencil eraser to clean the 2 contacts at the bottom of the lamp socket just to be safe (unless it's a brand new lamp). The contacts should be bright and shiny. If they're discolored, dark, etc. you may have a problem.
