A great replacement bulb that fit perfectly.
This was a replacement for a bulb that went out. It works well, it’s very bright and now I can see better in my den area. It fit perfectly and was very easy to install.

Absolute Trash - Dead on arrival 2 times in a row
I ordered this replacement bulb and it did not work. After requesting a second replacement, it arrived today and didn't work either. This one fit a lot more snug and part of my lamp snapped trying to remove it.

Nicely packed, and fits into my floor standing lamp
My GE floor lamp socket is keyed, and this lamp bulb is not, as shown in the pictures. But it will fit and works wonderfully. It has saved this crazy lamp socket and lamp from the trash. The light is bright - daylight bright, not soft white, and is just what I wanted. This bulb is packed in foam, front and back, then in a cardboard box, the Amazon had it in a larger box with airbag cushioning. I felt very confident that there would be no damage, and there wasn't.

Works on my floor lamp
My floor lamp came with a double circular bulb with the same 4 pin base. The diameter was about 9 inches. This 8x8 square fits fine due to the rounded corners and is plenty bright and nice warm daylight color. Only con is relatively expensive but it should last several years and cheaper than even the cheapest new floor lamp and less waste to boot. Will probably buy a couple more before this one goes out of production. The circular ones are no longer being made.

I thrifted a lamp that asked 38 w 2d which they do not make anymore. I couldn’t find that exact bulb so I purchased this one. And it seems to work. It is bring and fluorescent white. But so far so good

Perfect fit
I really like that when I turn on the light, it doesn’t have to slowly warm up to the actual brightness, it’s just bright! No more waiting in the kitchen on dark mornings for the light to warm up and be bright.
