This bulb is BIG. The screw is normal, but it fans out to 9 inches, so it won't fit in a lot of indoor spotlight fixtures. Other than that, it's your standard fluorescent, with the usual advantages: it won't overheat, doesn't need much electricity, and lasts a long time.
Would not fit in recessed fixtures:
These bulbs would not fit in the recessed fixtures (cans) in my house because of the large plastic housing near the base of the bulb.
Dim...:
I ordered this product to try and at least make some parts of our business environmentally friendly, but when we put this bulb in to use it didn't nearly produce the same amount of light as a regular 100 watt flood light. Two weeks later I purchased the old fashioned flood lights.
This item is a joke.:
These bulbs burn out every 2 weeks, I am tired of replacing them and went back to old style.
