Very good replacement, if anything it might be a brighter bulb than the one your replacing
Thank you for your question. This bulb is not outdoor weatherproof rated, but is dame rated and can be used outdoors in protected environments/fixtures that protect the bulb from direct weather/rain/moisture.
Yes there are about a dozen or so LED's on the bottom of the bulb and they do a good job a lighting directly under the bulb.
Thank you for your question. Yes, this light bulb can be used in an enclosed fixture.
I have had the bulb for over 2 years and have never noticed any heat coming from it.
It does not fit into an exterior fixture even though the advertisement shows that it does
You need to remove the ballast that powered the old-style light, this light is wired directly to 110.
It fits in the standard screw on slot however, it is a million times more bright.
My store carries them, check with your local store.
