I don't know. I like this bulb very much just as it is, for its brightness and its trueness to colors, which most long-life bulbs do not offer (they distort reds, blues and can appear dim or grim.) I hope they don't change this item; it's nice to know that I can source it at Home Depot and should be buying another one in the near future.
Yes.
Front glass warm but the base will burn bad.
Yes. You will need the right fixture for the bulbs.
The box says it is dimmable.
A Halogen lamp rated for 130V, can be replaced by a Halogen lamp rated for 120V as long as the main supply voltage is 120V. You will get a bit less light than that of a 130V, but the lamp will work okay. If the mains voltage is 130V and you use a 120V lamp, the lamp life will be reduced. Other than that, the lamp will work okay.
Yes - However I found the lamination was not the same - I have two outside systems one with the older incandescent bulbs (120 w) you can notice the difference with both the shadow and ability to see a nickel on the ground
Performs the same in my opinion in the security light I have them installed in. 1. Just as bright in my opinion, operates the same. 2. No, instant on just like an incandescent.
