A: Thank you for your question ,these bulbs can be used outside as long as they are covered and not pointed directly at a wet area, as they are suitable for damp location
A: Thank you for the question. No do not remove the rubber base. That is there to prevent any type of shock.
A: Bright white has more blue in it, soft white has more yellow light.
A: I'm not sure of the difference. I chose soft white because I'm using in the dining room chandelier and don't have a dimmer switch. I'm happy with the soft white in this application, but plan on installing the dimmer for the light control available with this bulb.
A: Thank you for the question. Soft white is 2700k which is a yellowish color. Bright white is 3000k. Which is yellowish but has a little white in it.
A: Bright is brighter. Soft is softer.
A: Not likely. These are more "decorative" grade bulbs and likely cannot handle outdoor weather. Unless, the packaging explicitly says that it's safe for outdoors, I wouldn't use them outdoors.
A: I just saw on the specs that it shows "indoor" only
A: Yes, there should be no issues.
A: Ours are outdoors in a lantern-type fixture, under a wide overhang.
