A: YES. THIS WORKS INSIDE AND OUTSIDE. IF YOU WANT A DIMMER LIGHT INSIDE, THIS IS FOR YOU.
A: I wouldn't think so, more a outside bug light
A: You can absolutely use these indoors. This bulb does produce a yellow light, however. If you are looking for a less intense light, I would also recommend taking a look at bulbs that produce lower amounts of lumens, Such as a 40 watt or even 25W A19.
A: don't know write Home depot , sorry
A: Not sure.
A: All I saw was 60 at my local HD. Book looking for bug bulbs for a wile now. May be forced to buy LED now.
A: No we do not sell a 40 watt bug light bulb.
