LED light bulbs, as great as they are, all look alike after a while. The same can’t be said for the ZappLight bulb, which also happens to double as a bug zapper. Worried about mosquitoes when you’re out grilling? Screw one into the light socket and you’ll enjoy neutral light while bugs gravitate to the blue UV inner core, meeting their death within. When not in use, the light portion can be shut off while the bug zapper remains live.
