You screw it in, pair it to a device, and stream music to an 8W LED lightbulb. The light socket powers both the speaker and the bulb, so the latter has to be screwed into a socket for the speaker to work.

This is a better lightbulb than it is a speaker. It produces bright and warm-looking 3000K light that resembles the output of a fluorescent tube. It’ll screw into any E27 Edison mount, and we had successful results with three different lamps in the WIRED New York office.
