wall light. My home in Florida is the same as many there - deep awnings outside and windows that keep out the hot, muggy sun. So during the day it can be (totally) DARK in DR and PR. They're white enough to look like daylight indoors and are acceptable when dimmed in the evening (I use them with chandelier lampshades so they're not so "blue"). Yes the observation in other reviews is correct - they are threaded on the ends The sockets are a bit longer as are their collars so they are visible compared to incandescent bulbs but doesn't bother me as they have shadows.
