I've installed them in outdoor fixtures with serif glass top pillars and they work as expected - turn on at dusk, turn off at dawn, usually within a minute or two then another light source. Lights with built-in sensors from dusk to dawn. I was concerned that the light output would be weak through the glass in the fixture, but that's okay. Gives a lot of light without being blind at night. They appear to be well built and we are happy with them so far.
