This includes a light sensor that automatically turns the lights on and off. There's a switch inside the garage to disable the light entirely; when it's on, the light is controlled by the sensor. And these bulbs are very bright, which is good.
There were some hitches with the initial installation — nothing dangerous; just annoying, requiring tracing lines back through fixtures to figure out where the missing connection was. When, after a couple of false starts, Lisa threw the master circuit breaker and we waited for the light to come on (she'd covered the sensor with a glove to simulate night), we were on tenterhooks until, after about 90 seconds, everything worked. (The sensor has a time delay so that it doesn't come on and off with every passing cloud during the day or car with badly-pointed headlights at night.) This is a nice improvement that will reduce the amount of bumbling around in the dark when we park at the south end, as there are no streetlights on that block.
