Anyone know of a photocell light adapter (to implement dusk-to-dawn on/off on an existing light fixture) that doesn't cut the light output of the bulb (at least not significantly)?
I've tried these screw-in adapters from the hardware stores and they work, but they bring the light output of a 100-watt bulb down to about that of a
60-watt bulb (or maybe even less). I've tried using a 150-watt utility bulb and that didn't make any difference.
