Replacement Dusk to Dawn Photoelectric Switch E185658 120V AC Photocontrol

It has a 0.25" threaded barrel, is RU listed, and is backed by a 1 year warranty. An optional light shield can be purchased to protect the unit from artificially turning the unit off from light coming in from other light fixtures.
It compatible with most LED bulbs (up to 40 watt bulbs or drivers), CFL (up to 39 watts) and incandescents (up to 300 watt) at 120v standard USA voltage.
Optional Glare Shield helps the photocell operate properly when there are other light sources near by that might trigger the photo sensor to think there is ample light available.
