Customer Reviews

Rated 4.5 out of 5 by 2 reviewers.
Rated 4 out of 5 by So far, so good Photoelectric eyes seem to be inconsistent at best. Sometimes they are hyper-sensitive and turn off at early dawn, others don't turn off even in pretty bright daylight, while others fade over time and never seem to turn off even on a summer day. So far this replacement does what one would expect, turning on at dusk and off at morning. Ask me in a year how this is working. December 4, 2014
