Rated 4.0 out of 5.0 by It saved the day. Just what I needed Home Depot came through again I had to retrofit it what was there but it worked out perfect yes I would recommend this product . I am always surprised when I find what I need in a product that I wouldn't think would be there they always have what I need . Keep up the good work . July 14, 2015
Rated 4.0 out of 5.0 by Good poduct, easy to install. The new one was easy to install, the old one was not easy to get off. I took me a long time finding out what breaker it was on. If a person had basic electrical skills they could install this with little effort. May 19, 2015
Rated 1.0 out of 5.0 by Defective out of the Box I installed one of these in a light fixture in my carport. I have a lot of experience with electrical circuits and double checked that it was wired properly. The light stays on all the time. The cheap metal shade that was included, is moved far from the sensor. There is nothing to meter, since the light is on all the time. I am left with no option but to replace this with a different brand sensor. If you google the model number, this same sensor shows up under a different brand name on Amazon, where it also gets bad reviews. July 18, 2013
Rated 1.0 out of 5.0 by Failed in 5 minutes Installed this on a 2 amp draw (240Watt) circuit and it stopped working in 5 min. It would not turn on the lights even if tape was over the sensor. I am an electrician by trade. April 6, 2015
Rated 1.0 out of 5.0 by Don't buy, unless you like to buy often For 17 years I have been fixing the lights at our neighborhood entrance and I have had this switch fail after 1 year. It has happened 2 years in a row. So I am shopping for a better one March 8, 2015
Rated 5.0 out of 5.0 by Good product for the price I put this light sensor inline between a power supply and a double box with two receptacles to use for our Christmas lights instead of buying timers for the different areas to be lit. Everything is outside. Works like a charm............... December 10, 2013
Rated 5.0 out of 5.0 by Works as described I have purchased several of this item throughout the years and they are still working. They are sealed where the wires come through the outlet and this is a plus. May 20, 2014
Rated 5.0 out of 5.0 by This photocell is perfect for location in shadowy sophets!!! Worked great- used to run exterior lights dusk to dawn! Had installed the unit that comes in weatherproof blank (the installation was in a sophet), it would not turn off the lights because of too much shadow in the sophet. This photocell gave me the ability to install in the sophet but point away from the shadow created in the sophet. My customer is quite pleased with finished product! January 14, 2014
