Rated 2.0 out of 5 by 20 reviewers.
Rated 1.0 out of 5.0 by Burns out your lights I purchased about 4 of them within a week my front porch lights blow out. I had to purchase some more led light bulbs for the front. The dusk to dawn screw-in light control had the bulbs flicking throughout out the whole day/week. Which in turn case the light bulbs to blow out. Do Not Buy waste of money I took them back and got my money back. September 15, 2011
Rated 5.0 out of 5.0 by good product It does what it says...if you follow the directions. After install, waited till sundown and the lights began to flicker, I cursed the product and began packing them up to return when I (accidentaly) read the directions. I added the posts that came with the package and they have worked flawlessly ever since. Great value for the price. October 16, 2012
Rated 1.0 out of 5.0 by They stay on. They stay on in daylight slightly overcast day. needs bright sun to shut off. no good... February 20, 2015
Rated 1.0 out of 5.0 by not effective in outdoor use too short, so sensor is buried too deep in the outdoor fixture so it does not get sunlight ... and therefore does not turn off during the daylight hours May 19, 2014
Rated 1.0 out of 5.0 by Lousy I am a contractor and have attempted to use this product in several locations without success. The current one I have replaced 3 times and in each case the light is still on during the day !!!!! January 17, 2013
Rated 1.0 out of 5.0 by Hate it, getting ready to return it. It supposed to make your light work from dusk til dawn and it stays on 24 hrs a day. August 12, 2014
Rated 1.0 out of 5.0 by Light controler This doesn't work. Even direct sunlight doesn't trigger the light to turn off. August 6, 2014
Rated 1.0 out of 5.0 by Rubbish Have no idea what is the problem, but these items no longer go on and off. Only on. Returned another today. Don't bother with any of these. I hope to one day to change the fixture instead. November 21, 2013
