Customer Reviews

Nice for Small Areas

I use this to light up a small section near my a/c units. We don't walk on that side of the house, but it's very dark and no lights in the area.

Best for Small Area

We use this light under our deck, since it's very dark. It provides very limited light; enough to see the walkway.

Good built but defective for 2nd time

I did not have the chance to test long term use.
I bought one unit and replaced and this one is defctive too. Problem is that it goes off (in dark when it senses motion) but never shuts off, lights on again and again regardless of any motion.
It is very well built structurally so i belive the brand is good, something wrong with electronics or manufacturing.
i will replce for the 3rd and the last time and see what happens.
