Customer Reviews

Easy to install and easy to use

This is a nice product that is easy to install and easy to use. Very reasonably priced.


I have one in a storage shed. It works so well that I had to order 4 more for other locations and family.

Excellent product for early birds

This product was a great call by my wife. We installed it inside our closet, in the master bedroom. It lights up the entire closet and the area just in front of the closet–enough to get dressed early in the morning–while leaving the rest of the bedroom dark enough not to disturb those sleeping. I'm seriously thinking about buying more for around the home.
