Customer Reviews

Great Light

Bought this for my daughter as a Christmas gift. It was for a walk-in coat closet with no light, in her new house. It works great–surprising how bright it is. Both of us plan to order more. I have a few other Mr Beams lights and really like the motion sensors. They provide light when needed. Highly recommend.

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.
