The luminaires are compact and easy to assemble and operate as expected. The motion sensor reacts very well and the light is very bright. I use the light bar in the kitchen over the sink because I have no direct light there and for the motion is great, just when I evenings still want to quickly stop what or so, I have to not always turn on the overhead light. If the bar buy again. But how long will the LED light strip with the batteries (AAA) I can not say yet.
