The light bar has, prima facie a good quality. Have under our stairs in the hallway a panel built. Wanted to allow the pipes that cover higher than plaster and simultaneously and use the "dead space" for drinks so. This can also be found in the dark a little, but there we have no outlet, this light bar was a good alternative. Two pieces illuminate this "room" completely. The motion detector works and you open the door. The default time is sufficient for us. You can see the light bar either glue or screws. Material is. Hold How long the 4 batteries (not included) has yet to be tested. I'm going to order me this light bar again to light my steps so. Conclusion: 100% buy recommendation.
