Points to ponder
Color: Batteries Powered, Color: Batteries Powered
Attractive shelves and good illumination, but must be turned on and off manually and individually. Not spaced to secure to studs so gigantic anchors are provided but nothing to hide or secure the AAA battery power supply required for each shelf. No ability to dim and no remote on these units at this price point but I will find a place for these shelves which are attractive and good value if you aren’t as reluctant as me to put heavy things on them or as lazy as me.

Vision came to life!!

I am pleased with my purchase, I wanted a spot light but I like the strip. The picture was taken in the early evening, it gives a great ambiance. Lights start to dim as the batteries die, easy installation.
I used tan tape to cover the power cord, the shelves are above eye level so you can’t see it.
