Built perfectly to fit the small remote that comes with this (and other popular LED lighting) product. The remote in question is approx. 50x83x5mm in dimension.

Designed ready to be mounted with 3 small screws which can be recessed into the holder for a slim profile. Also features a slot to easily slide the remote in and out with a single finger.

Shown mounted under a desk here, but you could also mount it on a wall or other vertical surface.
