Designed to open up the room and distribute light along both the vertical and horizontal workspace, Keystone’s LED strip fixtures offer uniform and comfortable lighting. Ideal in hospital, school, and retail applications where lighting is important, XFit Micro Strips are a high efficacy solution for new construction or fluorescent strip fixture replacement applications.
The compact form factor of Keystone’s XFit Micro Strip light fixtures makes them extremely flexible to fit in restrictive areas. For such a small strip light fixture, the XFit Micro Strip is powerful, providing up to 7,210 lumens at 134 lm/W.
And Micro Strips are available with Keystone’s Power Select and Color Select technologies, which allow users to choose from among a variety of power outputs and color temperatures by flicking a switch.
Our LED strip fixtures provide suitable lighting without the maintenance issues associated with fluorescent strip fixtures. Installation is quick and simple when mounting on the surface of the ceiling.
