When you need maximum adjustability on your surface mounted light combined with a smaller form factor, the Sentry-short-MT is your light. The multi-axis - pivoting knuckle allows for 540° about the horizontal and vertical axis. A single tightening bolt (thumb screw) secures movement of the light fixture in both planes. The Medallion Trim surface mount delivers a clean, modern style. You still get the LED performance of the MR16 lamp.
