OPEN FACE - This 12V in-ground light features a thick, solid cast brass top with an open face for maximum light output. The socket is mounted on a gimbal so the lamp angle can be adjusted. WATERTIGHT - The commercial grade glass lens is flush with the top to prevent water from puddling. A thick rubber gasket between the cap and in-ground canister creates a watertight seal, and a pressure fitting prevents water intrusion at the 4-foot lead wire exit, so water can't enter from the bottom. OPTIMAL ILLUMINATION - With the included 5W LED MR16 bulb, this fixture produces 340 lumens of warm white (2700K) light. LOW VOLTAGE - Powered by safe 12V AC current. As with all 12V fixtures, a low voltage transformer (not included) is required for operation LIFETIME WARRANTY - This fixture is UL/cUL listed and backed by the Lumen Logic lifetime warranty.
