The Westwood 904 is ultra-compact LED and MR16 low-voltage halogen fixtures. Model 904 provides downlight or uplight by way of its 180° rotational fixture head. Mounts directly over a standard 4-inch J-box and require a remote 12-volt step-down transformer (not included). Various lenses, louvers, and color or dichroic filters can be combined - up to three at once - to create multiple lighting effects. Lumiere's exclusive Siphon Protection System (S.P.S.) prevents water from siphoning into the fixture through its own lead wires.
