Looking to make your energy-friendly lighting system even more efficient? Lightolier’s IntelliSight Occupancy Sensors provide tons of coverage—4,000 square feet with wall-mounted models and 2,500 with ceiling-mounted—with features such as intelligent self-adjustment mode, automatic time-out, adjustable time-out and light-level adjustments. An ambient light override shuts off your lights if there’s enough already entering the room.
