The Advanced Vandal Resistant (AVR) luminaires are constructed of heavy gauge extruded aluminum. Cast aluminum end caps fully envelope the extruded polycarbonate linear ribbed clear diffuser. Parts are powder coated in a durable matte white finish and the lens is retained by recessed tamper-resistant set screws. The AVR series is available in lengths from 2-4 feet and can accommodate up to three T5 or T8 lamps. The lamps are also available with a fully concealed motion detector and bi-level or full on/off options.
