Lamar Lighting's new AVR series of advanced vandal resistant luminaires are constructed of heavy gauge extruded aluminum with cast aluminum end caps, which fully envelope the .156 thick 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 2'-4' lengths, and can accommodate up to three T5 or T8 lamps.  To maximize energy savings, two lamp units are available with Lamar Lighting's Occusmart HF technology incorporating a fully concealed motion detector, capable of sensing motion even when mounted behind the diffuser.  When equipped with Occusmart HF, units can be either bi-level or full on/off, with daylight hold off option.  The AVR is the industry's first truly vandal resistant 
bi-level  sensor equipped luminaire.
