Built for durability and ease of installation, the housing is constructed from die cast aluminum with a UV stabilized powder coated finish. The fixture comes pre-wired with a control connect port built in, no additional wiring required. Light is distributed through an acrylic resin prismatic lens designed to maximize output and eliminate glare.
The ORHBS36-48L is rated for operating temperatures from -40°C to +50°C (-40°F to +122°F) and delivers long-life performance with 50,000 hours of operation at a minimum of 70% initial output (L70).

All Atlas LED luminaires are tested by an independent laboratory in accordance with IESNA LM-79 and LM-80 standards.
The integrated sensor offers three levels of control - time (3–60 minutes), sensitivity, and dimming (0–75%) - with no remote required. Settings are retained even if power is interrupted. Field installable accessories sold separately include an emergency backup kit (ORHBEM16), Control Connect sensor (IRH-MOT), and AirLink Blue quick control Bluetooth sensor (QCALBMSD35).
