Performance & Light Output
This 1×4 air return troffer delivers high-efficacy illumination at a maximum 30W setting. It is equipped with field-selectable technology, allowing installers to toggle between 3500K, 4000K, and 5000K color temperatures directly on the unit. The frosted polycarbonate lens ensures even, volumetric light distribution that significantly reduces screen glare for improved visual comfort, backed by a robust 100,000-hour LED lifespan.
Electrical & Controls
Powered by an isolated, Class 2 constant current driver, the fixture operates smoothly on 120-277V circuits. This specific model features an integrated Passive Infrared (PIR) occupancy sensor, which detects motion via human body heat against the background environment. This requires a direct line of sight, making it exceptionally reliable and immune to false triggers in open-plan spaces. It also includes 0-10V dimming leads for secondary light level control.
Construction & Durability
The fixture is constructed from heavy-duty sheet metal, formed into an architectural center-basket profile and finished in a highly durable, high-reflectance white powder coat. The unique frame features engineered slots that allow air to pass through the fixture body into the plenum above, reducing the need for separate return grilles in the ceiling grid. It is UL listed for damp locations.
Installation & Mounting
Designed for rapid retrofitting and new construction, the luminaire fits easily into standard 1×4 T-grid suspended ceilings. It features pre-installed integral grid clips that bend firmly over the T-bar to secure the unit against seismic activity and vibration. Electrical splices are made easily via the top access plate, and support wire holes are provided for anchoring to the structural ceiling per commercial safety codes.
