Performance & Light Output

This 1x4 troffer delivers high-efficacy illumination at a maximum 30W setting, optimized for continuous operation in commercial spaces. 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. It includes 0-10V dimming leads for integration with daylight harvesting or building management systems. The driver features integral surge protection to defend against standard commercial electrical grid fluctuations.

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 fully enclosed design minimizes dust accumulation and protects the internal LEDs. It is strictly IC rated, authorizing safe, direct contact with standard ceiling insulation, and carries a UL listing for use in damp environments.

Installation & Mounting

Designed for rapid retrofitting and new construction, the luminaire fits easily into standard 1x4 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.
