Performance & Light Output

This 2x2 troffer delivers high-efficacy illumination at a maximum 30W setting during normal operation. In the event of a power failure, the integrated emergency battery activates, operating the fixture at a reduced lumen output to safely illuminate evacuation paths. It is equipped with field-selectable technology, allowing installers to toggle between 3500K, 4000K, and 5000K color temperatures. The frosted polycarbonate lens ensures even, volumetric light distribution that significantly reduces screen glare.

Electrical & Controls

Powered by an isolated constant current driver, the fixture operates smoothly on 120-277V circuits. This model features an integrated Microwave (MVS) occupancy sensor, which emits high-frequency waves to detect fine motion through minor physical obstructions, ensuring lights remain on when spaces are occupied. The emergency system includes a visible indicator light and test switch to verify battery health, requiring an unswitched hot line for continuous charging.

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 2x2 T-grid suspended ceilings. It features pre-installed integral grid clips that bend firmly over the T-bar to secure the unit. 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.
