Performance & Light Output
This 2×4 troffer outputs a maximum of 4,884 lumens at its highest 40W setting, achieving an excellent efficacy of up to 143 lumens per watt. It features comprehensive field-selectability with three distinct color temperatures (3500K, 4000K, and 5000K) and three wattage levels, allowing precise visual tuning for any environment. The optical design utilizes a frosted polycarbonate lens to ensure smooth, glare-free volumetric light distribution while maintaining an 80+ CRI over its extended 100,000-hour operational lifespan.
Electrical & Controls
Powered by a high-efficiency Class 2 driver operating on a universal 120-277V circuit, this luminaire ensures stable performance across standard commercial grids. This specific model features an integrated Microwave (MVS) occupancy sensor, which detects fine motion through minor physical obstructions, ensuring lights remain on when spaces are actively occupied. It also includes standard 0-10V dimming leads, capable of dimming down to 10 percent.
Construction & Durability
Engineered for lightweight durability and contractor-friendly installation, the fixture features a robust housing finished in a clean white coating to blend seamlessly with standard ceiling grids. 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 environmentally controlled damp interior spaces.
Installation & Mounting
The fixture is designed for rapid, drop-in installation into standard 2×4 recessed T-bar ceiling grids. It rests securely on the grid structure, allowing for quick deployment in both retrofit and new construction projects. It features integral grid clips that bend over the T-bar to secure the unit against vibration, and support wire holes are provided for anchoring to the structural ceiling per commercial safety codes.
