Performance & Light Output

This 2x4 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 expansive 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. It includes standard 0-10V dimming leads, capable of dimming down to 10 percent, which facilitates smooth integration with daylight harvesting sensors and energy management systems. The driver features integral surge protection to defend against standard commercial electrical grid fluctuations.

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 2x4 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.
