Performance & Light Output

This 2x4 troffer outputs a maximum of 5,882 lumens at its highest 49W setting during normal operation, achieving exceptional efficacy for commercial environments. In the event of a power failure, the integrated battery automatically activates, supplying standby power to operate the fixture at a reduced illumination level for a minimum of 90 minutes. It features comprehensive field-selectability with three distinct color temperatures and three wattage levels. The optical design utilizes a frosted polycarbonate lens to ensure smooth, glare-free volumetric light distribution.

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 during normal use. Installers must ensure an unswitched hot supply line is connected to properly charge the emergency battery system and allow it to function during localized outages.

Construction & Durability

Engineered for lightweight durability and contractor-friendly installation, the fixture features a robust 20-gauge cold-rolled steel 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.
