Performance & Light Output

This 1x4 frame light outputs a maximum of 4,994 lumens at its highest 40W setting, achieving an excellent efficacy of up to 131 lumens per watt. It features comprehensive field-selectability with five distinct color temperatures (ranging from a warm 3000K to a crisp 6500K) and five wattage levels, allowing precise visual tuning for any environment. 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 to ensure safe building evacuation.

Electrical & Controls

Powered by a high-efficiency driver operating on a universal 120-277V circuit, this luminaire ensures stable performance across standard commercial grids. It includes standard 0-10V dimming leads to facilitate smooth integration with daylight harvesting sensors and energy management systems. The emergency system includes a visible charging indicator light and a test button to ensure the battery remains functional and compliant with routine safety inspections.

Construction & Durability

Engineered for lightweight durability, the fixture consists of a robust aluminum frame finished in clean white to blend seamlessly with standard ceiling grids. The ultra-slim 1-inch profile makes it exceptionally easy to handle and ideal for installations constrained by shallow ceiling plenums. The unit is strictly IC rated, meaning it is certified safe for direct contact with building thermal insulation, and carries a UL damp location listing for use in environmentally controlled interior spaces.

Installation & Mounting

The frame is designed for rapid, drop-in installation into standard 1x4 recessed T-bar ceiling grids. The slim frame rests directly on the grid structure, while the remote driver and off-board emergency battery pack clip securely onto the adjacent T-bar bracket. Installers must ensure an unswitched hot supply line is connected to charge the battery system, and a provided tether cable must be anchored to the grid support wire for compliance with commercial safety codes.
