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. The edge-lit LED design utilizes a frosted polycarbonate lens to ensure smooth, glare-free light distribution while maintaining an 80+ CRI over an extended 100,000-hour operational lifespan.

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, capable of dimming down to 10%, which facilitates smooth integration with daylight harvesting sensors and energy management systems. The driver features integrated surge protection and a high power factor to protect internal components from electrical grid fluctuations.

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. It does not require a separate bulky housing; the slim frame rests directly on the grid structure, while the remote driver assembly clips securely onto the adjacent T-bar. A provided tether cable allows the installer to securely anchor the unit to the grid support wire or structural ceiling to comply with commercial safety codes.
