Performance & Light Output
This 1×4 troffer outputs a maximum of 5,142 lumens at its highest 40W setting, achieving an excellent efficacy of up to 147 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 polystyrene lens to ensure smooth, glare-free light distribution while maintaining an 80+ CRI over its extended 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. For enhanced functionality, this unit is compatible with optional third-party 0-10V dimming controls (sold separately).
Construction & Durability
Engineered for lightweight durability, the fixture consists of a robust aluminum frame and a cold-rolled steel back housing, finished in a clean white powder coat to blend seamlessly with standard ceiling grids. The enclosed unit carries an IP20 ingress protection rating against dust, and it is strictly UL listed for use in environmentally controlled damp interior spaces. It reliably starts in extreme temperatures down to -4 degrees Fahrenheit and operates safely in ambients up to 113 degrees Fahrenheit.
Installation & Mounting
The fixture is designed for rapid, drop-in installation into standard 1×4 recessed T-bar ceiling grids. It rests securely on the grid structure, allowing for quick deployment in both retrofit and new construction projects. Installers can adapt the unit for alternative applications using optional surface and recessed mounting kits designed specifically for drywall ceilings (sold separately), ensuring versatile placement across varied architectural layouts.
