Product Overview
This is an adjustable wattage 2x4 LED troffer designed for recessed installation in standard grid ceilings. The fixture supports selectable wattages of 20, 28, 34, or 41 watts and delivers up to 6442 lumens. Color temperature can be set to 3000K, 3500K, 4000K, 5000K, or 6500K. Typical use is in office, educational, and commercial interior environments where uniform, low-glare lighting is required.
This troffer is a direct replacement for legacy fluorescent troffers. It is suitable for mounting heights from 8 to 12 feet, commonly found in offices, classrooms, and healthcare facilities. The fixture is UL certified and operates on 100-277V input.
Core Performance and Output
The fixture provides four selectable output levels, ranging from 3390 to 6442 lumens, with an efficacy of 155 lumens per watt. The 120° beam angle and polycarbonate lens deliver wide, even distribution suitable for open-plan spaces and grid ceiling layouts. Color rendering index is 80+.
0-10V dimming is standard. Output is consistent across the full voltage range. At lower mounting heights, the highest wattage setting may produce excessive brightness. For larger rooms or higher ceilings, higher output settings improve uniformity but may require careful layout to avoid glare.
Adjustability and Control Options
Both wattage and color temperature are field adjustable using onboard switches. This allows tuning of light levels and color to match occupant needs or space requirements. The fixture supports 0-10V dimming for integration with standard dimming controls.
Adjustments can be made before or after installation. No additional accessories are required for basic adjustability. Controls are accessible from the fixture housing after removal from the ceiling grid.
Longevity and Reliability
Rated lifespan is 70,000 hours (L70). The fixture uses an aluminum alloy housing for thermal management and durability. Operating temperature range is -4°F to 122°F, suitable for conditioned interior spaces.
LEDs and driver are integrated and designed for long-term operation with minimal maintenance. The fixture is covered by a 5-year warranty. No routine re-lamping is required.
Build Quality and Physical Characteristics
The housing is constructed from aluminum alloy with a white finish. The lens is polycarbonate for impact resistance and uniform light diffusion. Fixture dimensions are 23.75 inches by 47.75 inches, with a weight of 11.4 lbs.
Recessed mounting is standard for T-bar grid ceilings. The fixture is designed for flush installation with minimal profile below the ceiling plane. All components are accessible for service from below the ceiling.
