25 / 30 / 40 Watt Adjustable 2X4 LED Backlit Panel Light | 3500K / 4000K / 5000K Adjustable | 100-277V | Emergency Battery Backup | 2 Pack

Product Overview

This is a 2x4 LED backlit panel light with selectable wattage (25W, 30W, 40W) and color temperature (3500K, 4000K, 5000K). It is designed for drop ceiling grid installation in commercial interiors, offices, healthcare facilities, and educational buildings. The fixture includes an integrated emergency battery backup and supports multiple mounting options: recessed, chain-cable, or surface mount.

Typical use is as a direct replacement for fluorescent troffers in T-bar ceilings, providing uniform, low-glare illumination. The panel is suitable for mounting heights up to 12 feet, commonly found in office suites, classrooms, and patient care areas.

Core Performance and Output

This panel delivers 3250 to 5200 lumens, depending on the selected wattage. Efficacy is 130 lumens per watt. The 140° beam angle provides wide, even coverage with minimal shadowing. Color temperature can be set to 3500K, 4000K, or 5000K to match existing lighting or user preference.

0-10V dimming is standard. Output is appropriate for general ambient lighting in commercial interiors. At mounting heights above 12 feet, light levels may decrease and uniformity may be reduced. Excessive output may occur if used in small rooms at the highest wattage setting.

Adjustability and Control Options

Both wattage and color temperature are field-selectable via onboard switches. This allows tuning of light levels and color to suit the space or application. The fixture supports 0-10V dimming for integration with standard commercial lighting controls.

An emergency battery backup is included, providing code-required egress illumination during power loss. No advanced networked controls are integrated; external controls can be used if compatible with 0-10V dimming.

Longevity and Reliability

L70 rated life is 150,000 hours. The fixture uses an aluminum alloy housing and polycarbonate lens for durability in typical commercial environments. Operating temperature range is -4°F to 122°F, suitable for conditioned spaces.

Emergency battery backup is integrated and does not require separate installation. No routine maintenance is required beyond periodic cleaning and battery function checks as part of standard facility procedures.

Build Quality and Physical Characteristics

The panel measures 23.75 x 47.75 x 2.25 inches and weighs 8.8 lbs. The housing is aluminum alloy with a white finish. The lens is polycarbonate for impact resistance and uniform light diffusion.

Mounting options include recessed (standard), chain-cable, or surface mount. The fixture is designed for compatibility with standard 2x4 grid ceilings. All components are UL listed.

Emergency battery backup is pre-installed. Wiring supports 100-277V input. Routine cleaning of the lens and periodic battery checks are recommended for long-term performance. No relamping is required.

How This Fixture Is Commonly Used

Panels are typically installed in grid ceilings at heights of 8 to 12 feet. Spacing is usually 8 to 12 feet on center, depending on target light levels and room geometry. Uniform layout is common in open offices, classrooms, and corridors.

Wattage and color temperature are set during installation or commissioning. Higher output settings can reduce fixture count but may increase perceived brightness or glare in smaller rooms.
