25 / 30 / 40 Watt Adjustable 2X4 LED Backlit Panel Light | 3500K / 4000K / 5000K Adjustable | 100-277V | 4 Pack

Product Overview

This is a 2x4 LED backlit panel light with selectable wattage and color temperature, designed for drop ceiling grid installations in commercial and institutional interiors. The fixture replaces traditional fluorescent troffers and is suitable for standard T-bar ceilings. Typical mounting heights are 8 to 12 feet, commonly found in offices, healthcare facilities, and educational buildings.

The panel is supplied in a pack of four and supports recessed, chain-cable, or surface mounting. It operates on 100-277V and is UL listed. The fixture is intended for environments where uniform, low-glare illumination is required for visual comfort and code compliance.

Core Performance and Output

This panel offers selectable wattage settings of 25, 30, or 40 watts, delivering 3250, 3900, or 5200 lumens respectively. Efficacy is 130 lumens per watt. The fixture provides a wide 140° beam angle for even light distribution across workspaces and corridors. Color temperature can be set to 3500K, 4000K, or 5000K to match application needs.

0-10V dimming is standard for integration with compatible controls. Output is suitable for standard ceiling heights; excessive brightness may occur if installed in small rooms or at low mounting heights. Uniformity may decrease if spacing exceeds typical grid patterns.

Adjustability and Control Options

Both wattage and color temperature are field adjustable via onboard switches, allowing adaptation to changing requirements or retrofit conditions. The fixture supports 0-10V dimming for integration with building lighting controls or occupancy sensors.

No onboard motion or daylight sensors are included. Adjustment switches are accessible during installation, not intended for frequent field changes after commissioning.

Longevity and Reliability

The panel is rated for 150,000 hours (L70) at typical operating temperatures. The aluminum alloy housing and backlit design support consistent thermal management and long-term lumen maintenance.

Operating temperature range is -4°F to 122°F. The fixture is designed for continuous operation in conditioned interior spaces. No fan or active cooling is required.

Build Quality and Physical Characteristics

The fixture measures 23.75 x 47.75 x 2.25 inches and weighs 8 lbs. The housing is constructed from aluminum alloy with a white finish. The low-profile design is compatible with standard 2x4 grid ceilings and surface mount kits.

All wiring and adjustment points are accessible from the rear. The lens provides uniform diffusion and minimizes glare. The fixture is not rated for wet locations or exterior use.

Where This Product Fits Best

This panel is designed for interior environments requiring uniform, low-glare lighting and compatibility with drop ceiling grids. It is most often installed in:

• office lighting
• commercial interior lighting
• healthcare facility lighting
• educational facility lighting
• conference room lighting
• retail interior lighting
• corridor lighting
• reception area lighting

Best suited for conditioned spaces with standard ceiling heights. Not intended for wet, corrosive, or exterior environments.

Installation and Long-Term Use

The fixture is compatible with recessed grid mounting, surface mount kits, or chain-cable suspension. Installation is straightforward for standard T-bar ceilings. All wiring is accessible from the rear, and the fixture supports 100-277V input.

Routine cleaning of the lens and periodic inspection of wiring connections are recommended. Adjustment of wattage or color temperature should be performed with power off. No special maintenance is required beyond standard lighting practice.

How This Fixture Is Commonly Used

Panels are typically installed in 2x4 grid patterns at 8 to 12 foot mounting heights. Spacing follows ceiling grid layout, usually 4 to 8 feet on center depending on light level requirements. Fixtures are often grouped for uniform coverage in open offices, classrooms, or patient care areas.

Higher wattage settings reduce fixture count but may increase perceived brightness. Spacing and output should be coordinated with room size and visual comfort requirements.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. It operates on 100-277V and supports 0-10V dimming. The product is covered by a 5-year warranty. No hazardous location or wet location ratings apply.

All components are rated for use in commercial and institutional interiors. Installation must comply with local electrical codes and building standards.
