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

Product Overview

This 2x4 LED backlit panel light delivers selectable wattage at 25, 30, or 40 watts with corresponding lumen outputs of 3250, 3900, or 5200 lumens. Color temperature is adjustable between 3500K, 4000K, and 5000K. The fixture operates on 100-277V input and dimensions measure 23.75 inches by 47.75 inches by 2.25 inches with a weight of 8 pounds per panel.

The backlit design uses an aluminum alloy housing with a corrosion-resistant frame and an anti-yellowing polycarbonate lens that distributes light across a 140-degree beam angle. The integrated LED driver supports 0-10V dimming and includes low voltage protection, short circuit protection, and circuit overload protection. This product is sold in packs of 4.

Where This Product Fits Best

This panel replaces fluorescent troffers in standard 2x4 ceiling grid applications. The 100-277V input range supports both commercial and light industrial electrical systems without requiring transformer matching. Operating temperature range spans -4°F to 122°F, which covers typical conditioned interior spaces.

The white fixture finish and backlit configuration suit offices, retail spaces, healthcare facilities, educational buildings, and other environments where uniform overhead illumination with minimal glare is expected. Mounting options include drop-in recessed installation for grid ceilings, surface mount, or chain and cable suspension.

Performance and Functional Considerations

Lumen output at 130 lumens per watt remains consistent across all three wattage settings. The 25-watt setting produces 3250 lumens, 30 watts produces 3900 lumens, and 40 watts produces 5200 lumens. CRI is rated at 80+, which provides adequate color rendering for general task and ambient lighting applications.

The 0-10V dimming protocol integrates with building automation systems and wall dimmers that use this control standard. Rated lifespan reaches 150,000 hours at L70, meaning the fixture will maintain 70% of initial lumen output at that point. The polycarbonate diffuser resists yellowing over time, which helps preserve light quality across the fixture''s service life.

Installation and Long-Term Use

The fixture accepts three mounting methods: recessed drop-in for lay-in grid ceilings, surface mounting to hard ceilings, and chain or cable suspension for open ceiling applications. At 8 pounds per panel, structural support requirements align with standard ceiling grid capacity for 2x4 fixtures.

Wattage and color temperature selections are made using onboard switches prior to installation or during maintenance access. Once set, adjustments require physical access to the fixture. The aluminum alloy housing resists corrosion in typical interior environments, and driver protections reduce the likelihood of electrical faults affecting fixture longevity.

How This Fixture Is Commonly Used

Facilities use the wattage selector to balance light output against energy consumption based on actual space conditions. A conference room or private office may need only 25 watts, while an open floor plan with higher ceilings or darker finishes may require 40 watts to meet target illumination levels. This adjustment happens at the fixture before power-up.

Color temperature selection allows matching to existing fixtures or tenant preferences. Warmer 3500K works in reception areas and spaces where a softer appearance is appropriate. The 4000K and 5000K options suit task-oriented environments where cooler, more activating light is preferred. Once installed, the fixture operates at the selected settings without further interaction unless dimmed through the 0-10V control circuit.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. The 5-year warranty covers defects in materials and workmanship under normal use conditions.

Built-in driver protections address low voltage conditions, short circuits, and circuit overloads. These features reduce failure risk from electrical anomalies common in commercial power systems.
