40 Watt 2X4 LED Back Lit Panel | 5558 Lumens | 4000K | 100-277V

Product Overview

This 40 watt 2x4 LED back lit panel delivers 5558 lumens at 4000K neutral white, producing 139 lumens per watt. The fixture measures 23.75 inches by 47.75 inches by 1.25 inches and weighs 9 pounds. It operates on 100-277V input at 50/60 Hz and replaces fluorescent troffers in standard 2x4 ceiling grid openings.

The housing is constructed from corrosion-resistant aluminum alloy with a white finish. An anti-yellowing polycarbonate lens provides uniform light distribution across a 140-degree beam angle with minimal glare. The fixture is rated for 50,000 hours at L70.

Where This Product Fits Best

This panel fits standard 2x4 ceiling grid systems and works in spaces currently using fluorescent troffers. The 4000K color temperature and 80+ CRI output suit general workspace environments where neutral white light and accurate color rendering are appropriate.

The 100-277V operating range allows installation across most commercial electrical systems without voltage-specific fixture selection. The 1.25-inch depth accommodates typical plenum clearances in drop ceiling applications.

Performance and Functional Considerations

At 40 watts and 5558 lumens, this fixture produces 139 lumens per watt. The polycarbonate diffuser distributes light across a 140-degree beam angle, reducing visible hotspots and minimizing direct glare.

The built-in LED driver includes low voltage protection, short circuit protection, and circuit overload protection. The driver supports 1-10V dimming for facilities with compatible dimming infrastructure.

Installation and Long-Term Use

This fixture supports three mounting methods: recessed drop-in for grid ceiling installations, surface mount, or chain and cable suspension. The aluminum alloy housing resists corrosion over the fixture''s service life.

The anti-yellowing polycarbonate lens maintains optical clarity and light transmission quality over time. At 9 pounds, the fixture handles consistently with standard 2x4 ceiling panels during installation and any future service access.

How This Fixture Is Commonly Used

Facility operators typically use this panel as a direct fluorescent troffer replacement in offices, classrooms, healthcare facilities, and retail back-of-house areas. The 4000K output provides neutral white light that works across general task and ambient applications without strong warm or cool bias.

Where 1-10V dimming systems are already in place, the fixture integrates into existing zone control schemes. The wide 140-degree beam angle fills grid bays evenly, which reduces the contrast between lit and unlit areas in open ceilings.
