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

Product Overview

This 40 Watt 2X4 LED Back Lit Panel is designed for drop ceiling grid installations in commercial interiors. It delivers uniform, low-glare illumination suitable for spaces where visual comfort and consistent light levels are required. Typical use cases include office spaces, healthcare facilities, and educational environments where fluorescent troffers are being replaced with LED panels.

The fixture operates at 100-277V and produces a neutral white 4000K color temperature. It is compatible with standard recessed mounting and can be adapted for chain-cable or surface mounting where grid ceilings are not present.

Core Performance and Output

This panel outputs 5558 lumens at 40 watts, providing an efficacy of 139 lumens per watt. The 140° beam angle ensures wide, even coverage across open-plan areas and corridors. The fixture supports 1-10V dimming for integration with common lighting controls.

At standard ceiling heights (8?12 ft), output is balanced for general ambient lighting without excessive glare. At lower mounting heights, output may be higher than needed for some tasks. Uniformity may decrease if panels are spaced beyond typical grid patterns.

Adjustability and Control Options

The fixture supports 1-10V dimming, allowing for integration with compatible dimming systems and occupancy sensors. This enables energy savings and adaptable light levels based on occupancy or daylight conditions.

No onboard adjustability for color temperature or beam angle is provided. Dimming performance is stable across the full voltage range.

Longevity and Reliability

The panel is rated for 50,000 hours (L70), supporting long-term operation in commercial settings with minimal maintenance. The LED driver and back-lit design reduce thermal stress, contributing to consistent performance over time.

Aluminum alloy housing and polycarbonate lens provide durability for daily use in high-traffic environments. The fixture is suitable for continuous operation in temperature-controlled interiors.

Build Quality and Physical Characteristics

The housing is constructed from aluminum alloy for rigidity and heat dissipation. The polycarbonate lens delivers uniform light diffusion and resists yellowing. The fixture is finished in white to blend with standard ceiling grids.

Dimensions are 23.75 in x 47.75 in x 1.25 in, with a weight of 9 lbs. The low-profile design allows for installation in shallow plenum spaces. All components are UL certified.

Where This Product Fits Best

This panel is intended for indoor commercial environments where uniform, low-glare lighting is required. It is most often installed in drop ceiling grids but can be adapted for surface or suspended mounting as needed.

• 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 temperature-controlled interiors with standard ceiling heights. Not intended for wet locations or environments with high dust or corrosive exposure.

Installation and Long-Term Use

The fixture is designed for recessed mounting in standard 2x4 grid ceilings. Optional chain-cable or surface mounting kits are available for non-grid installations. Installation requires access to the plenum for wiring and fixture placement.

Routine cleaning of the lens and periodic inspection of electrical connections are recommended for optimal performance. The fixture is compatible with most commercial dimming and control systems.

How This Fixture Is Commonly Used

Panels are typically installed in continuous rows or grid patterns to provide uniform ambient lighting. Standard mounting heights range from 8 to 12 feet, matching typical commercial ceiling heights. Spacing is determined by grid layout and target light levels.

Reducing fixture count by increasing spacing may lead to lower uniformity. Higher output per panel can reduce the number of fixtures needed but may increase perceived brightness in smaller rooms.

Safety, Certifications, and Warranty

This fixture is UL certified and meets requirements for commercial interior lighting. It is eligible for utility rebates where available. The product includes a 5-year warranty covering manufacturing defects and performance.

All components are rated for safe operation within the specified voltage and frequency range. No special maintenance procedures are required beyond standard electrical safety practices.
