20 / 25 / 30 Watt Adjustable 1X4 LED Backlit Panel Light | 2760 to 3900 Lumens | 3500K / 4000K / 5000K | 100-277V

Product Overview

This 1X4 LED Backlit Panel is a wattage and color adjustable fixture designed for drop ceiling, surface, or suspended mounting in commercial and institutional interiors. It delivers selectable output from 2760 to 3900 lumens and operates on 100-277V. Typical use includes office, healthcare, and educational environments where uniform, low-glare illumination is required. The panel is a direct replacement for 32W fluorescent troffers and is suited for mounting heights up to 12 feet.

The fixture features a slim, low-profile form factor and a polycarbonate lens for even light distribution. It is UL listed and IP40 rated for use in controlled indoor spaces. The panel is commonly installed in grid ceilings, but can also be surface or cable/chain mounted where grid is not present.

Core Performance and Output

This panel offers three selectable wattages?20W, 25W, and 30W?providing 2760, 3250, or 3900 lumens respectively. Efficacy is 130 lumens per watt. The 110° beam angle delivers wide, uniform coverage suitable for open plan areas and corridors. Color temperature can be set to 3500K, 4000K, or 5000K as needed for the application.

0-10V dimming is standard for integration with common lighting controls. Output is appropriate for typical ceiling heights found in offices, classrooms, and healthcare spaces. Excessive output may cause glare in rooms with low ceilings or highly reflective surfaces. Uniformity may decrease if spacing exceeds standard troffer layouts.

Adjustability and Control Options

Both wattage and color temperature are field adjustable via onboard switches. This allows tuning of light levels and color to match occupant needs or space requirements without replacing the fixture. 0-10V dimming enables integration with building lighting control systems for energy management or occupancy-based operation.

No onboard occupancy or daylight sensors are included. Controls are compatible with standard 0-10V dimming infrastructure. Adjustments should be made prior to ceiling installation for ease of access.

Longevity and Reliability

The fixture is rated for 70,000 hours of L70 life at ambient temperatures from -4°F to 122°F. The LED array and driver are thermally managed within an aluminum alloy housing to maintain performance over time. Polycarbonate lens resists yellowing and impact in typical commercial environments.

Routine cleaning of the lens and housing is recommended to maintain light output. No relamping is required. The fixture is covered by a 5-year warranty.

Build Quality and Physical Characteristics

The panel uses an aluminum alloy housing for rigidity and heat dissipation. The polycarbonate lens provides even diffusion and is secured to prevent dust ingress. The fixture measures 11 7/8 in x 47 3/4 in x 1 3/4 in and weighs 12 lbs. Finish is white for ceiling integration.

IP40 rating protects against solid objects larger than 1mm but does not provide water resistance. The fixture is suitable for dry, controlled environments only. Mounting options include recessed (T-bar grid), surface, or chain/cable suspension.

Where This Product Fits Best

This panel is designed for controlled indoor environments requiring uniform, low-glare illumination. It is most often used in spaces with drop ceilings or where surface mounting is required. The fixture is appropriate for new construction or retrofit projects replacing fluorescent troffers.

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

Environments should be dry and free from airborne contaminants or moisture. Not intended for wet locations or areas requiring sealed or vapor-tight fixtures.

Installation and Long-Term Use

The fixture is compatible with standard 1X4 grid ceilings for recessed installation. Surface and chain/cable mounting kits are available for hard ceilings or open plenum spaces. The low profile allows installation in shallow ceiling cavities.

Wiring is accessible from the rear and supports 100-277V input. All adjustments for wattage and color temperature should be made prior to final mounting. Routine inspection and cleaning will maintain appearance and output. No lamp or ballast maintenance is required.

How This Fixture Is Commonly Used

Panels are typically installed in grid ceilings at heights from 8 to 12 feet. Spacing matches standard troffer layouts, usually 4 to 8 feet on center depending on desired light levels and room geometry. In corridors, fixtures are aligned for continuous illumination.

Higher output settings reduce fixture count but may increase perceived brightness or glare in smaller rooms. Color temperature is often selected to match adjacent spaces or occupant preference.

Safety, Certifications, and Warranty

This fixture is UL listed and IP40 rated. It meets requirements for use in commercial and institutional interiors. The product is eligible for utility rebates where applicable. Warranty coverage is 5 years from date of installation.

No special safety procedures are required beyond standard electrical installation practices. Not suitable for wet or hazardous locations.
