25 / 30 / 40 Watt Adjustable 2X4 LED Backlit Panel Light | 3500K / 4000K / 5000K Adjustable | 100-277V | 4 Pack
This 2X4 LED backlit panel is a strong choice for commercial and institutional spaces with grid ceilings due to its selectable wattage (25/30/40W) and color temperature (3500K/4000K/5000K), allowing tailored light levels and appearance for offices, classrooms, retail, and healthcare environments. Its corrosion-resistant aluminum frame and anti-yellowing polycarbonate lens ensure long-term durability and consistent light quality, while the 0-10V dimming supports energy management. The fixture’s broad 140° beam angle delivers even coverage, and multiple mounting options accommodate varied ceiling types. It is not suitable for wet locations or hazardous environments.

Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout. When IES photometry is available, workplane height and room reflectance controls are shown.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This field is used only when usable IES photometry is not available. In fallback mode, it acts as a simplified room utilization factor for reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45. When IES photometry is active, this field is hidden and the estimator uses the selected workplane height, LLF, and simplified reflectance adjustment instead.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data, selected workplane height, light loss factor, and simplified reflectance adjustment to estimate fixture count, average foot-candles, and visual light distribution. The reflectance adjustment is a conservative approximation and is not a full zonal-cavity, radiosity, or professional photometric room calculation. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces and should be used as a planning aid, not a final photometric lighting plan. Actual light levels may vary based on fixture optics, selected IES file, mounting conditions, workplane height, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements. Project-critical applications should be verified with a formal lighting plan.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
Product Overview
This 2×4 LED backlit panel light is an adjustable-output troffer fixture for recessed commercial ceilings. It provides selectable wattage and color temperature settings in one fixture body.
The fixture is designed to replace fluorescent troffers in office lighting, healthcare facility lighting, educational facility lighting, and other commercial interior lighting layouts. It is sold in packs of 4.
Core Performance and Output
Selectable wattage settings of 25W, 30W, and 40W produce 3250, 3900, and 5200 lumens. Fixture efficacy is 130 lumens per watt.
The 140 degree distribution provides broad downward light for typical 2×4 troffer layouts. The 40W setting can create more light than needed in low-light commercial interior lighting areas, while the lower settings allow output to be reduced where fixture spacing is closer.
The fixture operates on 100-277V, 50/60Hz electrical systems. It has an 80+ CRI rating.
Adjustability and Control Options
Field-selectable wattage allows the fixture to operate at 25W, 30W, or 40W. Field-selectable color temperature settings include 3500K, 4000K, and 5000K.
0-10V dimming is supported. Dimming controls must be compatible with the fixture’s 0-10V dimming input.
Longevity and Reliability
The rated L70 life is 150,000 hours. This rating identifies the point at which light output is expected to reach 70 percent of initial output.
The fixture is rated for operation from -4 degrees F to 122 degrees F. Long-term performance depends on maintaining suitable electrical connections and operating conditions.
Build Quality and Physical Characteristics
The fixture uses an aluminum alloy housing with a white finish. Overall dimensions are 23.75 x 47.75 x 2.25 inches.
Fixture weight is 8 pounds. The standard mounting method is recessed installation, with chain-cable and surface mounting options available.
Where This Product Fits Best
This panel light fits commercial interior ceiling layouts that use 2×4 troffer fixtures and require adjustable output or selectable color temperature. Its broad distribution suits general lighting layouts rather than narrow-beam lighting tasks.
- office lighting
- healthcare facility lighting
- educational facility lighting
- commercial interior lighting
- conference room lighting
- corridor lighting
The recessed configuration supports standard troffer-style ceiling installations. Chain-cable and surface mounting options address locations where recessed mounting is not used.
Installation and Long-Term Use
Recessed mounting is the standard installation method. Confirm ceiling opening dimensions, support conditions, branch voltage, and dimming wiring before installation.
Chain-cable and surface mounting require the applicable mounting arrangement. Select wattage and color temperature before final commissioning so fixtures within the same layout operate consistently.
How This Fixture Is Commonly Used
In office lighting and educational facility lighting layouts, these fixtures are generally arranged in rows aligned with the ceiling grid. In healthcare facility lighting and corridor lighting layouts, fixture placement follows the existing ceiling pattern and required light distribution.
Mounting height affects the light level reaching the work plane and the uniformity between fixtures. Higher output can reduce the number of active lumens needed from each location, but final spacing depends on mounting height, selected wattage, and layout requirements.
Safety, Certifications, and Warranty
This fixture is UL listed and rebate eligible.
The fixture includes a 5-year warranty. It operates on 100-277V and is rated for -4 degrees F to 122 degrees F.
