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 indoor fixture for recessed ceiling installations. It provides selectable wattage and color temperature settings for office lighting, commercial interior lighting, healthcare facility lighting, and educational facility lighting.
The panel produces a broad 110-degree distribution through a polycarbonate lens. It replaces fluorescent troffers in compatible recessed ceiling layouts and can also be surface mounted or suspended with optional chain-cable mounting.
Core Performance and Output
Selectable wattage settings are 30W, 40W, and 50W. Corresponding output levels are 3750, 5000, and 6250 lumens, with an efficacy of 125 lumens per watt.
Selectable color temperatures are 3500K, 4000K, and 5000K. The fixture has an 80+ CRI, 0-10V dimming, 100-277V input, and 50/60Hz operation.
The 110-degree beam angle supports broad general illumination across a ceiling plane. The 6250-lumen setting can be excessive in lower-ceiling layouts where lower output settings provide the required light level.
Adjustability and Control Options
Wattage adjustment provides 30W, 40W, and 50W operating selections. Color temperature adjustment provides 3500K, 4000K, and 5000K selections.
0-10V dimming is included. Input voltage is 100-277V.
Longevity and Reliability
The rated lifespan is 50,000 hours at L70. The fixture operates from -4F to 122F.
Long-term performance depends on maintaining suitable electrical connections, mounting support, and operating conditions within the stated temperature range. The five-year warranty applies to the fixture.
Build Quality and Physical Characteristics
The housing is aluminum alloy with a white finish. A polycarbonate lens covers the LED assembly and distributes light across the panel face.
The fixture measures 47.81 inches long, 23.78 inches wide, and 1.3 inches high. Fixture weight is 7 pounds.
Standard mounting is recessed. Optional surface and chain-cable mounting configurations are available.
Where This Product Fits Best
This panel light fits interior ceiling applications that use 2×4 recessed fixtures or require a surface-mounted or suspended panel configuration. Its adjustable output and color settings support spaces with changing light-level or color-temperature requirements.
- office lighting
- commercial interior lighting
- healthcare facility lighting
- educational facility lighting
- conference room lighting
- corridor lighting
- reception area lighting
The aluminum alloy housing, polycarbonate lens, and stated operating range support indoor installations within the published temperature limits. Recessed mounting requires a compatible ceiling opening and support arrangement.
Installation and Long-Term Use
Recessed mounting is the standard installation method. Surface mounting and chain-cable mounting are optional configurations where the ceiling construction supports those methods.
Installers should set wattage and color temperature before final commissioning. Verify 100-277V supply voltage and 0-10V control wiring where dimming is required.
For long-term service, keep the lens clean and inspect mounting and electrical connections during normal lighting maintenance. The 1.3-inch fixture depth should be confirmed against available ceiling space for recessed installations.
How This Fixture Is Commonly Used
In office lighting and commercial interior lighting, panels are arranged in ceiling grids to create consistent general illumination. In healthcare facility lighting and educational facility lighting, color temperature and output settings are selected to match the planned interior lighting condition.
Mounting height is determined by the ceiling system and project light-level requirements. Corridor lighting and reception area lighting commonly use repeated panel layouts that follow the ceiling grid or room geometry.
Fixture spacing varies with the selected wattage, mounting height, target light levels, and layout requirements. Higher output settings can reduce fixture count, while lower settings allow closer control of light levels.
Safety, Certifications, and Warranty
This panel light is ETL certified and rebate eligible.
The fixture has a five-year warranty. Use within the stated 100-277V voltage range and -4F to 122F operating temperature range.
