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 a wattage-selectable and color-selectable troffer for recessed ceiling installations. It operates from 100-277V and includes an emergency battery backup.
The fixture is configured for office lighting and healthcare facility lighting where a fluorescent troffer replacement is needed. Recessed mounting is standard, with chain-cable and surface mounting options available.
Core Performance and Output
The selectable wattage settings are 25W, 30W, and 40W. Output is 3250, 3900, or 5200 lumens, with an efficacy of 130 lumens per watt.
The 140-degree distribution and polycarbonate lens provide broad illumination from a 2×4 ceiling panel format. Lower output settings help control light levels in smaller rooms, while the 40W setting can produce excessive output where lower light levels are required.
The fixture operates on 100-277V, 50/60Hz power and supports 0-10V dimming. Available color temperature settings are 3500K, 4000K, and 5000K.
Adjustability and Control Options
Wattage can be set to 25W, 30W, or 40W before installation. Color temperature can be set to 3500K, 4000K, or 5000K.
The fixture supports 0-10V dimming. The selected wattage and color temperature should be consistent across a planned area when uniform appearance is required.
Longevity and Reliability
This panel light is rated for 150,000 L70 hours. It carries a 5-year warranty.
The listed operating temperature range is -4 degrees F to 122 degrees F. The integrated emergency battery backup supports emergency operation within the fixture assembly.
Build Quality and Physical Characteristics
The fixture uses an aluminum alloy housing with a white finish and a polycarbonate lens. It measures 23.75 x 47.75 x 2.25 inches and weighs 8.8 pounds.
Its 2×4 format is intended for recessed mounting. Chain-cable and surface mounting are optional configurations where the ceiling construction requires an alternate installation method.
Where This Product Fits Best
This panel light fits finished commercial interiors with 2×4 ceiling layouts and moderate general lighting requirements. Its selectable output and color settings support spaces with different visual and operational needs.
- office lighting
- healthcare facility lighting
- educational facility lighting
- conference room lighting
- corridor lighting
- reception area lighting
The aluminum housing, polycarbonate lens, and listed operating temperature range support indoor commercial installations. Fixture placement still needs to account for ceiling construction, mounting method, and the selected output setting.
Installation and Long-Term Use
Recessed mounting is the standard installation method for this 2×4 panel. Chain-cable and surface mounting options require the appropriate mounting configuration for the ceiling.
Set wattage and color temperature before final installation. Confirm the available supply voltage is within the 100-277V range and connect 0-10V control wiring only where dimming control is part of the installation.
The emergency battery backup should remain accessible for inspection and maintenance. Long-term service should include checking the lens, mounting condition, and emergency backup operation.
How This Fixture Is Commonly Used
In office lighting, healthcare facility lighting, and educational facility lighting, these panels are commonly arranged in ceiling-grid rows to maintain a consistent ceiling appearance. Recessed mounting keeps the fixture aligned with the 2×4 grid.
For conference room lighting, corridor lighting, and reception area lighting, the selected wattage is matched to the desired light level and layout. Higher output can reduce the number of fixtures in a layout, but it can also increase light levels in smaller spaces.
Mounting height affects the distribution of the 140-degree beam pattern. Layout planning should account for ceiling height, selected wattage, target light levels, and the placement of furniture or work surfaces.
Safety, Certifications, and Warranty
This fixture is UL listed and rebate eligible. It has a 5-year warranty.
The fixture operates at 100-277V and is rated for -4 degrees F to 122 degrees F. Emergency battery backup is included.
