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 and color adjustable recessed fixture for office lighting, educational facility lighting, healthcare facility lighting, and commercial interior lighting. It provides selectable 30W, 40W, or 50W output and selectable 3500K, 4000K, or 5000K color temperature.
The fixture replaces fluorescent troffers where a recessed 2×4 panel format is required. Its 110-degree distribution and polycarbonate lens provide broad general illumination across the ceiling plane.
Core Performance and Output
Selectable output settings produce 3,750, 5,000, or 6,250 lumens at 125 lumens per watt. The 80+ CRI configuration is available with 3500K, 4000K, and 5000K color temperature settings.
The standard 110-degree beam distribution is intended for broad interior coverage. The 100-277V driver operates on 50/60 Hz power and supports 0-10V dimming.
The 50W setting can be excessive in lower-light interior layouts. Final output selection should account for mounting height, existing fixture layout, and target light levels.
Adjustability and Control Options
Wattage is adjustable between 30W, 40W, and 50W. Color temperature is adjustable between 3500K, 4000K, and 5000K.
The fixture supports 0-10V dimming. Adjustment settings allow the same panel format to be configured for different interior lighting conditions without changing the fixture body.
Longevity and Reliability
The panel is rated for 50,000 hours L70 life. It carries a 5-year warranty.
The listed operating temperature range is -4F to 122F. Long-term performance depends on maintaining the fixture within this operating range.
Build Quality and Physical Characteristics
The fixture uses an aluminum alloy housing with a white finish and a polycarbonate lens. It measures 47.81 inches long by 23.78 inches wide by 1.3 inches high and weighs 7 pounds.
Recessed mounting is standard. Chain-cable and surface mounting are optional configurations.
Where This Product Fits Best
This panel light fits enclosed commercial interiors that use recessed 2×4 fixtures for general lighting. Its adjustable output and color temperature support spaces with different interior lighting requirements.
- office lighting
- educational facility lighting
- healthcare facility lighting
- commercial interior lighting
- conference room lighting
- corridor lighting
The aluminum housing and polycarbonate lens are suited to the stated -4F to 122F operating temperature range. Recessed mounting should match the installed ceiling configuration.
Installation and Long-Term Use
Recessed mounting is the standard installation method. Chain-cable and surface mounting are available where the selected installation configuration requires them.
Set wattage and color temperature before final commissioning so fixtures remain consistent across the layout. Verify supply voltage, dimming wiring, mounting method, and access for future maintenance before installation.
How This Fixture Is Commonly Used
In office lighting, educational facility lighting, healthcare facility lighting, and commercial interior lighting, these panels are laid out in repeated recessed rows to provide broad, even general illumination. Conference room lighting and corridor lighting layouts commonly follow the room shape and ceiling fixture pattern.
Mounting height and fixture spacing should be evaluated with the target light level and existing layout. Higher output can reduce the number of fixtures required, but it can also increase light levels within the space.
Safety, Certifications, and Warranty
This fixture is ETL listed and rebate eligible.
The fixture is rated for 100-277V operation and 0-10V dimming. Warranty coverage is 5 years.
