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 2×2 LED backlit panel light is a recessed ceiling fixture with adjustable wattage and adjustable color temperature. It provides selectable 20W, 30W, or 40W operation and 3500K, 4000K, or 5000K color temperature settings.
The fixture is used as a fluorescent troffer replacement in recessed commercial ceilings. Its 2×2 format, white finish, and polycarbonate lens suit finished interior ceiling layouts.
Core Performance and Output
Selectable output includes 2500, 3750, and 5000 lumens at 20W, 30W, and 40W. Fixture efficacy is 125 lumens per watt, with an 80+ CRI and a 110-degree beam angle.
The 110-degree distribution provides broad downward illumination through the panel lens. The 5000-lumen setting can be excessive in low-ceiling spaces where lower output is required.
The fixture operates on 100-277V, 50/60 Hz power. It supports 0-10V dimming.
Adjustability and Control Options
Wattage adjustment allows the fixture to operate at 20W, 30W, or 40W. Color temperature adjustment provides 3500K, 4000K, and 5000K settings.
These settings allow output and color temperature to be matched across a project before final commissioning. Wattage and color temperature should be set consistently where uniform appearance is required.
0-10V dimming is available for installations using compatible dimming controls. The fixture operates across 100-277V input voltage.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. L70 indicates the point at which light output is rated at 70 percent of initial output.
The fixture is rated for operation from -4F to 122F. Long-term performance depends on maintaining the fixture within this operating temperature range.
Build Quality and Physical Characteristics
The panel uses an aluminum alloy housing and a polycarbonate lens. The housing is finished in white for recessed ceiling installation.
Fixture dimensions are 23.78 inches long by 23.78 inches wide by 1.3 inches high. Fixture weight is 4.5 pounds.
Recessed mounting is the listed installation method. The low-profile housing is intended for 2×2 recessed ceiling locations.
Where This Product Fits Best
This panel light fits finished commercial interior spaces with recessed 2×2 ceiling grids and moderate general lighting requirements. Its selectable output and color temperature support spaces that need different lighting settings within the same fixture format.
- office lighting
- commercial interior lighting
- educational facility lighting
- healthcare facility lighting
- conference room lighting
- retail interior lighting
- corridor lighting
The recessed form factor is suited to interior ceilings rather than exposed industrial mounting conditions. The -4F to 122F operating range should be maintained at the installed ceiling location.
Installation and Long-Term Use
The fixture installs recessed in a 2×2 ceiling location. Verify ceiling grid condition, available plenum depth, branch voltage, and 0-10V control wiring where dimming is required.
Set wattage and color temperature before final commissioning. Maintaining the same settings across connected ceiling areas avoids visible differences in output and color appearance.
Access to the recessed fixture should remain available for future inspection or replacement. The aluminum alloy housing and polycarbonate lens should be kept free of damage during ceiling work.
How This Fixture Is Commonly Used
In office lighting, commercial interior lighting, healthcare facility lighting, and educational facility lighting, the panel is laid out in recessed ceiling grids as part of a regular room lighting pattern. Mounting height follows the finished ceiling height and recessed grid location.
Conference room lighting, retail interior lighting, and corridor lighting commonly use repeated fixture rows or evenly distributed grid positions. Layout patterns are typically aligned with ceiling tiles, room geometry, and target light levels.
Spacing varies with the selected wattage, ceiling height, target light level, and room layout. Higher output can reduce fixture count, but it may create more brightness than required in smaller areas.
Safety, Certifications, and Warranty
This fixture is ETL certified. It is rebate eligible.
The fixture includes a 5-year warranty. It is rated for 100-277V, 50/60 Hz operation.

Application Questions and Clarification
Q: Is this fixture appropriate for office lighting and conference room lighting?
A: Office lighting and conference room lighting are listed applications for this panel light. The recessed 2×2 format, adjustable output, and adjustable color temperature should be reviewed against the ceiling layout and required light level.
Q: What should be verified for commercial interior lighting installation?
