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 1×4 LED troffer light is a recessed panel fixture with adjustable wattage and adjustable color temperature. It provides 1890 to 3700 lumens for interior ceiling lighting where output and color temperature need to be set during installation.
The fixture is designed to replace fluorescent troffers in office lighting, commercial interior lighting, healthcare facility lighting, and educational facility lighting. Its recessed format maintains a flush ceiling appearance in compatible 1×4 ceiling systems.
Core Performance and Output
Selectable wattage settings include 14W, 17W, 20W, and 28W. Corresponding output levels are 1890, 2360, 2750, and 3700 lumens, with efficacy rated at 132 lumens per watt.
The standard 120 degree beam distribution provides broad downward light through a polycarbonate lens. Higher output settings should be matched to ceiling height, target light levels, and layout requirements to avoid excessive light at lower mounting heights.
The fixture operates on 100-277V, 50/60Hz power and supports 0-10V dimming. CRI is rated at 80+.
Adjustability and Control Options
Wattage is adjustable from 14W through 28W. This allows output selection from 1890 to 3700 lumens without changing the fixture.
Color temperature is adjustable between 3000K, 3500K, 4000K, 5000K, and 6500K. The selected color temperature should remain consistent across a finished lighting area.
0-10V dimming is provided for installations using compatible dimming controls. Dimming wiring and control configuration should be verified during installation.
Longevity and Reliability
This LED troffer is rated for a 50,000-hour lifespan. The operating temperature range is -4F to 122F.
Selectable wattage and color temperature settings allow fixture configuration before the ceiling installation is completed. Settings should be confirmed before the fixture is placed into service.
Build Quality and Physical Characteristics
The fixture uses an aluminum alloy housing, white finish, and polycarbonate lens. It measures 47.8 inches long, 11.75 inches wide, and 2 inches high.
Fixture weight is 7.7 pounds. Recessed mounting is specified for this 1×4 troffer configuration.
Where This Product Fits Best
This recessed 1×4 troffer is suited to interior applications that use compatible ceiling systems and require broad, evenly distributed general lighting.
- office lighting
- commercial interior lighting
- educational facility lighting
- healthcare facility lighting
- conference room lighting
- corridor lighting
- reception area lighting
The adjustable color temperature and wattage settings support projects where light appearance and output need to be aligned with the finished interior area. Recessed installation requires a compatible 1×4 ceiling opening and ceiling system.
Installation and Long-Term Use
The fixture is installed recessed in a compatible 1×4 ceiling system. Confirm ceiling opening dimensions, fixture support, branch voltage, and dimming connections before installation.
Long-term maintenance access depends on the ceiling layout and access above the ceiling plane. The 100-277V input range and 0-10V dimming connections should be identified before energizing the fixture.
How This Fixture Is Commonly Used
In office lighting, educational facility lighting, and healthcare facility lighting, these troffers are typically arranged in ceiling grids to create consistent general illumination across the occupied area. Recessed mounting keeps the fixture aligned with the ceiling plane.
In commercial interior lighting, corridor lighting, conference room lighting, and reception area lighting, layout patterns follow ceiling grid spacing and the required light distribution. Fixture spacing varies with ceiling height, selected wattage, target light levels, and the 120 degree beam distribution.
Safety, Certifications, and Warranty
This fixture is UL certified. It is rebate eligible.
The warranty period is 5 years. The fixture is rated for operation from -4F to 122F.
