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 adjustable linear LED high bay provides 320W, 400W, or 500W operation from one 3-foot 4-inch fixture. It supports 3500K, 4000K, and 5000K color temperature selection for high-ceiling interior lighting layouts.
The fixture is configured for warehouse aisle lighting, manufacturing facility lighting, and distribution center lighting where high output and broad 120-degree distribution are required. Its 500W setting replaces a 1500W metal halide fixture.
Core Performance and Output
Output ranges from 48,960 to 76,900 lumens, with 150 lumens per watt across the available wattage settings. The standard 120-degree beam angle supports broad distribution from a linear fixture form factor.
The fixture operates on 100-277V, 50/60Hz power with a 0.90 power factor and 20 percent maximum THD. The higher output settings can be excessive where lower mounting heights or lower target light levels apply.
At higher mounting heights, fixture layout and target light levels affect uniformity. The 1-10V dimming capability allows output reduction where the installed wattage setting produces more light than required.
Adjustability and Control Options
Field-adjustable wattage settings include 320W, 400W, and 500W. Color temperature is adjustable between 3500K, 4000K, and 5000K.
The fixture supports 1-10V dimming. Wattage selection, color temperature selection, and dimming setup should be completed before final commissioning.
Longevity and Reliability
This linear high bay is rated for 100,000 hours L70 life. The operating temperature range is -22F to 122F.
Long-term performance depends on correct mounting, electrical connections, and access for maintenance. The fixture has a 5-year warranty.
Build Quality and Physical Characteristics
The housing is aluminum alloy with a white finish. Fixture dimensions are 39.5 inches long, 12 inches wide, and 2 inches high.
The fixture weighs 14.6 pounds. It has no cord and requires field wiring.
Where This Product Fits Best
This fixture fits high-ceiling interior layouts requiring high output, adjustable wattage, and a linear distribution pattern. It is suited to facilities using continuous rows or organized aisle layouts.
- warehouse aisle lighting
- distribution center lighting
- manufacturing facility lighting
- retail warehouse lighting
- storage facility lighting
- commercial interior high ceiling lighting
The aluminum alloy housing and -22F to 122F operating range support interior environments within the stated temperature range. Chain-cable mounting is standard, with surface mounting available as an option.
Installation and Long-Term Use
Chain-cable mounting is the standard installation method. Surface mounting is available where the mounting structure supports the fixture and the layout requires a fixed close-to-ceiling position.
Confirm the 100-277V supply, fixture weight, mounting attachment points, and field wiring route before installation. The fixture has no factory cord.
For long-term use, retain access to wattage and color temperature settings where adjustments may be required. Verify 1-10V control wiring when dimming is part of the installation.
How This Fixture Is Commonly Used
In warehouse aisle lighting and distribution center lighting, fixtures are commonly arranged in rows that follow aisle direction and storage layout. Mounting height and target light levels determine the final row spacing and wattage setting.
For manufacturing facility lighting, the linear form factor supports organized fixture layouts over work areas and equipment zones. Higher output can reduce fixture count, but layout must still control uniformity and glare.
Retail warehouse lighting, storage facility lighting, and commercial interior high ceiling lighting layouts typically use the selected color temperature and wattage setting to match the space lighting plan. Final placement depends on the mounting height and required light levels.
Safety, Certifications, and Warranty
UL listed. Rebate eligible.
The fixture operates from 100-277V and supports 1-10V dimming. Installation must account for the fixture’s 14.6-pound weight and field wiring requirement.
The warranty is 5 years.
