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 selectable 240W, 270W, or 310W output with selectable 4000K or 5000K color temperature. It is built for high-ceiling interior lighting where a linear fixture form factor and broad 90 degree distribution are required.
The fixture delivers up to 46,500 lumens and replaces 1000W metal halide fixtures. Chain-cable mounting is standard, with pendant and surface mounting available.
Core Performance and Output
Output settings are 36,000, 40,500, and 46,500 lumens at 150 lumens per watt. The standard 90 degree beam distribution supports broad light spread from a linear high bay layout.
The fixture operates on 100-277V or 277-480V power at 50/60Hz. Power factor is 0.90 and THD is 20% maximum.
The 46,500-lumen setting can produce excessive light at lower mounting heights. Higher mounting heights require layout review to maintain uniformity with the fixed 90 degree beam angle.
Adjustability and Control Options
Wattage and color temperature are adjustable at the fixture. Available color temperatures are 4000K and 5000K.
0-10V dimming is supported. A motion sensor and emergency backup battery are available features.
The motion sensor default configuration uses 100% detection area, a 30-second hold time, a 60-second standby period, and 10% standby dimming. A motion sensor remote control is required to change default sensor settings.
Longevity and Reliability
Rated life is 50,000 hours at L70. The fixture operates from -40F to 122F.
Built-in 10kV surge protection supports electrical reliability in commercial and industrial electrical systems. Long-term performance depends on maintaining suitable ambient temperature and electrical conditions.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a white finish. A polycarbonate lens protects the optical system.
Fixture dimensions are 20.5 inches long, 11.54 inches wide, and 2.13 inches high. Fixture weight is 10 pounds.
No cord is included. Standard mounting is chain-cable, with pendant and surface mounting available.
Where This Product Fits Best
This linear high bay fits interior high-ceiling applications requiring high output, selectable wattage, and 100-277V or 277-480V operation. The linear form factor is commonly used where fixture rows follow aisles, equipment lines, storage rows, or open interior layouts.
- distribution center lighting
- warehouse aisle lighting
- manufacturing facility lighting
- retail warehouse lighting
- storage facility lighting
- commercial interior high ceiling lighting
The -40F to 122F operating range supports demanding interior temperature conditions. Final placement should account for mounting height, target light levels, and the 90 degree beam distribution.
Installation and Long-Term Use
Chain-cable mounting is the standard installation method. Pendant and surface mounting are available when the building structure or ceiling layout requires a different fixture position.
Installers should confirm supply voltage before installation because this fixture is available in 100-277V and 277-480V versions. No cord is included with the fixture.
For motion sensor installations, default settings are active unless changed with the required sensor remote control. Access for future cleaning, adjustment, and maintenance should be considered during fixture placement.
How This Fixture Is Commonly Used
In warehouse aisle lighting and distribution center lighting layouts, fixtures are commonly arranged in rows that follow aisle direction. Mounting height and aisle geometry determine final fixture placement.
Manufacturing facility lighting layouts commonly use rows aligned with work areas and equipment lines. Retail warehouse lighting and storage facility lighting layouts may use more open row patterns based on the interior arrangement.
Higher output can reduce fixture count, but it can also increase brightness at lower mounting heights. Spacing varies with the selected wattage, mounting height, target light levels, and layout requirements.
Safety, Certifications, and Warranty
UL listed. DLC Premium listed.
The fixture includes 10kV surge protection. Warranty coverage is 5 years.
