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 is designed for high-ceiling interior lighting where broad, high-output coverage is needed. It provides selectable wattage, selectable color temperature, and a 90-degree beam distribution in a white linear housing.
The fixture operates from 240, 270, or 310 watts and is listed as a replacement for 1000 watt metal halide fixtures. Its chain-cable mounting configuration supports suspended installations, with pendant and surface mounting options available.
Core Performance and Output
Output ranges from 36,000 to 46,500 lumens across the three selectable wattage settings. Fixture efficacy is 150 lumens per watt, with 80+ CRI and selectable 4000K or 5000K color temperature.
The standard 90-degree beam angle provides a broad distribution suited to open high-ceiling layouts and aisle-oriented layouts. The higher output settings can be excessive at lower mounting heights, while higher mounting elevations require layout review to maintain uniformity.
Input voltage is available in 100-277V or 277-480V configurations. The fixture operates at 50/60 Hz with a minimum 0.90 power factor and 20% maximum THD.
Adjustability and Control Options
Wattage adjustment provides 240W, 270W, and 310W operating settings. Color temperature adjustment provides 4000K and 5000K settings.
0-10V dimming is supported. Motion sensor and emergency backup battery features are available.
The default motion sensor configuration uses a 100% detection area, 30-second hold time, 60-second standby period, and 10% standby dimming level. A motion sensor remote control is required to change the default sensor settings.
Longevity and Reliability
The LED system is rated for 50,000 hours at L70. The operating temperature range is -40 degrees F to 122 degrees F.
Integrated 10kV surge protection supports electrical reliability. The fixture carries a 5-year warranty.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a polycarbonate lens. The fixture has a white finish.
Fixture dimensions are 20.5 inches long by 11.54 inches wide by 2.13 inches high. Fixture weight is 10 pounds.
The standard mounting method is chain-cable mounting. Pendant and surface mounting are optional, and no cord is included.
Where This Product Fits Best
This linear high bay fits interior facilities with elevated ceilings, continuous work areas, storage areas, and aisle-based layouts. Its output range is suited to applications that need high fixture output from a compact linear form factor.
- warehouse aisle lighting
- distribution center lighting
- manufacturing facility lighting
- retail warehouse lighting
- storage facility lighting
- commercial interior high ceiling lighting
The selectable voltage, wattage, and color temperature settings support projects with differing electrical systems and lighting requirements. Final fixture placement should account for mounting elevation, target light levels, and the fixed 90-degree beam angle.
Installation and Long-Term Use
Chain-cable mounting is the standard suspension method. Pendant and surface mounting options allow the fixture to be configured for different ceiling structures and installation approaches.
Installers must select the correct voltage configuration before installation. The fixture has no attached cord, so field wiring must be completed at the mounting location.
For long-term operation, the selectable wattage and color temperature settings should be established during commissioning. Motion sensor settings remain at their default configuration unless changed with the required remote control.
How This Fixture Is Commonly Used
In warehouse aisle lighting, the linear fixture is typically aligned with the aisle direction to place light along the travel and storage path. Distribution center lighting and storage facility lighting layouts commonly use repeated fixture rows across larger interior areas.
Manufacturing facility lighting and retail warehouse lighting layouts are typically arranged around ceiling structure, work areas, and open floor patterns. Mounting height affects both the illuminated area and the fixture output setting selected for the layout.
Higher wattage settings can reduce the number of fixtures in a layout, but spacing and light distribution must still be reviewed against the required light levels. The supplied product data does not establish a fixed mounting height or spacing value.
Safety, Certifications, and Warranty
UL listed. DLC Premium listed.
The fixture includes 10kV surge protection and is rated for operation from -40 degrees F to 122 degrees F. Warranty coverage is 5 years.
