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 300 watt LED linear high bay produces 40,800 lumens for high-ceiling interior lighting layouts. The 4 foot fixture uses a frosted lens and 110 degree beam distribution to provide broad illumination across aisles and open work areas.
The fixture operates on 277-480V power and includes selectable 4000K or 5000K color temperature. It can replace a 1000 watt metal halide fixture where the existing layout and light levels support the conversion.
Core Performance and Output
The fixture delivers 136 lumens per watt with an 80+ CRI. Its 110 degree beam angle supports broad distribution from a linear form factor, while the frosted lens reduces direct view of the LED source.
Electrical performance includes 277-480V operation, 50/60Hz frequency, 0.98 power factor, and THD of 20% maximum. The 40,800-lumen output can be excessive at lower mounting heights where lower output fixtures or closer control of glare may be required.
At higher mounting heights, fixture layout and spacing affect uniformity between rows and along aisles. Final placement should account for mounting height, target light levels, obstructions, and the direction of the aisle or work area.
Adjustability and Control Options
The fixture has selectable 4000K and 5000K color temperature settings. This allows the installed fixture color temperature to match the visual requirements of the space.
0-10V dimming is included. Dimming controls can be used where the connected control system is designed for 0-10V operation.
Longevity and Reliability
The rated L70 lifespan is 200,000 hours. This rating identifies the point at which output is expected to reach 70 percent of initial light output.
The operating temperature range is -22F to 113F. The fixture includes a 5-year warranty.
Build Quality and Physical Characteristics
The housing is galvanized rolled iron with a white finish. Fixture dimensions are 46.5 inches long by 18.9 inches wide by 2.2 inches high.
The fixture weighs 18 pounds and has no attached cord. Standard mounting is chain-cable mounting, with pendant and surface mounting available as options.
Where This Product Fits Best
This linear high bay fits interior high-ceiling spaces that use row-based layouts, aisle lighting patterns, or broad open-area illumination. Its 40,800-lumen output and 4 foot linear form are suited to larger interior lighting zones.
- warehouse aisle lighting
- distribution center lighting
- manufacturing facility lighting
- retail warehouse lighting
- storage facility lighting
- commercial interior high ceiling lighting
The fixture operates from 277-480V and is rated for temperatures from -22F to 113F. The frosted lens and 110 degree beam pattern support broad light distribution where fixture rows are arranged around building geometry and work zones.
Installation and Long-Term Use
Chain-cable mounting is the standard installation method. Pendant and surface mounting are available where the building structure and fixture layout require those mounting methods.
Verify mounting support, branch voltage, dimming wiring, and fixture orientation before installation. The fixture has no attached cord, so field wiring must be planned for the selected mounting method.
How This Fixture Is Commonly Used
In warehouse aisle lighting and distribution center lighting, fixtures are typically arranged in rows that follow aisle direction and storage layout. Mounting height should be evaluated with the required light levels and the vertical clearance of the space.
For manufacturing facility lighting, retail warehouse lighting, storage facility lighting, and commercial interior high ceiling lighting, layouts are commonly based on work zones, open floor areas, and structural bay spacing. Higher output can reduce fixture count, but spacing and mounting height still determine uniformity and glare control.
Safety, Certifications, and Warranty
This fixture is UL listed and rebate eligible. It operates on 277-480V electrical systems.
The fixture includes a 5-year warranty. Installation should follow applicable electrical requirements and the selected mounting configuration.
