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 270W, 340W, or 400W operation with selectable 4000K or 5000K color temperature. It is built for high-ceiling interior lighting layouts using a linear fixture form factor.
The fixture produces 41,600 to 56,100 lumens and is listed as a replacement for 1000W, 1500W, or 2000W metal halide fixtures. Chain-cable mounting is standard, with pendant and surface mounting options available.
Core Performance and Output
Output is selectable at 41,600, 50,000, or 56,100 lumens, depending on the wattage setting. Efficacy is 150 lumens per watt, with an 80+ CRI and a standard 90-degree beam angle.
The fixture operates on 100-277V at 50/60 Hz. Power factor is 0.98 and THD is 20% maximum. The higher output settings can be excessive where mounting heights are low or where lower light levels are required.
Adjustability and Control Options
Wattage is adjustable between 270W, 340W, and 400W. Color temperature is adjustable between 4000K and 5000K.
0-10V dimming is included. Dimming control wiring and control compatibility should be confirmed before installation.
Longevity and Reliability
This linear high bay has a listed lifespan of 70,000 hours. The five-year warranty covers the fixture.
The operating temperature range is -4 degrees F to 122 degrees F. Long-term performance depends on maintaining connections, mounting hardware, and control wiring.
Build Quality and Physical Characteristics
The housing is galvanized rolled iron with a white finish. A polycarbonate lens protects the optical system.
The fixture measures 44.2 inches long by 10.2 inches wide by 1.8 inches high and weighs 10 pounds. It has no cord and requires field wiring.
Where This Product Fits Best
This linear high bay fits interior high-ceiling layouts that need broad, consistent coverage along aisles, work areas, storage areas, or open commercial spaces.
- warehouse aisle lighting
- distribution center lighting
- manufacturing facility lighting
- retail warehouse lighting
- storage facility lighting
- commercial interior high ceiling lighting
The 100-277V input, chain-cable mounting, and selectable output support projects where fixture placement and light level requirements vary across the layout.
Installation and Long-Term Use
Chain-cable mounting is standard. Pendant and surface mounting are optional. Mounting hardware and support structure must carry the 10-pound fixture weight.
Installers need to provide field wiring because the fixture has no cord. Wattage and color temperature should be set before commissioning, and 0-10V control wiring should be separated and terminated correctly.
How This Fixture Is Commonly Used
In warehouse aisle lighting and distribution center lighting, linear high bays are typically arranged in rows that follow aisle direction and storage layout. In manufacturing facility lighting, placement follows equipment, work areas, and required light distribution.
Mounting height affects fixture spacing, output selection, and uniformity. Higher output can reduce fixture count, but layout requirements and target light levels still determine final spacing.
Safety, Certifications, and Warranty
UL certified. Rebate eligible.
The fixture has a five-year warranty. Operating temperature is rated from -4 degrees F to 122 degrees F.
Frequently Asked Questions
Q: What wattage settings are available?
A: The fixture is adjustable between 270W, 340W, and 400W.
Q: What lumen outputs does this linear high bay produce?
A: It produces 41,600, 50,000, or 56,100 lumens, depending on the selected wattage.
Q: Can the color temperature be changed?
A: Yes. The fixture has selectable 4000K and 5000K color temperature settings.
Q: What mounting options are available?
A: Chain-cable mounting is standard. Pendant and surface mounting are optional.
Q: What determines fixture layout for warehouse aisle lighting?
A: Mounting height, target light levels, aisle layout, and the selected wattage affect fixture placement. A specific spacing value is not established by the supplied product data.
Application Questions and Clarification
Q: Is this fixture appropriate for distribution center lighting?
A: Distribution center lighting is a primary application for this linear high bay. Final fixture placement depends on mounting height, layout requirements, and selected output.
Q: What should be confirmed for manufacturing facility lighting?
A: Confirm the available 100-277V supply, mounting method, target light levels, and whether 0-10V dimming is required.
Q: Can this fixture be used for commercial interior high ceiling lighting?
A: Commercial interior high ceiling lighting is a listed secondary application. The selected wattage and 90-degree beam distribution should match the planned layout.
