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 LED UFO high bay is an overhead fixture for warehouse lighting, manufacturing facility lighting, distribution center lighting, and other large interior spaces with open mounting structure. It provides selectable wattage and color temperature in a compact round housing.
The fixture operates from 277-480V and produces 12,000 to 22,500 lumens. It is commonly used to replace 250W or 400W metal halide high bays where existing circuits use higher commercial or industrial voltage.
Core Performance and Output
Selectable 80W, 100W, and 150W settings provide 12,000, 15,000, and 22,500 lumens. Fixture efficacy is 150 lumens per watt, with an 80+ CRI and selectable 4000K or 5000K color temperature.
The standard 90 degree beam angle supports general overhead layouts. The higher output setting can create excessive light levels at lower mounting heights, while higher mounting heights may require closer layout review to maintain uniformity.
The fixture operates on 277-480V, 50/60Hz power and has a 0.90 power factor. A 0-10V dimming connection is provided.
Adjustability and Control Options
Wattage adjustment allows the fixture to operate at 80W, 100W, or 150W. Color temperature adjustment allows selection between 4000K and 5000K.
0-10V dimming is available for compatible control systems. A motion sensor is listed as an available feature.
Longevity and Reliability
The rated life is 50,000 L70 hours. The fixture includes 6kV surge protection.
Operating temperature is rated from -40F to 122F. The IP65 rating supports use where dust and moisture exposure are present.
Build Quality and Physical Characteristics
The UFO housing is die-cast aluminum with a black finish. A polycarbonate lens protects the optical system.
The fixture measures 10.8 inches wide by 7.7 inches high and weighs 4.5 pounds. It includes a 5-foot power cord and an 8-inch dimming cord.
Where This Product Fits Best
This fixture fits large indoor areas that use overhead high bay mounting and 277-480V electrical service. The adjustable output supports projects with different lighting levels across similar spaces.
- manufacturing facility lighting
- warehouse lighting
- distribution center lighting
- gymnasium lighting
- aircraft hangar lighting
- indoor sports facility lighting
The IP65 housing is suited to dusty or damp interior conditions within these listed applications. Final layout should account for mounting height, selected wattage, and the fixed 90 degree beam distribution.
Installation and Long-Term Use
Hook mounting is standard, with surface mounting available as an option. The compact 4.5-pound fixture can be installed where the overhead structure supports the selected mounting method.
Installers should set wattage and color temperature before final commissioning. The 277-480V input, 0-10V dimming leads, and optional motion sensor should be coordinated with the electrical and control design.
How This Fixture Is Commonly Used
In warehouse lighting, manufacturing facility lighting, and distribution center lighting, fixtures are typically arranged in overhead rows that follow the working layout and structural bays. Mounting height affects the selected wattage and the spread produced by the 90 degree beam angle.
For gymnasium lighting, aircraft hangar lighting, and indoor sports facility lighting, the layout is typically balanced across the open floor area rather than concentrated over a single location. Higher output can reduce fixture count, but it can also require more attention to glare and uniformity.
Safety, Certifications, and Warranty
This fixture is UL certified and DLC Premium certified. It is IP65 rated.
The warranty period is 5 years. Electrical work should be completed with power disconnected and in accordance with applicable installation requirements.
