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 150 Watt LED UFO high bay produces 21,700 lumens at 5000K for high-bay interior lighting. Its round die-cast aluminum housing, polycarbonate lens, and hook mount support open-ceiling installations.
The fixture operates on 277-480V power and is listed as a replacement for 400 or 1000 Watt metal halide fixtures. It is commonly configured for warehouse lighting, manufacturing facility lighting, and distribution center lighting.
Core Performance and Output
The fixture delivers 145 lumens per watt with a 120-degree beam distribution and 80+ CRI. The wide distribution supports broad general illumination patterns rather than narrow aisle-focused lighting.
It operates at 50/60 Hz with a 0.90 power factor and THD of 20% maximum. At lower mounting heights, 21,700 lumens can produce excessive brightness unless the layout and dimming level are controlled.
The 120-degree optic provides wide coverage, but uniformity decreases when fixture spacing is extended beyond the lighting plan. Higher mounting positions require layout review to maintain target light levels.
Adjustability and Control Options
This UFO high bay includes 0-10V dimming capability. The dimming cord is 8 inches long.
A motion sensor is available for occupancy-based control. A dome accessory is also available.
Longevity and Reliability
The rated life is 50,000 L70 hours. The fixture includes 4kV surge protection.
Operating temperature range is -40F to 113F. The IP65 rating and IK10 impact rating support use in demanding interior environments where dust and incidental impact are concerns.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a black finish. A polycarbonate lens protects the optical assembly.
The fixture measures 11.6 inches wide by 8.5 inches high and weighs 10 pounds. It includes a 5-foot cord.
Where This Product Fits Best
This UFO high bay fits open, high-ceiling interior spaces requiring broad general illumination from a compact round fixture. Its 277-480V input supports facilities with higher-voltage electrical systems.
- warehouse lighting
- manufacturing facility lighting
- distribution center lighting
- gymnasium lighting
- aircraft hangar lighting
- indoor sports facility lighting
The IP65-rated housing, IK10 impact rating, and -40F to 113F operating range support installations exposed to dust, temperature changes, and incidental physical contact.
Installation and Long-Term Use
Hook mounting is standard, with surface mounting available as an option. Verify the mounting structure, fixture weight, supply voltage, and cord routing before installation.
0-10V dimming wiring should be planned separately from the 277-480V power connection. Motion sensor selection and placement should be established before final commissioning.
How This Fixture Is Commonly Used
In warehouse lighting, manufacturing facility lighting, and distribution center lighting, the fixture is typically suspended from the ceiling structure in a grid or row layout. Mounting height is determined by the ceiling structure, required light levels, and the 120-degree distribution.
For gymnasium lighting, aircraft hangar lighting, and indoor sports facility lighting, fixtures are arranged to control brightness across the active area. Higher output can reduce fixture count, but spacing and dimming settings affect uniformity and glare.
Safety, Certifications, and Warranty
UL listed. DLC Premium listed.
IP65 rated. IK10 rated.
This fixture includes a 5-year warranty.
