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 UFO high bay produces 45,000 lumens with a 5000K color temperature and a 120 degree beam angle. It is configured for high-output indoor lighting where broad downward distribution is needed from a compact round fixture.
The fixture operates on 277-480V power and includes 1-10V dimming. Its 45,000-lumen output is listed as a replacement for 1000 watt metal halide fixtures in existing high-bay layouts.
The die-cast aluminum housing, tempered glass lens, IP65 rating, and IK08 impact rating support demanding indoor installations where dust, moisture, and incidental impact are concerns.
Core Performance and Output
This UFO high bay delivers 45,000 lumens at 300 watts, producing 150 lumens per watt. The 5000K light output and 70+ CRI are suited to spaces that need clear general illumination and visibility across large open areas.
The standard 120 degree beam angle creates a broad distribution pattern. Layouts need to account for overlap between fixtures to maintain uniform light levels across the area.
The fixture operates at 277-480V, 50/60Hz, with a 0.90 power factor and maximum 20% THD. At lower mounting heights, 45,000 lumens can create excessive brightness if fixture spacing and dimming are not addressed.
Adjustability and Control Options
1-10V dimming is included for light-level adjustment. The dimming lead is 8 inches long.
Eye-hook mounting is standard. Pendant mounting is available as an option where the fixture needs to be suspended below the mounting structure.
Longevity and Reliability
The rated L70 lifespan is 164,000 hours. This rating identifies the point at which light output is expected to reach 70 percent of initial output.
The fixture is rated for operation from -22F to 122F. Long-term performance depends on maintaining the housing, lens, wiring, and mounting connection in serviceable condition.
Build Quality and Physical Characteristics
The fixture uses a black die-cast aluminum housing with a tempered glass lens. The housing is IP65 rated and IK08 rated.
Overall dimensions are 16 inches wide by 8 inches high. Fixture weight is 21 pounds.
A 5-foot power cord is included. A dome accessory is available.
Where This Product Fits Best
This high-output UFO fixture fits large indoor spaces with elevated mounting structures and open lighting layouts. Its 45,000-lumen output and 120 degree distribution align with broad-area high-bay lighting requirements.
- distribution center lighting
- manufacturing facility lighting
- warehouse lighting
- aircraft hangar lighting
- gymnasium lighting
- indoor sports facility lighting
The IP65 and IK08 ratings support locations where dust, moisture exposure, and incidental impact are part of normal operating conditions. Fixture placement should account for mounting height, reflective surfaces, target light levels, and glare control.
Installation and Long-Term Use
Install the fixture using the standard eye-hook mount or the optional pendant mount. The mounting point and supporting structure must carry the 21-pound fixture weight.
Use the 277-480V input range when confirming electrical compatibility. Keep the power cord and dimming lead accessible for connection and future service.
For long-term use, inspect the eye-hook connection, lens, housing, and wiring during routine maintenance. Accumulated dirt on the tempered glass lens can reduce delivered light.
How This Fixture Is Commonly Used
In warehouse lighting, manufacturing facility lighting, and distribution center lighting, this fixture is typically arranged in regular rows that follow the building structure and work area layout. The broad 120 degree beam supports overlapping light patterns across open floor areas.
For gymnasium lighting, indoor sports facility lighting, and aircraft hangar lighting, fixtures are positioned to provide broad general illumination while managing direct brightness from the 45,000-lumen output. Mounting height and fixture alignment affect glare and uniformity.
Higher output can reduce fixture count, but wider spacing can reduce uniformity between fixtures. 1-10V dimming can be used where the installed output needs adjustment.
Safety, Certifications, and Warranty
UL listed. DLC Premium listed.
The fixture has an IP65 rating and IK08 rating. Operating temperature range is -22F to 122F.
Warranty coverage is 5 years.
