How to Select the Right UFO High Bay Light for Your Facility
UFO LED high bay lights are compact, round fixtures designed for open commercial and industrial spaces with higher ceilings. They are commonly used in warehouses, manufacturing plants, gymnasiums, aircraft hangars, service bays, and distribution centers where strong downward light output and durable construction are needed.
Start by confirming that the space has an open layout and suitable mounting height, then select light output and beam angle based on the target light level, fixture spacing, and work below. Also confirm voltage, mounting method, controls, and environmental conditions. UFO high bays are often a strong fit for replacing metal halide or HPS fixtures in open high-ceiling spaces, but they are not the right fixture for every layout. With over 15 years of commercial and industrial lighting experience, LED Lighting Supply's Product Specialists help customers match UFO high bays to these requirements.
Selection and Installation Note: Product specifications, ratings, controls, certifications, and warranty coverage vary by model. Confirm the selected product specification before ordering. For code-sensitive, electrical, emergency, hazardous-location, or safety-critical applications, verify requirements with your local inspector, AHJ, or licensed electrical professional.
When UFO High Bays Are the Right Fit
UFO high bays are usually a good starting point when the space has open floor areas, higher mounting heights, and a need for strong overhead illumination. Their compact housing makes them a practical replacement for older round or pendant-mounted HID fixtures, especially in warehouses, gyms, hangars, and general industrial spaces.
| Use UFO High Bays When | Consider Another Fixture When |
|---|---|
| Ceilings are often 20 feet or higher and the space needs strong downward light output. | Ceilings are lower and a low bay, strip fixture, or troffer-style fixture would provide better comfort and distribution. |
| The layout is open, such as a warehouse floor, gymnasium, hangar, service bay, or production area. | The layout is aisle-based or row-based, where linear high bays may provide smoother coverage along racks or production lines. |
| You are replacing metal halide or HPS high bays and want instant-on performance, reduced HID lamp-and-ballast maintenance, and improved efficacy. | The area is classified as hazardous unless the selected fixture is specifically certified for the documented hazardous-location classification. |
| The environment is dusty, damp, or demanding and the selected model has appropriate enclosure, impact, temperature, and material ratings. | The area has high ambient heat, washdown, corrosion, or other special conditions that require a high-temperature, vapor-tight, corrosion-resistant, or specialty fixture verified for the exposure. |
Use the UFO high bay selector below to narrow fixtures by wattage, lumens, voltage, color temperature, controls, and mounting options.
Recommended Foot-Candles for UFO High Bay Applications
Use the tool below to find general starting foot-candle ranges by application. Final fixture selection and layout should be verified with a photometric plan, especially for larger facilities, racking layouts, sports spaces, aircraft hangars, production areas, or safety-critical applications.
Step 1: Find your foot candle levels
Step 2: Estimate your fixture count and space
UFO High Bay Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for warehouses, shops, gyms, industrial buildings, and open ceiling spaces using UFO LED high bay fixtures. 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.
Choosing UFO High Bays by Ceiling Height, Beam Angle, and Layout
UFO high bay selection starts with mounting height, target light level, beam angle, fixture spacing, and the work being performed below the fixture. The ranges below are general planning guidelines, not universal design rules. A photometric plan using the selected fixture's IES data is recommended for larger facilities, racking layouts, sports spaces, hangars, production areas, or projects where uniformity and fixture count matter.
- 20-30 foot ceilings: Projects in this range may use 100-200W UFO fixtures producing approximately 15,000-25,000 lumens with wider beam angles, depending on the target illuminance and spacing.
- 30-40 foot ceilings: Projects in this range may use 200-300W UFO fixtures producing approximately 25,000-48,000 lumens with 90 degree or 120 degree beam angles, depending on spacing, layout, and required light levels.
- 40+ foot ceilings: Often require higher-output UFO fixtures, tighter optics, or a photometric plan to confirm coverage, glare control, and uniformity.
- Open spaces: UFO high bays are commonly used for open warehouse floors, manufacturing areas, gyms, hangars, and service bays.
- Aisles and racks: Linear high bays may be a better fit where the lighting needs to follow long rows, pallet racking, or production lines.
- Dusty, damp, or demanding areas: Confirm IP rating, IK rating, operating temperature range, lens material, seals, mounting hardware, and manufacturer environmental documentation before ordering. IP and IK ratings do not by themselves establish chemical, corrosion, washdown, or hazardous-location suitability.
Tip: Keep color temperature consistent across the same room or work area. CCT describes the apparent warm or cool appearance of white light; it does not indicate brightness or color-rendering performance. Many warehouse and industrial projects use 5000K for a cooler appearance, while some commercial or mixed-use facilities prefer 4000K for a more neutral appearance.
UFO High Bay Comparisons
UFO high bays are often compared with linear high bays, low bay lights, vapor tight fixtures, explosion proof high bays, and high-temperature high bays. The right choice depends on the ceiling height, layout, environment, fixture rating, and the work being performed in the space.
| Comparison | What to Know |
|---|---|
| UFO High Bay vs Linear High Bay | UFO high bays are often well suited to open spaces and metal halide replacement. Linear high bays are often better suited to aisles, racks, production lines, and fluorescent-style replacement layouts. |
| UFO High Bay vs Metal Halide | UFO LED high bays provide instant-on operation and may offer dimming and sensor options while reducing HID lamp-and-ballast maintenance. Energy and maintenance results vary by fixture count, operating hours, controls, and existing system wattage. |
| UFO High Bay vs Low Bay | UFO high bays are generally designed for higher mounting heights. Low bay lighting is typically a better fit for lower ceilings, where high-output UFO fixtures may create glare or over-lighting. |
| UFO High Bay vs Vapor Tight | UFO high bays are selected for high-ceiling illumination and lumen output. Vapor tight fixtures are selected when a sealed construction is needed for the documented wet, dusty, or dirty exposure. Verify materials and manufacturer documentation separately for washdown, chemical, or corrosive environments. |
| UFO High Bay vs Explosion Proof | Standard UFO high bays are not a substitute for explosion proof lighting. A classified location requires fixtures certified for the documented Class, Division or Zone, Group, temperature rating, ambient conditions, voltage, and installation requirements. LED Lighting Supply can help match a fixture to an established classification but does not establish the area classification. |
| UFO High Bay vs High Temperature High Bay | Standard UFO high bays must stay within their listed operating temperature range. Hot industrial spaces such as foundries, steel mills, boiler rooms, and glass plants may require high temperature LED fixtures. |
Voltage, Controls, Mounting, and Adjustable Features
UFO high bays are available with different drivers, controls, mounting, and field-adjustable options. Confirm the selected product specification before ordering because available features vary by model.
- Voltage options: Many models support 100-277V operation, while industrial facilities may require 277-480V high bay fixtures.
- Wattage selectable models: Field-adjustable power settings can help fine-tune fixture output when permitted by the manufacturer's instructions and project design.
- CCT selectable models: Selectable 3000K, 4000K, and 5000K options can help facilities standardize color temperature across a space.
- Beam angle options: 120 degree, 90 degree, and 60 degree optics may be available, depending on fixture design and mounting height.
- Dimming: 0-10V or 1-10V dimming may be available for task-specific lighting levels and energy control.

- Mounting options: Eye hook, pendant, surface, chain, and cable suspension options may be available depending on fixture design.
Certifications, Ratings, and Warranty Support
Selected UFO high bay lights from LED Lighting Supply carry a safety listing such as UL, ETL, or CSA, depending on product. Many models are DLC or DLC Premium listed for utility rebate support, where available. DLC qualification addresses performance and efficiency criteria; it is not an electrical safety certification. Rebate requirements vary by utility, region, and product listing.
Warranty coverage varies by product, with many UFO high bay fixtures offering a 5-year warranty unless otherwise specified. Before ordering, confirm the selected product's safety certification, DLC status, voltage, controls compatibility, mounting method, environmental ratings, and warranty terms.
The Design Lights Consortium (DLC) Qualified Products List helps identify LED fixtures that meet performance criteria for energy efficiency, photometric performance, and reliability. Many utility rebate programs reference DLC listings, but requirements vary by program, region, and application.
Why Replace Metal Halide with UFO High Bays
Many UFO high bay projects involve replacing older metal halide or HPS fixtures. LED high bays can reduce HID lamp-and-ballast maintenance, improve startup performance, support dimming and sensor controls, and provide more consistent light output over their service life. Actual savings vary by existing fixture wattage, ballast draw, operating hours, utility rate, controls, and fixture count.
- Instant full output: LED fixtures reach full brightness immediately, unlike HID systems that require warm-up time.
- Reduced HID maintenance: LED fixtures avoid the routine lamp and ballast replacements associated with older HID systems, although LED drivers and other components still require maintenance or replacement if they fail.
- Control compatibility: Many LED UFO fixtures support dimming and motion sensors for additional energy savings.
- Improved light quality: LED upgrades may improve color consistency, reduce visible flicker, and remove ballast hum, depending on the selected products and existing system.
- Lower operating cost: LED conversions can reduce energy usage when properly selected and installed.
The U.S. Department of Energy reports that LED technology can significantly reduce energy consumption compared to traditional lighting. Use our lighting calculator or request a photometric plan to estimate savings, fixture count, and expected light levels for your specific facility.
