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.
With over 15 years of commercial and industrial lighting experience, LED Lighting Supply’s Product Specialists help customers match UFO high bays to ceiling height, lumen requirements, beam angle, 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.
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 or a licensed electrical professional.
When UFO High Bays Are the Right Fit
UFO high bays are usually the best 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 typically 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 maintenance, and improved efficiency. | The area is classified as hazardous unless the selected fixture is specifically rated for the required hazardous-location classification. |
| The environment is dusty, damp, or demanding and the selected model has the right IP, IK, and operating temperature 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. |
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
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. A photometric plan is recommended for larger facilities, racking layouts, sports spaces, hangars, production areas, or projects where uniformity and fixture count matter.
- 20-30 foot ceilings: Often use 100-200W UFO fixtures producing approximately 15,000-25,000 lumens with wider beam angles.
- 30-40 foot ceilings: Often use 200-300W UFO fixtures producing approximately 25,000-48,000 lumens with 90 degree or 120 degree beam angles depending on spacing and layout.
- 40+ foot ceilings: Often require higher-output UFO fixtures, tighter beam angles, or a photometric plan to confirm coverage 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, and mounting hardware before ordering.
Tip: Keep color temperature consistent across the same room or work area. Many warehouse and industrial projects use 5000K for visibility, while some commercial or mixed-use facilities prefer 4000K for a softer 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 usually better for open spaces and metal halide replacement. Linear high bays are often better for aisles, racks, production lines, and fluorescent-style replacement layouts. |
| UFO High Bay vs Metal Halide | UFO LED high bays provide instant-on operation, reduced maintenance, dimming and sensor options, and improved efficiency compared to older HID systems. Results vary by fixture count, operating hours, controls, and existing system wattage. |
| UFO High Bay vs Low Bay | UFO high bays are 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 the environment requires sealed construction for wet, dusty, dirty, washdown, or corrosive conditions. |
| UFO High Bay vs Explosion Proof | Standard UFO high bays are not a substitute for explosion proof lighting. Classified hazardous locations require properly rated fixtures based on Class, Division, Group, T-rating, voltage, mounting method, and installation environment. |
| 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. |

Common UFO High Bay Mistakes and How to Avoid Them
- Undersizing fixtures for the ceiling height: Too little output or the wrong beam angle can leave dark spots. Use ceiling height, fixture spacing, and target foot-candles as starting points, then verify larger projects with photometrics.
- Using UFO fixtures where linear high bays fit better: UFO high bays work well in open areas, but linear fixtures may perform better over aisles, racks, production lines, and rectangular layouts.
- Choosing the wrong beam angle: Wider beam angles are often used at lower high-bay mounting heights, while higher ceilings may need tighter optics to deliver light to the work plane.
- Ignoring voltage compatibility: Verify 120V, 277V, or 480V requirements before ordering to avoid driver, installation, or safety issues.
- Skipping environmental ratings: Dusty, wet, washdown, corrosive, high-temperature, or classified areas may require specialty fixtures instead of standard UFO high bays.
- Adding motion sensors without reviewing detection patterns: Sensor type, mounting height, timeout settings, and detection patterns affect how well controls perform in real facilities.
