High-ceiling spaces demand bright, uniform, and efficient lighting. LED UFO high bay lights (aka round high bay, industrial high bay) deliver more lumens per watt, slash maintenance time, and improve visibility and safety—making them ideal for warehouse lighting, factory lighting, and gym lighting.
What are LED UFO High Bay Lights?
UFO high bays are compact, round, one-piece fixtures designed for ceilings typically 20–50 ft (6–15 m). With precision optics and robust thermal design, they provide wide, even illumination from fewer fixtures and work well in open bays, rack aisles, and sports courts.
Common applications:
- Warehouses and distribution centers
- Manufacturing plants and workshops
- Gyms, basketball courts, and indoor sports arenas
- Big-box retail, exhibition halls, airplane hangars
Best-fit applications and quick recommendations
- Warehouses and logistics
Goals: High uniformity, low glare, minimal maintenance
Tip: 60°/90° beams for high rack aisles; 90°/120° for open areas
Controls: Occupancy/microwave sensors and daylight harvesting for extra savings
- Factories and production floors
Goals: Adequate task illuminance, low flicker, better visual comfort
Tip: Target 300–500 lux for general tasks; higher for precision work; consider 4000K for long-shift comfort
- Gyms and sports facilities
Goals: Uniform light, high brightness, controlled glare
Tip: 120° wide beam; 5000K for crisp, high-contrast visibility; confirm UGR/glare control
How to choose the right UFO High Bay (fast guide)
- Mounting height vs. power (rule-of-thumb)
20–26 ft (6–8 m): typically 100–150W
30–40 ft (9–12 m): typically 150–200W
40–50 ft (12–15 m): typically 200–240W
Note: Final selection depends on reflectance, target lux/foot-candles, and beam angle.
- Fixture spacing
Start with 0.8–1.2 × mounting height (e.g., 10 m height → 8–12 m spacing) and refine with a layout.
- Beam angle
Aisles and high racks: 60°/90°
Open floors and sports: 90°/120°
- Color temperature and CRI
4000K: Comfortable, neutral white for long shifts
5000K: Crisp, high-contrast light for warehouses and sports
CRI ≥80 suits most industrial/commercial tasks; higher CRI optional on select models
- Controls and sensors
0–10V dimming enables scheduling and zoning
Motion (PIR/microwave) and daylight sensors reduce runtime substantially
- Power and environment
Verify voltage (100–277V; 347–480V on select models)
Choose IP65+ where dust, humidity, or light wash-downs are expected
- Mounting
Hook/chain/surface mount; always add a safety cable and proper grounding

UFO vs. Linear High Bay: Which should you pick?
- UFO High Bay (round)
Pros: Compact, rugged, fast to install; great for open areas and sports courts; easy maintenance
Best for: Open warehouse zones, production bays, gyms and arenas, exhibition spaces
- Linear High Bay (rectangular)
Pros: Rectangular distribution ideal for aisles and long, narrow spaces
Best for: Dense rack aisles, corridors, and highly regular floorplans
Many sites combine both: UFOs in open zones + linear high bays in aisles for optimal efficiency and uniformity.
Installation and maintenance tips
- De-energize circuits before work; follow local codes
- Use appropriate hooks/chain or surface brackets; add a safety cable
- If using 0–10V dimming or sensors, run control wiring as specified
- Commission sensors (sensitivity, hold time) before handover
- Periodically clean heat sinks and lenses; check gaskets in dusty or humid areas
- Match IP/IK ratings to the environment; verify ambient temperature limits
Frequently asked questions (FAQ)
Question：What ceiling height is best for UFO high bays?
Answer：They shine in 20–50 ft (6–15 m) ceilings; higher mounts may need narrower beams and higher outputs.
Question：How many fixtures do I need?
IAnswer：t depends on room size, target lux/foot-candles, reflectance, and optics. Share your floor plan and goals; LFD Lighting can recommend a count and layout.
Question：Can I dim them or add sensors?
Answer：Yes. Most models support 0–10V dimming; motion and daylight sensors are available on select models.
Question：Are they DLC/UL listed?
Answer：Select models carry DLC and UL listings. Check each product page for current certifications and rebate eligibility.
Question：Can I use them in damp or dusty spaces?
Answer：Choose IP65-rated models and follow installation guidance. Always confirm the environment and model specs.
Question：4000K vs. 5000K—what should I pick?
Answer：4000K is neutral and comfortable; 5000K is brighter and sharper for warehousing and sports.
Question：Can they replace metal halide one-for-one?
Answer：In many cases, yes—with lower wattage and better maintained light levels. Always verify with a photometric layout.
