High bay light fixtures are generally used in spaces with ceiling heights of 20 feet or higher. The appropriate mounting height depends on fixture output, distribution, spacing, target light levels and the specific task being performed below the fixtures. 

Adjustable aircraft cable, chain, cord, stem and surface mounting options provide flexibility for broad, uniform coverage in high-ceiling applications. Review photometrics and layout conditions to select the appropriate fixtures.

UFO high bays are commonly used for broad, open-area illumination in warehouses, distribution centers and industrial facilities. Linear high bays can support aisle-based layouts and large rectangular spaces. Pendant-style high bays can provide high-output illumination while offering a more aesthetic form in commercial or architectural environments.

Required lumen output depends on:

• Mounting height
• Fixture spacing
• Ceiling and surface reflectance
• Beam distribution
• Target footcandles

Higher mounting heights and larger open areas typically require higher-output fixtures. High bay applications often require fixtures with outputs of 10,000 lumens or more. A photometric layout is the most reliable way to confirm output and uniformity for a specific project. You can request photometrics and a lighting layout for your space through our project services team.

Wattage-selectable high-bay lighting helps installers adjust light output in the field when final mounting height, layout conditions or target illumination levels differ from early project assumptions. It can also help accommodate spaces with varying ceiling heights, such as multi-purpose gyms and athletic facilities, while reducing the risk of overlighting or underlighting. The selected wattage should be verified against the lighting plan and applicable energy-code requirements.

Field-selectable color temperature allows the installer to select the white-light appearance that best fits the completed space. Cooler white light is often specified for task-oriented warehouse and industrial environments, while warmer options may be appropriate where visual character or occupant comfort is a greater consideration. This feature provides flexibility in selecting the final color temperature during installation or commissioning.

Common specifications include:

• 0-10V, ELV or TRIAC dimming 
• Occupancy and motion sensors
• Emergency battery backup

The appropriate control strategy depends on occupancy patterns, energy-code requirements and the need to maintain illumination during a loss of normal power.

Yes. Select sealed IP69K and NSF-rated fixtures are available for food and beverage processing environments with moisture, frequent washdown procedures and cleaning requirements. Confirm the fixture’s specific rating, mounting conditions and cleaning compatibility against project and facility requirements.

Yes. We produce several high bay lights right here in America. Select the filter options for Made in the USA or Buy American Act to view compliant fixtures.

Yes. High bay lighting is the ideal lighting solution for these applications. It can provide general, uniform illumination for gyms, courts and multi-purpose recreation spaces. Fixture and light-output selection should account for:

• Mounting height
• Light distribution
• Glare control
• Dimming
• Impact considerations
• Emergency lighting requirements

Yes. Our team can help architects, designers and contractors review fixture options, spec sheets, IES files, photometrics, code compliance and submittal requirements. For projects with BAA, Made in USA, wet-location, IP69K, NSF, controls or emergency-backup requirements, we can help identify appropriate products and documentation.
