LED High Bay Lights
LED high bays for 15–40 ft mounting heights—UFO and linear fixtures specified by optics, spacing criteria, and delivered lumens.
High bay LED fixtures are overhead luminaires specified for facilities with elevated mounting heights, typically 20 feet and above. Available in linear and round configurations, these fixtures are commonly deployed in modernization projects replacing legacy HID and fluorescent systems to support uniform illumination and stable electrical performance across large interior volumes. For planning variables such as mounting height relationships, lumen targets, beam angles, and fixture layout, consult the high bay lighting buying guide to assist with specification development.
This collection includes luminaires evaluated based on photometric distribution, mounting height, driver characteristics, thermal performance, and dimming capability to assist designers and facility teams in establishing controlled lighting conditions within warehouses, manufacturing environments, athletic facilities, and similar large-format spaces.

Technical FAQs for Commercial LED High Bay Lights
Engineering reference: See our high bay lighting buying guide for mounting height strategy, lumen calculations, beam angle selection, and layout methodology used in large-volume commercial and industrial facilities.
What are LED high bay lights designed for?
LED high bay luminaires are engineered for facilities with elevated mounting heights, commonly including warehouses, manufacturing plants, gymnasiums, logistics centers, and large retail environments. Their optical design supports concentrated light delivery from higher ceilings while maintaining target illuminance at the workplane.
At what ceiling height should high bay fixtures be considered?
High bay luminaires are typically evaluated when mounting heights exceed the effective range of standard ceiling fixtures. As ceiling height increases, higher lumen packages and controlled beam distributions are often required to maintain uniform illumination. See the high bay lighting buying guide for mounting guidance.
How should lumen output be selected for high bay installations?
Lumen selection should be based on required foot-candle levels rather than replacing legacy wattage. Mounting height, aisle configuration, surface reflectance, and beam angle all influence delivered illuminance. Photometric modeling is recommended to verify layout performance before specification.
How does beam angle affect high bay lighting performance?
Narrow beam distributions concentrate light for higher mounting positions or defined aisle layouts, while wider beams support broader coverage at moderate heights. Improper beam selection can produce hot spots or insufficient light between fixtures. Beam strategy should always be validated through photometric analysis using the high bay lighting buying guide.
When should linear high bays be used instead of round fixtures?
Linear high bays are often selected for aisle-based layouts where elongated distribution aligns with rack configurations. Round luminaires may be preferred for open floor plates that benefit from symmetrical coverage. Fixture geometry should reflect the physical layout of the space.
How should fixture spacing be determined in high ceiling environments?
Spacing is influenced by lumen package, beam distribution, and mounting height. Excessive spacing can create dim zones, while overly tight spacing may increase energy use without improving task visibility. IES-based calculations help establish spacing criteria that support uniform coverage.
What correlated color temperature is commonly specified for high bay lighting?
Many industrial and large-volume commercial facilities specify neutral to higher color temperatures to support visual contrast and task recognition. Maintaining consistency across fixture families helps prevent visible variation throughout the facility.
How important is glare control in high bay applications?
Although fixtures are mounted above typical sightlines, excessive brightness can still affect operators of forklifts, machinery, or elevated platforms. Optical control and appropriate lumen selection help support visual comfort while maintaining safe visibility.
What electrical characteristics should be reviewed before specifying high bay fixtures?
Confirm input voltage range, driver compatibility, circuit capacity, and inrush current relative to breaker ratings. Large deployments should evaluate electrical infrastructure to support simultaneous startup conditions.
Do LED high bay lights typically support dimming or advanced controls?
Many drivers are compatible with dimming systems, occupancy sensors, and daylight-responsive controls used to satisfy energy codes and operational strategies. Verify control compatibility and commissioning requirements prior to specification. Planning considerations are outlined in the high bay lighting buying guide.
When are emergency lighting provisions required in high bay facilities?
Certain occupied areas and egress pathways may require illumination during power interruption. This is commonly achieved using LED emergency backup drivers or dedicated emergency luminaires. Requirements are typically governed by building and life-safety codes. See the exit and emergency lighting buying guide for regulatory context.
Are high bay fixtures suitable for environments with dust or moisture?
Environmental suitability depends on the fixture listing and enclosure design. Facilities exposed to airborne particulates, humidity, or washdown procedures may require sealed construction. When those conditions exist, evaluate LED vapor-tight lights designed for environmental protection.
How does reflectance influence lighting performance in large facilities?
Ceiling, wall, and floor reflectance can significantly affect perceived brightness and uniformity. Higher reflectance surfaces help redistribute light more effectively, while darker finishes absorb light and may require higher delivered lumens to maintain target illuminance.
What factors influence long-term serviceability of high bay lighting systems?
Evaluate driver accessibility, mounting hardware, thermal design, component replaceability, and warranty terms before standardizing a fixture family. Consistent configurations across a facility can simplify maintenance planning and reduce operational disruption.
When should standard ceiling fixtures be avoided in high mounting applications?
Fixtures designed for lower ceilings often lack the optical control required to deliver sufficient light from elevated positions. In those cases, purpose-built high bay luminaires are typically more appropriate than general ceiling fixtures such as LED strip lights or LED wraparound lights.
