High bay LED lights are overhead fixtures built for large indoor areas with ceilings typically 20 feet or higher, such as warehouses, manufacturing plants, distribution centers, and gymnasiums. This category includes both UFO-style high bays, which feature a compact circular form suited for open floor layouts, and linear high bays, which offer a rectangular profile ideal for aisles, racking systems, and production lines. Fixtures are commonly mounted directly above open floors, along rows of shelving, or suspended over work zones in facilities with expansive layouts.

These products are a core part of Commercial & Industrial Lighting Solutions, with physical placement in environments like aircraft hangars, service bays, big box retail stores, and indoor sports courts. High bay LED lights are frequently installed in spaces where consistent overhead illumination is needed across broad areas or between tall storage racks, supporting layouts found in logistics hubs, assembly areas, and large-scale indoor venues.

What Are LED High Bay Lights

Commercial LED high bay lighting fixtures are designed for large indoor spaces with ceilings typically 20 feet or higher. They deliver high lumen output with engineered optics to provide bright, even illumination in warehouses, factories, gyms, aircraft hangars, and distribution centers. High bay lights are the most common LED commercial lights for indoor applications.

LED Lighting Supply Commercial and Industrial LED High Bays

Facility upgrades from metal halide and fluorescent systems demand precise matching of ceiling height, lumen requirements, and beam patterns to avoid costly mistakes. Drawing from 15+ years of lighting experience in industrial and commercial settings, LED Lighting Supply's Product Specialists have developed proven methodologies that eliminate guesswork and deliver optimal performance for each unique application. The U.S. Department of Energy reports that LED technology can reduce energy consumption by 75% compared to traditional lighting in commercial and industrial applications. Their research shows that proper LED high bay selection and installation techniques are critical factors in achieving maximum energy savings and operational efficiency in large indoor spaces.

Warehouse LED Lighting

Large Indoor Spaces-Warehouses & Distribution Centers. The customer selected our 300 Watt UFO Warehouse Light | 45,000 Lumens to achieve the required foot candle levels with balanced lighting distribution across the entire floor

Need help choosing Read our Buyers Guide to LED High Bays (foot-candle targets, lumen planning, optics, and fixture selection).

Quick Selection Guide

  • Fixture type: Use UFO high bays for open areas and HID replacement; use linear high bays for aisles, racking, and fluorescent replacement
  • Ceiling height match: Verify lumen output and beam angle match your mounting height (general guidance: 120 deg for under 25 ft, 90 deg for 25-35 ft, 60 deg for 35+ ft)
  • Foot-candle targets: Start with 20-30 fc for warehouse storage, 30-50 fc for aisles/distribution, 50-80 fc for manufacturing - confirm with photometric plan
  • Voltage compatibility: Verify building electrical service (120-277V or 277-480V) and select a matching driver or universal option
  • Environmental ratings: Check datasheet for IP/IK ratings, temperature range, and certifications required for your application
  • Controls integration: Consider 0-10V dimming with motion sensors for additional energy savings in task-based zones, depending on occupancy patterns, control settings, and facility usage

Tip: Improper fixture spacing leads to uneven distribution - plan spacing at roughly 1.2 to 1.5 times mounting height, then verify with photometric layout for larger projects.

LED Lighting Supply High Bay Product Selector

Use this selector to identify the best starting high bay recommendation based on mounting height, application type, and lighting requirements.

Note: Selector results are general planning guidance. Final fixture count, spacing, beam angle, and electrical compatibility should be verified with a photometric plan and a qualified professional when required.

LED High Bay Fixture Types

LED high bay lights are available in different fixture styles and replacement packages depending on ceiling height, existing fixture type, lumen requirements, light distribution, and facility layout. The correct option should be selected based on mounting height, target foot-candles, voltage, optics, controls, and environmental conditions.

Fixture Type Common Applications
LED UFO High Bay Lights Used in open warehouses, manufacturing plants, distribution centers, gymnasiums, aircraft hangars, and other large indoor spaces where compact, high-output fixtures are needed for strong downward illumination and HID replacement.
LED Linear High Bay Lights Used in aisles, racking layouts, production lines, assembly areas, retail back-of-house spaces, and fluorescent replacement projects where long, even light distribution is preferred.
400W Metal Halide High Bay LED Replacement Used to replace traditional 400 watt metal halide or HID high bay fixtures in warehouses, shops, factories, and general industrial spaces. Final wattage and lumen output should be confirmed based on mounting height and target foot-candle levels.
1000W Metal Halide High Bay LED Replacement Used for higher-output HID replacement projects in tall warehouses, aircraft hangars, manufacturing areas, sports facilities, and large indoor workspaces where high lumen output is required.
6 Lamp T5 High Bay LED Replacement Used to replace fluorescent 6-lamp T5 high bay fixtures in warehouses, production areas, retail storage spaces, and other commercial interiors where linear distribution and reduced maintenance are desired.
Indirect LED High Bay Lights Used in gymnasiums, indoor courts, field houses, and sports facilities where indirect or softer light distribution can help reduce glare while supporting even illumination for athletic activity.

High Bay Lighting Comparisons

High bay lights are often compared with other industrial and commercial lighting options. The right choice depends on ceiling height, fixture layout, light distribution, mounting conditions, environmental exposure, and whether the space requires general illumination, aisle lighting, washdown protection, or a retrofit for older HID fixtures.

LED High Bay vs Metal Halide High Bay

LED high bay lights are commonly used to replace metal halide high bay fixtures in warehouses, gyms, manufacturing plants, aircraft hangars, and large commercial facilities. Compared with metal halide, LED high bays use less energy, turn on instantly, maintain light output more consistently, and reduce maintenance because there are no lamps or ballasts to replace.

Metal halide fixtures can produce strong light when new, but they lose output over time, require warm-up and restrike periods, and often consume additional energy through ballast draw. For many retrofit projects, LED high bays can reduce lighting energy use while improving visibility and fixture control options.

Comparison What to Know
LED High Bay Energy efficient, instant-on, long-life, dimmable options, compatible with sensors and lighting controls, and lower maintenance than HID fixtures.
Metal Halide High Bay Older HID technology with warm-up time, lumen depreciation, ballast maintenance, higher energy use, and more frequent lamp replacement.

UFO vs Linear High Bay Lights

UFO and linear high bay lights are both used for high-ceiling commercial and industrial spaces, but they distribute light differently and are often selected for different layouts.

UFO high bay lights are compact round fixtures commonly used in open areas, manufacturing spaces, gymnasiums, auto shops, and warehouses where broad, general illumination is needed. They are often easy to install as one-for-one replacements for round HID high bays.

Linear high bay lights are rectangular fixtures commonly used over aisles, racking, production lines, retail warehouse spaces, and areas where a longer light distribution pattern is helpful. They can provide more directional coverage along rows or rectangular work areas.

Fixture Type Best Used For
UFO High Bay Open spaces, higher ceilings, general area lighting, gyms, manufacturing plants, and round HID high bay replacements.
Linear High Bay Warehouse aisles, racking, production lines, rectangular layouts, retail warehouse spaces, and areas needing longer light distribution.

LED

High Bay vs Low Bay Lighting

The main difference between high bay and low bay lighting is mounting height. High bay fixtures are designed for higher ceilings where more lumen output and controlled light distribution are needed to deliver usable light to the floor or work surface. Low bay fixtures are used in lower-ceiling spaces where a high-output fixture may create glare, over-lighting, or poor visual comfort.

As a general planning guideline, high bay lights are commonly used in spaces with ceilings around 20 feet and higher, while low bay fixtures are commonly used below that range. The correct choice depends on mounting height, beam angle, lumen output, spacing, ceiling reflectance, and target foot-candle levels.

Lighting Type Typical Use
High Bay Lighting Higher-ceiling warehouses, manufacturing plants, gyms, aircraft hangars, distribution centers, and large industrial spaces.
Low Bay Lighting Lower-ceiling commercial, workshop, retail, storage, and industrial areas where lower mounting heights require less aggressive light distribution.

High Bay vs Vapor Tight Fixtures

High bay lights and vapor tight fixtures solve different lighting problems. A high bay fixture is selected primarily for mounting height, lumen output, and light distribution. A vapor tight fixture is selected for environmental protection against moisture, dust, dirt, and contaminants.

In dry warehouses, gyms, and manufacturing areas, a standard LED high bay may be the best choice. In wet, dusty, washdown, or corrosive environments, vapor tight fixtures may be required. Some facilities may need both characteristics, such as a high-output vapor tight fixture for a high-ceiling washdown or food-processing area.

Fixture Type Best Used For
High Bay Light High-ceiling spaces where lumen output, beam angle, spacing, and fixture layout are the main selection factors.
Vapor Tight Fixture Wet, dusty, dirty, or washdown environments where sealed construction and environmental protection are required.

Not sure which high bay fixture is right for your facility LED Lighting Supply can help review your ceiling height, fixture spacing, application, voltage, mounting conditions, target light levels, and environmental requirements to recommend the best high bay or industrial lighting option.

Recommended Foot-Candle Levels and Lighting Requirements by High Bay Application

Use these general planning ranges to estimate target light levels by application. Final fixture selection and layout should be verified with a photometric plan, especially for safety- or code-critical areas.

Most Common High Bay LED Lighting Applications

High bay lights are most commonly used in large indoor spaces with high ceilings, open layouts, and demanding visibility requirements. For warehouse projects, see our full warehouse lighting solutions page for application-specific design guidance.

Common Mistakes and How to Avoid Them

After many years of high bay installations across commercial and industrial facilities, these are the issues that most frequently impact lighting performance, project cost, and long-term reliability.

  • Using lumen packages that do not match the mounting height results in insufficient light levels. Use the Ceiling Height Match guidelines in the Quick Selection Guide as a starting point, then verify with photometrics for larger projects, racking, or safety-critical areas.
  • Specifying non-DLC-qualified fixtures in projects where rebates are expected. Some utility rebate programs require DLC qualification (often DLC Premium, but requirements vary by program). Always verify the rebate rules and match the fixture's DLC listing to your application.
  • Overlooking the need for emergency battery backup units along egress paths. Some facilities require emergency illumination along egress paths for code compliance. Confirm requirements with your licensed professional and local authority.
  • Installing motion sensors without adjusting the timeout values to the application. Set occupancy sensor timeouts to match the space. As a starting point, production zones often employ longer delays than storage areas, which are then adjusted during commissioning based on traffic patterns and safety needs.
  • Ignoring ambient temperature requirements when selecting fixtures for unconditioned or high-heat spaces. Always check operating temperature ratings, especially for warehouses, foundries, and cold storage facilities.
