REITA LED high bay lights are designed for warehouses, factories, workshops, logistics centers, distribution facilities, aircraft hangars, gymnasiums and other commercial or industrial buildings with high ceilings.
Our high bay lighting range includes compact UFO LED high bay lights, linear high bay fixtures and high-output industrial high bays. Available configurations cover multiple wattages, lumen packages, beam angles, input voltages, dimming systems and intelligent controls for both new construction and LED retrofit projects.
Choosing a high bay light should not start with wattage alone. Mounting height, required illuminance, fixture spacing, building geometry, rack layout, beam angle, voltage and operating environment all influence the final fixture selection.
If you have a high bay lighting project, send REITA the building dimensions, mounting height, voltage, target lux or foot-candles and existing fixture information. We can help select the appropriate fixture family and prepare a project-based lighting recommendation.

What Is a High Bay LED Light?
A high bay light is a luminaire designed to illuminate indoor spaces from relatively high mounting positions. High bay fixtures are commonly installed in buildings where conventional ceiling lights cannot efficiently deliver sufficient illumination to the floor or working plane.
Typical high bay applications include:
- Warehouses and distribution centers
- Manufacturing plants
- Production workshops
- Logistics facilities
- Aircraft hangars
- Large maintenance halls
- Supermarkets and wholesale facilities
- Exhibition halls
- Gymnasiums and indoor sports facilities
- High-ceiling commercial buildings
Modern LED high bay lights combine high lumen output with controlled optical distribution and substantially lower electrical power than many older HID, metal halide and fluorescent high bay systems.
For industrial environments where operating temperature, dust, moisture, vibration or other site conditions are important, see our detailed industrial high bay lighting fixture selection guide.
UFO High Bay Lights vs Linear High Bay Lights
UFO and linear fixtures are the two main high bay formats used in modern warehouse and industrial lighting projects.
UFO LED High Bay Lights
UFO high bay lights use a compact circular housing and normally provide symmetrical light distribution. They are widely used for open industrial and commercial areas because they provide high lumen output from a relatively compact fixture.
Typical applications include:
- Open warehouses
- Bulk storage areas
- Factories
- Assembly workshops
- Maintenance buildings
- Commercial high-ceiling spaces
- Gymnasiums
REITA offers multiple UFO high bay light series covering standard, power-selectable, intelligent-control and high-output applications.
Linear LED High Bay Lights
Linear high bays use an elongated housing and are often better suited to rectangular areas where light must follow aisles, production lines or storage racks.
Typical applications include:
- High-rack warehouses
- Narrow warehouse aisles
- Picking and packing areas
- Production lines
- Conveyor systems
- Long rectangular work areas
The correct decision should be based on room geometry and light distribution rather than fixture appearance alone.
For a more detailed comparison, read UFO vs Linear High Bay Lights for Warehouse Ceilings.
How to Choose LED High Bay Light Wattage
High bay wattage should be selected according to mounting height, fixture efficacy, beam angle, target illuminance, spacing and the physical layout of the building.
The following ranges can be used only as an initial project reference:
| Approximate Mounting Height | Typical LED High Bay Starting Range | Typical Application |
|---|---|---|
| 6–8 m / 20–26 ft | 80W–120W | Lower warehouse areas and workshops |
| 8–10 m / 26–33 ft | 100W–150W | General warehouses and factories |
| 10–12 m / 33–39 ft | 150W–200W | Medium-height industrial buildings |
| 12–15 m / 39–49 ft | 180W–240W | Large warehouses and manufacturing halls |
| 15–20 m / 49–66 ft | 240W–400W | High industrial halls and large facilities |
| Above 20 m / 66 ft | Project-specific high-output solution | Very high ceilings, hangars and heavy industrial halls |
These wattage ranges are not a substitute for a lighting calculation. A 150W high bay producing 30,000 lumens can perform very differently from a 150W fixture producing 20,000–22,000 lumens. Beam angle and fixture spacing can also change the resulting lux level substantially.
For warehouse-specific fixture quantity and layout planning, use our warehouse LED lighting calculator guide.
100W, 150W, 200W and Higher-Power High Bay Lights
Commercial high bay LED lights are available in many power levels. Instead of treating each wattage as a completely separate product category, REITA selects wattage according to the required lumen output and project conditions.
100W LED High Bay Lights
100W high bay lights are commonly considered for lower mounting heights, smaller warehouses, workshops, commercial storage areas and energy-efficient replacements where the existing lighting requirement is moderate.
150W LED High Bay Lights
150W LED high bay lights are among the most common configurations for general warehouse and factory applications. Depending on fixture efficiency, they can provide approximately 22,000–30,000 lumens and are suitable for many medium-height installations.
200W LED High Bay Lights
200W LED high bay lights are typically selected when higher mounting heights, wider fixture spacing or greater illumination levels require additional lumen output.
The HGB6 Series, for example, includes 200W configurations with different luminous efficacy options and several beam angles for project selection.
240W–300W LED High Bay Lights
Higher-output high bays may be suitable for larger industrial halls, taller warehouses and retrofit projects where fixture positions cannot easily be changed.
400W–600W High-Power LED High Bays
Very high-output high bays are specialized fixtures rather than standard replacements for every warehouse. REITA’s HBG1 high-power UFO high bay series is designed for high-ceiling and heavy-duty industrial applications requiring substantially higher lumen output.
High-Efficiency LED High Bay Lighting
Luminous efficacy describes how many lumens a fixture produces for each watt of electrical input and is normally expressed as lumens per watt (lm/W).
Higher efficacy can reduce required electrical power, but efficacy should never be evaluated alone. A professional high bay lighting project should also consider:
- Actual lumen output
- Beam distribution
- Driver reliability
- LED operating temperature
- Power factor
- Surge protection
- CRI and color temperature
- IP and IK ratings
- Dimming compatibility
- Expected operating hours
REITA HGB6 configurations are available with 150 lm/W, 170 lm/W and 200 lm/W efficiency options, allowing distributors and project buyers to balance project cost, lumen output and energy-efficiency requirements.
Choose the Correct Beam Angle for High Bay Lighting
A high-output fixture with the wrong beam angle can still produce an inefficient lighting system.
Wide beam angles distribute light across a larger area and are generally suitable for lower or medium mounting heights and open spaces. Narrower distributions concentrate more light toward the working plane and may be useful when fixtures are installed higher above the floor.
| Beam Angle | Typical Use |
|---|---|
| 60° | Higher mounting positions or areas requiring more concentrated downward illumination |
| 90° | General warehouse, industrial and commercial high bay lighting |
| 110°–120° | Open areas, lower mounting positions and wider fixture coverage |
The correct beam angle also depends on fixture spacing and room dimensions. Narrow beams installed too far apart can create bright spots and dark zones, while excessively wide beams at high mounting heights may reduce useful illuminance on the floor.
See our warehouse lighting layout, spacing and mounting height guide for a more detailed explanation.
High Bay Lighting Levels: Lux and Foot-Candles
Wattage and lumens describe the fixture. Lux and foot-candles describe how much light reaches the working surface.
This distinction is especially important in warehouses and factories because two buildings using the same high bay lights may require completely different fixture quantities.
Lighting requirements depend on:
- Type of work performed
- Storage configuration
- Aisle width
- Mounting height
- Floor and wall reflectance
- Required horizontal illumination
- Required vertical illumination
- Uniformity requirements
For practical warehouse illuminance recommendations and lux-to-foot-candle conversion, see our warehouse lighting levels guide.
Smart High Bay Lights with Motion Sensors and Dimming
High bay lights are often installed in facilities that operate for long hours, but many warehouse or storage zones are not continuously occupied. Intelligent lighting controls can reduce unnecessary operating hours while maintaining adequate illumination when workers enter the area.
Depending on the selected REITA series and configuration, control options may include:
- 0–10V dimming
- PIR motion sensors
- Microwave motion sensors
- Daylight sensors
- Zhaga interfaces
- Bluetooth control
- Zigbee control
- Tuya APP control
- Sensor-ready sockets
- Emergency backup options on selected models
The HGB6 UFO high bay series is particularly suitable for projects requiring sensor and smart-control flexibility.
Controls should be planned as part of the lighting system rather than added only after fixture installation. Sensor placement, detection zones, dimming levels and time delays should reflect the actual movement patterns inside the facility.
120–277V and 277–480V High Bay Lighting
Input voltage must be confirmed before selecting high bay fixtures.
Many commercial and industrial buildings in North America operate high bay lighting on 120–277V circuits, while larger industrial facilities may use 347V or 480V electrical systems.
Standard REITA high bay models are available with different voltage configurations depending on the series. For projects requiring high-voltage operation, the HBG1 Series can be configured for 277–480V applications.
Always provide the actual supply voltage and frequency when requesting a quotation. Voltage should not be assumed based only on the country or project type.
Commercial High Bay Lighting Applications
Warehouse High Bay Lights
Warehouses are one of the largest applications for LED high bay lights. Open storage areas often use UFO high bays, while high-rack aisles may require more controlled linear distributions.
For a complete warehouse fixture strategy, see Industrial Warehouse Lighting Fixtures: Layout, Mounting Height and Fixture Selection.
Factory High Bay Lighting
Factories require lighting that supports production, maintenance, inspection and safe movement. Fixture selection should consider mounting height, dust, moisture, ambient temperature and operating hours.
Read our industrial high bay lighting guide for factory-specific selection considerations.
Logistics and Distribution Centers
Distribution centers often include several different lighting zones, including open floors, tall rack aisles, sorting areas, packing stations and loading docks. One high bay fixture type may not be suitable for every zone.
Workshops and Maintenance Facilities
Workshops generally require comfortable, uniform illumination at the actual task plane. Lower mounting heights may allow wide-beam high bays, while inspection or detailed mechanical work can require higher illuminance levels.
Gym and Indoor Sports Facilities
LED high bays can be used in many school gyms and recreational sports halls, but sports lighting requires additional attention to glare, uniformity and upward viewing conditions.
See our dedicated high bay gym lighting guide before using a standard warehouse high bay in an indoor sports facility.
Aircraft Hangars and Large Indoor Halls
Large hangars and high industrial halls may require high-output fixtures, controlled optics and higher supply voltages. In these projects, photometric design is particularly important because large fixture spacing and high mounting positions amplify layout errors.
Replacing Metal Halide High Bay Lights with LED
Many warehouses and industrial buildings still operate 250W, 400W, 1000W or higher-power metal halide and HID high bay fixtures.
An LED retrofit should not use a simple one-to-one wattage rule.
Instead, compare:
- Existing fixture wattage
- Actual total system wattage including ballast losses
- Existing fixture lumen depreciation
- Required maintained illuminance
- Current fixture spacing
- Mounting height
- New LED fixture lumen output
- Beam distribution
- Operating hours
- Control requirements
A correctly designed LED high bay retrofit can substantially reduce connected load while improving usable illumination and reducing relamping requirements.
However, the final replacement ratio should be verified using the actual project layout instead of relying only on statements such as “150W LED replaces 400W metal halide.”
High Bay Lighting Layout and Photometric Design
Fixture selection is only one part of a high bay lighting project.
A professional layout should evaluate:
- Building length and width
- Mounting height
- Fixture quantity
- Fixture spacing
- Beam angle
- Target lux or foot-candles
- Uniformity
- Rack and machinery obstruction
- Reflective surfaces
- Emergency lighting requirements
- Sensor and control zones
For simple preliminary calculations, review our warehouse LED lighting calculator.
For projects requiring accurate fixture positioning and verification, REITA recommends using photometric files and lighting simulation rather than selecting lights only from a wattage chart.
How to Select the Right High Bay LED Light
When comparing high bay lighting fixtures, use the following sequence.
1. Confirm the Mounting Height
Mounting height determines the starting range for power, lumen output and optical distribution.
2. Define the Required Lighting Level
Determine the target lux or foot-candles according to the actual work being performed.
3. Review Building Geometry
Identify open areas, rack aisles, machinery, production lines and other physical obstructions.
4. Choose UFO or Linear High Bay
Select the fixture geometry according to the area being illuminated, not simply according to price or appearance.
5. Select Lumens Before Wattage
Compare actual lumen output and efficacy instead of assuming that all fixtures with the same wattage perform equally.
6. Select the Beam Distribution
Match the optical distribution to mounting height, spacing and target area.
7. Confirm Input Voltage
Specify 120V, 208V, 240V, 277V, 347V, 480V or other actual project voltage before ordering.
8. Define Controls
Determine whether the project requires 0–10V dimming, motion sensing, daylight harvesting or another control system.
9. Check Environmental Conditions
Temperature, dust, moisture, washdown requirements and other environmental factors can affect fixture selection.
10. Verify the Layout
For larger projects, use photometric simulation to confirm fixture quantity, spacing, illuminance and uniformity before installation.
High Bay Lights for Standard and Harsh Industrial Environments
Standard LED high bay lights are designed for normal warehouse and industrial ambient temperatures. They should not automatically be used in extreme-temperature areas simply because the fixture has a high IP rating or heavy aluminum housing.
Applications near furnaces, ovens, steel production equipment, boilers or other heat sources may require dedicated high-temperature luminaires.
If ambient temperature is unusually high, review REITA’s industrial light fixture selection guide before specifying a standard high bay.
