Explore Bell LED high bay and low bay lights for warehouses, workshops, production areas and other large commercial or industrial spaces. Designed for installations with higher ceilings, the range offers powerful, energy-efficient illumination across wide working areas. Choose from different wattages, lumen outputs, beam angles and selected sensor or emergency options. Consider the mounting height, room dimensions and required light level when choosing the right Bell bay light for your application.
Bay lighting is designed for warehouses, production areas, workshops, sports halls and other large spaces with substantial ceiling heights. The correct fitting depends on mounting height, floor layout, required illumination, beam distribution and the conditions within the building.
Mounting Height
High Bay or Low Bay?
High bay generally describes lighting for higher mounting positions, while low bay refers to lower industrial or commercial ceilings. The decision should be based on calculations rather than height alone.
Light Distribution
Choose the Beam Angle
Narrower beams concentrate light from greater heights, while wider distributions can provide broader coverage at lower mounting heights or across open areas.
Control and Efficiency
Light Only When Needed
Sensors and dimming controls can reduce unnecessary operating hours in aisles, storage areas and intermittently occupied industrial spaces.
High Bay vs Low Bay
What Is the Difference?
High Bay Lighting
For Higher Mounting Positions
High bay fittings are designed to deliver useful illumination from elevated positions. They commonly use high lumen outputs and controlled optics to direct light towards the working plane.
Warehouses and distribution centres
Production and manufacturing areas
Aircraft hangars and large workshops
Sports and large assembly halls
Low Bay Lighting
For Lower Industrial Ceilings
Low bay applications generally use lower outputs or wider light distributions to provide even illumination without excessive intensity or glare at lower mounting positions.
Smaller workshops and storage areas
Loading and service areas
Retail warehouses
Lower-ceiling industrial units
There is no single mounting height that automatically determines whether a project needs a high bay or low bay. Ceiling height, spacing, optics, obstructions and required light levels should be assessed together.
Selection Checklist
What to Check Before Buying Bay Lighting
Specification
Why it matters
What to consider
Lumen output
Determines the quantity of visible light
Mounting height, working plane and target illumination
Beam angle
Controls the spread and concentration of light
Open areas, narrow aisles, racking and fitting spacing
IP rating
Shows protection against objects and moisture
Dust, damp, cleaning processes and environmental exposure
IK rating
Shows resistance to mechanical impact
Sports, industrial and exposed working environments
Control option
Determines sensor and dimming compatibility
1–10V, DALI, corridor dimming or plug-in sensors
Emergency compatibility
Provides supported backup-lighting options
Project design, compatible pack and emergency output
Compare high bays by lumens and light distribution rather than wattage alone. Two fittings with similar wattages may produce different outputs or illuminate the floor in different ways.
Fitting Format
Circular or Linear LED High Bays?
Circular High Bay
Compact, High-Output Format
Circular or UFO-style high bays provide powerful illumination from a compact fitting and suit many open industrial spaces.
Compact suspended profile
Useful across open floor areas
Multiple output and control options
Check compatible brackets and accessories
Linear High Bay
Designed for Aisles and Open Areas
Linear high bays distribute light across a longer fitting and can suit racking aisles, sports spaces and rectangular working areas.
High-area and low-area optics available
Useful above aisles and production lines
Can help align light with room geometry
Consider fitting orientation carefully
Optical Performance
Choosing the Beam Angle
Narrower Distribution
More Concentrated Light
A narrower beam can direct more light towards the floor from a higher position or provide controlled illumination into aisles.
Around 90°
Controlled Area Coverage
A medium distribution can balance downward intensity with useful coverage in higher or more structured industrial spaces.
Around 120°
Broad Light Distribution
A wider beam can provide broader coverage for lower mounting positions and open areas, subject to spacing and glare assessment.
Beam angle should not be selected in isolation. A lighting calculation should consider lumens, mounting height, spacing, room reflectance, racking and the required uniformity.
Environment and Durability
IP and IK Ratings for Industrial Spaces
IP Protection
Dust and Moisture Resistance
Bell high bays include different IP ratings, from models intended for suitable dry interiors to IP65 and IP66 options for more demanding environments.
IK Protection
Mechanical Impact Resistance
IK-rated models can provide additional resistance where fittings may be exposed to accidental impact, industrial activity or sports equipment.
Check ambient temperature, dust, moisture, chemicals, cleaning methods and heat sources as well as the IP and IK ratings. Product suitability depends on the complete environment.
Controls and Energy Management
Switchable Output, Sensors and Dimming
Wattage Switchable
Set the Required Output
Selected Illumina fittings provide multiple wattage settings, allowing one product to be configured for different mounting heights and lighting requirements.
Sensor Control
Respond to Occupancy
Compatible sensors can reduce output or switch lighting when an area is unoccupied, helping reduce unnecessary energy use.
Dimming Protocols
Integrate with Controls
Selected models support 1–10V, corridor dimming or DALI control. Match the fitting and driver to the building’s control system.
Confirm compatibility before combining a high bay with plug-in sensors, emergency packs or control accessories. Products within the same wider family may use different components.
Project Support
Planning a High Bay or Low Bay Installation?
Provide the building dimensions, mounting height, layout and required controls when asking for assistance. Racking plans and details of the activities performed in the space can also affect product selection.
For lower industrial ceilings and linear replacement projects, you can also compare the Bell LED batten collection .
What is the difference between a high bay and a low bay light?
High bay lighting is designed for higher mounting positions and commonly uses greater output or more controlled optics. Low bay lighting is intended for lower industrial ceilings, often using wider distribution or lower output to control glare and provide even coverage.
How many LED high bays do I need?
The quantity depends on the building dimensions, mounting height, fitting output, beam distribution, spacing, surface reflectance and required illumination. A lighting calculation is recommended rather than using floor area alone.
Should I choose a circular or linear high bay?
Circular high bays are compact and work well across many open areas. Linear high bays can suit aisles, production lines, rectangular spaces and applications requiring more directional distribution.
Which beam angle is best for a high bay?
Narrower beams concentrate light from greater heights, while wider beams provide broader coverage at lower heights or across open areas. The correct beam should be confirmed through the complete lighting layout.
Can Bell high bays be controlled by sensors?
Selected Bell Illumina high bays include or support compatible sensors. Check the exact fitting, sensor receptacle, detection requirements and control settings before ordering.
Are emergency options available for Bell LED high bays?
Compatible emergency packs are available for selected Bell high bay ranges. Confirm the fitting compatibility, emergency output, duration and project requirements before specifying a pack.
