REITA high bay emergency lighting combines normal high-output LED high bay illumination with an emergency battery backup system designed to provide temporary lighting when normal mains power is interrupted.
These systems are suitable for warehouses, factories, industrial halls, logistics centers, workshops, production areas and other high-ceiling facilities where part of the lighting system needs to remain operational during a power failure.
REITA provides both UFO high bay emergency lighting and linear high bay emergency lighting, allowing project buyers to select the fixture type according to mounting height, building layout, required light distribution and emergency lighting strategy.
Emergency high bay lighting should not be selected only by normal fixture wattage. A complete project should also define emergency output, required backup duration, battery configuration, input voltage, charging system, testing requirements and the location of fixtures that must remain illuminated during a power failure.

What Is High Bay Emergency Lighting?
High bay emergency lighting is a lighting system designed for high-ceiling spaces where selected high bay fixtures continue to provide reduced emergency illumination after the normal electrical supply fails.
During normal operation, the fixture functions as a standard LED high bay.
When mains power is available:
- The normal LED driver operates the high bay.
- The emergency system remains in standby.
- The emergency battery is maintained or charged according to the system design.
When mains power fails:
- The emergency system detects the loss of normal power.
- The battery-powered emergency driver activates.
- The LED module continues operating at a reduced emergency output.
- The fixture provides temporary illumination for the designed backup period.
The fixture normally does not continue operating at its full 100W, 150W, 200W or 300W normal power during emergency operation. Emergency mode typically uses a separate reduced output selected according to the project requirements.
Why High Bay Emergency Lighting Is Different from Standard Emergency Lights
Traditional emergency lighting often uses small dedicated luminaires installed along escape routes, corridors and exits.
High bay industrial facilities create a different challenge.
Warehouses and factories can have:
- High mounting positions
- Large open floor areas
- Tall storage racks
- Heavy machinery
- Forklift traffic
- Large distances between lighting points
In these spaces, selected high bay fixtures can be equipped with emergency backup so that existing high-level lighting positions contribute to emergency visibility during a power failure.
The emergency system should still be designed according to the actual facility and applicable project requirements rather than simply adding a battery to every high bay.
UFO High Bay Lights with Emergency Battery Backup
UFO high bay lights are widely used in open warehouses, factories and industrial buildings because their round optical design provides high lumen output from a compact fixture.
For projects requiring emergency operation, selected UFO high bays can be configured with an emergency backup system.
The REITA HBG2 UFO LED High Bay is available from 100W to 300W and can be supplied with an emergency backup option for project-specific requirements.
This makes it suitable for applications such as:
- Open warehouse floors
- Factories
- Industrial workshops
- Logistics centers
- Distribution facilities
- Commercial storage buildings
- Industrial halls
During normal operation, the fixture provides the required high bay illumination. During a power interruption, the emergency system provides reduced temporary illumination according to the selected emergency configuration.
Linear High Bay Lights with Emergency Battery Backup
Linear high bays are particularly useful where the shape of the illuminated area is rectangular or where more uniform longitudinal light distribution is required.
The REITA HL1 Emergency Linear LED High Bay is available in 120W, 150W and 200W configurations and is specifically designed to support emergency battery backup projects.
Typical applications include:
- Warehouse aisles
- Production lines
- Assembly areas
- Industrial halls
- Workshops
- Logistics facilities
- Service and maintenance areas
The linear form factor can also provide more uniform illumination across long work areas compared with a single round point-source fixture.
UFO vs Linear Emergency High Bay: Which Should You Use?
| Application | Recommended Starting Point |
|---|---|
| Open warehouse floor | UFO Emergency High Bay |
| Open factory hall | UFO or Linear depending on layout |
| Long warehouse aisle | Linear Emergency High Bay |
| Production line | Linear Emergency High Bay |
| Large open industrial area | UFO Emergency High Bay |
| Rectangular work zone | Linear High Bay may provide better distribution |
The correct choice should be based on photometric distribution and building layout rather than fixture shape alone.
For a broader comparison of high bay formats, see UFO vs Linear High Bay Lights.
How Does an Emergency High Bay Battery Backup System Work?
A typical emergency high bay system contains several functional components:
- Normal LED driver
- LED module
- Emergency driver or emergency control module
- Rechargeable battery
- Charging circuit
- Power-failure detection
- Test and status components where required
During normal operation, mains electricity powers the LED high bay and maintains the emergency battery system.
If the normal electrical supply fails, the emergency system automatically transfers the LED load to battery-supported emergency operation.
Because battery capacity is limited, the emergency driver normally operates the LED module at a much lower power level than during standard high bay operation.
Normal Wattage vs Emergency Wattage
This is one of the most important concepts when specifying high bay emergency lighting.
For example, a fixture may operate normally at:
- 100W
- 120W
- 150W
- 200W
- 250W
- 300W
But during emergency operation, the emergency driver may operate only part of the LED system at a reduced power level.
The emergency wattage should therefore be specified separately from the normal fixture wattage.
| Specification | Meaning |
|---|---|
| Normal Fixture Wattage | Power used during standard mains-powered operation |
| Emergency Wattage | Reduced power supplied by the emergency system after mains failure |
| Emergency Lumens | Light output produced during emergency operation |
| Emergency Runtime | Length of time emergency illumination is maintained |
A buyer should therefore never assume that a “150W high bay with battery backup” provides 150W of emergency output.
Emergency Lumens Matter More Than Battery Wattage Alone
The objective of an emergency lighting system is to provide the required illumination during a power failure.
This means emergency lumen output is often more useful than looking only at emergency driver wattage.
Emergency output depends on:
- Emergency driver power
- LED module efficiency
- Battery condition
- Driver efficiency
- Fixture optical distribution
- Mounting height
A high bay installed 12 meters above the floor requires a different emergency-lighting evaluation from the same fixture installed at 6 meters.
Emergency Runtime
Emergency runtime describes how long the fixture can continue providing emergency illumination after mains power fails.
The required duration depends on the project specification and applicable regulatory requirements.
Possible project specifications may require:
- 90-minute emergency operation
- Longer backup periods
- Project-specific runtime
REITA can configure selected emergency high bay solutions according to the required runtime and battery capacity, subject to the fixture, emergency driver and project design.
The exact emergency duration should be confirmed before production rather than assumed from the normal high bay model number.
Integrated vs External Emergency Battery Backup
Emergency high bay systems can use different physical battery configurations.
Integrated Emergency System
The emergency components are incorporated into or closely attached to the luminaire assembly.
Potential advantages include:
- Compact installation
- Fewer separate components
- Cleaner fixture appearance
However, available internal space, battery size and thermal environment can limit some configurations.
External Emergency Battery Box
An external battery or emergency power box can be mounted separately from the main luminaire.
This approach can provide more flexibility for:
- Larger battery capacity
- Different emergency output requirements
- Maintenance access
- Thermal separation
- Customized industrial projects
The REITA HL1 platform can support project-based integrated or external emergency solutions depending on the required configuration.
How to Choose an Emergency Battery for a High Bay Light
Battery selection should be based on the complete emergency operating requirement rather than physical battery size alone.
Important factors include:
- Required emergency wattage
- Required emergency lumens
- Required runtime
- Battery voltage
- Battery capacity
- Charging requirements
- Ambient temperature
- Expected maintenance schedule
- Emergency driver compatibility
Increasing emergency output normally increases the required battery energy capacity if the same runtime must be maintained.
Emergency Driver vs Normal LED Driver
A standard LED driver and an emergency LED driver perform different functions.
| Component | Main Function |
|---|---|
| Normal LED Driver | Operates the high bay from normal AC mains power |
| Emergency Driver | Provides controlled LED power from the emergency battery after mains failure |
| Battery | Stores electrical energy for emergency operation |
| Charging / Transfer System | Maintains battery charge and changes operating mode during power failure |
The emergency driver must be compatible with the LED module and battery system.
For a deeper technical explanation, see our upcoming guide to LED emergency drivers for high bay lighting.
Emergency High Bay Lights for Warehouses
Warehouses are one of the main applications for high bay emergency lighting.
A warehouse emergency-lighting strategy may need to consider:
- Rack aisles
- Open storage zones
- Picking areas
- Packing stations
- Forklift routes
- Loading and staging areas
- Exit access routes
It is generally unnecessary to equip every high bay fixture with battery backup.
Instead, emergency fixtures should be positioned according to the required emergency-lighting design.
For the normal warehouse lighting system, see our warehouse lighting fixture guide.
Emergency High Bay Lighting for Factories
Factories can have more complex emergency-lighting requirements because workers may be located around machinery, production lines, elevated platforms and process equipment.
Important considerations include:
- Critical work areas
- Safe movement after power loss
- Exit access
- Machinery shutdown procedures
- Emergency work zones
- Mounting height
- Industrial environmental conditions
A standard warehouse emergency high bay should not automatically be used in high-temperature or hazardous industrial areas without verifying the fixture’s environmental suitability.
Emergency Lighting for High Rack Aisles
High-rack warehouses require special attention because racks can block lateral light distribution.
A fixture that provides acceptable emergency illumination in an open warehouse may not produce the same result inside a narrow aisle.
Linear high bays or aisle-oriented distributions can sometimes provide better coverage for these areas.
Fixture placement should therefore be evaluated using the actual rack geometry.
Emergency High Bay Lighting and Mounting Height
Mounting height is especially important during emergency operation because emergency output is much lower than normal high bay output.
A fixture that produces adequate emergency illumination from 6 meters may not produce the same floor-level illumination when installed at 12 or 15 meters.
Emergency lighting design should therefore consider:
- Emergency lumen output
- Mounting height
- Beam angle
- Fixture spacing
- Required emergency illuminance
For normal high bay layout principles, see our high bay mounting height and spacing guide.
Emergency High Bay Lighting with Dimming and Sensors
Modern high bay projects may combine several functions in one lighting system:
- Normal LED high bay operation
- 0–10V or 1–10V dimming
- Motion sensing
- Daylight sensing
- Emergency battery backup
These functions must be coordinated correctly.
The emergency system must still provide the intended emergency output when normal lighting controls, sensors or building automation lose mains power.
For normal high bay control strategies, see our high bay motion sensor and dimming guide.
What Happens When the Power Fails?
A properly configured emergency high bay system automatically detects failure of the normal lighting supply.
The emergency system then:
- Detects loss of mains power.
- Activates battery-supported emergency operation.
- Supplies reduced power to the LED module.
- Maintains emergency illumination for the specified period.
- Returns to normal operation and charging mode after mains power is restored.
The exact transfer method and operating logic depend on the emergency driver and battery configuration.
Testing and Maintenance
An emergency high bay is a safety-related lighting system, so battery backup should not simply be installed and ignored.
A maintenance program may include checking:
- Battery condition
- Charging status
- Emergency transfer operation
- Emergency runtime
- Status indicator
- Test function
- LED operation during emergency mode
- Physical condition of external battery boxes
Testing frequency and procedures should follow the requirements applicable to the project location and the emergency system being used.
Emergency High Bay Lighting Requirements
Emergency-lighting requirements vary by country, jurisdiction, building type and project specification.
A professional project may need to consider:
- Required emergency duration
- Required illumination level
- Emergency fixture locations
- Escape routes
- Testing requirements
- Battery and emergency equipment certification
- Local electrical and building codes
REITA should be provided with the project’s required standard or certification before the emergency high bay configuration is finalized.
Do not assume that one emergency battery configuration automatically satisfies every market or building code.
How Many Emergency High Bay Lights Are Needed?
The required quantity is not simply a percentage of the normal high bay fixture count.
For example, a warehouse with 100 normal high bay fixtures does not automatically require 10 or 20 emergency fixtures.
The correct quantity depends on:
- Emergency lighting layout
- Building geometry
- Mounting height
- Emergency lumen output
- Rack layout
- Required illumination
- Escape and circulation routes
Photometric verification is recommended for larger commercial and industrial projects.
