How to Select an Appropriate LED Emergency Driver?

Jul. 20, 2023

Selecting an appropriate LED emergency driver is crucial for ensuring the proper functioning of emergency lighting systems during power outages or emergencies. LED emergency drivers are designed to power LED luminaires at reduced output levels during emergency situations. When choosing the right LED emergency driver, several important factors should be considered to ensure compatibility, reliability, and compliance with safety regulations. Here's a step-by-step guide to help you select an appropriate LED emergency driver:


1. Determine the LED Luminaire Specifications:

Before selecting an emergency driver, gather information about the LED luminaire that needs to be powered during emergencies. Key specifications to be considered include:


- Input Voltage: Check the input voltage requirements of the LED luminaire. Most LED emergency drivers are designed to work with a range of input voltages, such as 120V or 277V AC.


- Output Power: Determine the power requirements of the LED luminaire in watts. The emergency driver's output power should be sufficient to meet or exceed the power demand of the luminaire.


- Output Current: LED emergency drivers provide a specific output current, typically measured in milliamps (mA). Ensure that the driver's output current matches the LED luminaire's current requirements.


- Dimming Compatibility: If the LED luminaire is dimmable, verify that the selected emergency driver is compatible with dimming functionality, as not all emergency drivers support dimmable luminaires.

2. Consider the Battery Type and Capacity:

LED emergency drivers are equipped with rechargeable batteries that provide power during emergencies. There are two main types of batteries used in LED emergency drivers:


- Nickel-Cadmium (Ni-Cd) Batteries: These batteries are cost-effective and widely used in emergency lighting. They offer good performance and reliability but have a lower energy density compared to other battery types.


- Nickel-Metal Hydride (Ni-MH) Batteries: Ni-MH batteries have a higher energy density than Ni-Cd batteries, providing longer backup times and better performance. They are also more environmentally friendly as they do not contain hazardous cadmium.


Consider the battery capacity, usually measured in milliampere-hours (mAh), to determine the backup time provided by the emergency driver. The battery capacity should be sufficient to meet the required backup duration for the specific application.


3. Verify Compliance with Safety Standards:

Ensure that the LED emergency driver kit complies with relevant safety standards and certifications, such as UL 924 (United States) or CSA C22.2 No. 141 (Canada). These standards define the performance and safety requirements for emergency lighting equipment.


4. Evaluate Mounting and Installation Options:

LED emergency drivers come in various mounting and installation options to accommodate different luminaire types and mounting configurations. Common mounting options include:


- Integral Mounting: Some LED emergency drivers can be installed inside the luminaire housing, providing a compact and integrated solution.


- Remote Mounting: Other drivers are designed for remote installation, typically in a separate electrical enclosure near the luminaires.


Choose the mounting option that best suits the installation requirements and available space.


5. Check the Battery Charging and Testing Features:

Modern LED emergency drivers often come with advanced features, including automatic battery testing and self-diagnostics. These features ensure that the battery is functioning correctly and can provide the expected backup power during emergencies. Look for drivers with battery testing and monitoring capabilities for added reliability.


6. Consider the Ambient Temperature Range:

LED emergency drivers are rated for specific ambient temperature ranges. Ensure that the driver's operating temperature range aligns with the installation environment. Extreme temperatures can affect the battery performance and overall reliability of the emergency driver.


7. Evaluate Energy Efficiency and Standby Power Consumption:

Efficiency is an important consideration to minimize energy consumption during normal operation and charging cycles. Look for LED emergency drivers with high efficiency ratings to reduce energy costs.


Also, consider the standby power consumption of the emergency driver when the luminaire is operating normally. Lower standby power consumption contributes to energy savings and environmental sustainability.


8. Consult with Manufacturers and Distributors:

If you have specific requirements or need expert advice, consult with LED emergency driver manufacturers or distributors. They can provide valuable insights and recommendations based on your application's needs.


9. Consider Warranty and Support:

Check the warranty and support offered by the manufacturer or distributor. A reliable warranty and responsive customer support can provide peace of mind and assistance if any issues arise with the emergency driver.



Selecting the appropriate LED emergency driver requires careful consideration of the LED luminaire specifications, battery type and capacity, safety compliance, mounting options, testing features, ambient temperature range, energy efficiency, and warranty. By taking these factors into account, you can ensure that the chosen emergency driver is compatible, reliable, and compliant with safety regulations, providing efficient emergency lighting during power outages or critical situations.
