What Are the Differences between Emergency Lights and Exit Signs?

Lighting plays a crucial role in our daily lives, not just for aesthetics but also for safety, especially in commercial buildings. Among the various types of lighting used in these spaces, emergency lights and exit signs stand out as critical components for ensuring the safety of occupants during emergencies. While they share the common goal of guiding people to safety, understanding the nuances between these two types of lighting fixtures is essential. Let's find the differences between emergency lights and exit signs and their varied functionalities.

Understanding Exit Signs

Exit signs are prominently displayed indicators that guide individuals to the nearest exits in case of emergencies. These signs are typically illuminated, with the word "EXIT" and sometimes an arrow indicating the direction to the nearest exit. Various types of exit signs cater to different requirements:


1. LED exit signs:** Energy-efficient and long-lasting, these signs are easy to install and maintain.

2. Incandescent exit signs: Traditional and cost-effective, but less energy-efficient compared to LED signs.

3. Photoluminescent exit signs: These signs do not rely on electricity, glowing in the dark after exposure to light.

4. Combination exit signs: These integrate features of both LED signs and emergency lighting, commonly found in commercial and industrial settings.

5. Custom exit signs: Tailored to specific requirements, such as bilingual or braille options.

Unveiling Emergency Lights

On the other hand, emergency lights serve the critical function of providing illumination during power outages or other emergency situations, aiding safe evacuation. These lights come in various forms based on their power source and structure:


1. LED emergency lights: Energy-efficient and durable, they are simple to install and maintain.

2. Incandescent emergency lights: These lights are more affordable but less energy-efficient than their LED counterparts.

3. Self-contained emergency lights: Equipped with a built-in battery and inverter, they are independent of the building's electrical power.

4. Central battery emergency lights: Connected to a central battery pack, these lights serve multiple emergency lights in a building, commonly found in larger commercial spaces.

5. Remote head emergency lights: With separate heads and batteries, they are ideal for locations with high ceilings or challenging-to-reach areas.


Differentiating Exit Signs and Emergency Lights

In summary, exit signs primarily aid in guiding individuals to the exits, while emergency lights ensure sufficient illumination during evacuations, especially in power failure scenarios. While their functions seem straightforward, it's crucial to choose the appropriate lighting fixture based on specific building requirements, considering factors such as power backup, durability, and visibility.


Despite the apparent similarities, comprehending the differences between these two types of lighting fixtures is pivotal for property owners and facility managers. Each type serves a unique purpose in ensuring the safety and security of occupants during emergencies. Selecting the right emergency lights and exit signs is critical for complying with building codes and ensuring a safe evacuation process.


Buying Guide: Emergency Lights and Exit Signs


1. Assessing Building Requirements:

Before purchasing emergency lights or exit signs, evaluate the specific needs of the building. Consider factors such as the size of the space, the number of occupants, and the layout to determine the appropriate type and quantity of lighting fixtures required for optimal safety.


2. Understanding Types of Exit Signs:

Familiarize yourself with the various types of exit signs available in the market. LED, incandescent, photoluminescent, combination, and custom exit signs offer different features and benefits. Choose the type that aligns with the building's aesthetic and functional requirements.


3. Evaluating Emergency Lighting Options:

Explore the different emergency lighting options to understand their unique attributes. LED, incandescent, self-contained, central battery, and remote head emergency lights provide varying levels of energy efficiency and functionality. Consider the specific needs of the building when selecting the most suitable option.


4. Considering Power Backup:

Factor in the importance of power backup when selecting emergency lights. Assess whether the building requires independent power sources or central battery systems to ensure continuous illumination during power outages or emergencies.


5. Prioritizing Durability and Maintenance:

Emphasize the durability and maintenance requirements of the lighting fixtures. Opt for long-lasting and low-maintenance options, such as LED lights, to minimize the need for frequent replacements and repairs.


6. Compliance with Building Codes:

Ensure that the chosen emergency lights and exit signs comply with relevant building codes and regulations. Adhering to these standards is crucial for meeting safety requirements and avoiding potential penalties or legal complications.


7. Visibility and Clarity:

Prioritize the visibility and clarity of the signs, especially in low-light or high-stress situations. Choose lighting fixtures that offer clear and prominent indicators to guide occupants swiftly and safely towards the exits during emergencies.


8. Budget Considerations:

Take into account the budget constraints while selecting the appropriate lighting fixtures. Compare the initial costs, maintenance expenses, and energy efficiency of different options to make a cost-effective and sustainable choice.


9. Installation and Maintenance Ease:

Consider the ease of installation and maintenance when selecting emergency lights and exit signs. Opt for user-friendly options that require minimal technical expertise for installation and routine upkeep.


10. Seek Professional Guidance:

Consult with lighting professionals or safety experts to gain valuable insights and recommendations tailored to the specific requirements of the building. Professional guidance can help in making informed decisions and ensuring optimal safety measures are in place.


Key Takeaway

Understanding the distinctions between emergency lights and exit signs is crucial for ensuring the safety of occupants during emergencies in commercial buildings. Selecting the right lighting fixtures based on specific building requirements is pivotal for compliance with building codes and ensuring a safe evacuation process.


  • Exit signs are illuminated indicators guiding individuals to the nearest exits in emergencies, available in various types such as LED, incandescent, photoluminescent, combination, and custom.

  • Emergency lights provide illumination during power outages or emergencies and come in forms such as LED, incandescent, self-contained, central battery, and remote head.

  • Key considerations for buying include assessing building requirements, understanding different types of exit signs, evaluating emergency lighting options, considering power backup, prioritizing durability and maintenance, complying with building codes, ensuring visibility and clarity, accounting for budget constraints, emphasizing ease of installation and maintenance, and seeking professional guidance.
