What is an Emergency Lighting Inverter System?

When mapping out building emergency exit routes, do you consider the lighting that will guide patrons towards a safe exit in the event of a power outage? By implementing an effective emergency lighting system and installing lighting inverters, you can better secure safe exiting procedures and protocols. Therefore, in the content below, we answer the question: what is an emergency lighting inverter? Continue reading to explore two lighting inverter types and discuss applications by industry.

Emergency Lighting Inverter 101

Before defining the purpose of an emergency lighting inverter, it is paramount to understand the basics of a traditional lighting inverter.

A lighting inverter translates DC battery power into standard AC voltages to provide back-up for lighting systems in the event of an emergency. Additionally, some inverters are designed to generate a continual, filtered power, coined an Uninterruptible Power Supply.

Created for many applications, the design of emergency lighting inverters extends beyond emergency lighting applications. For example, fire alarms systems, exit lighting, lighting control systems, and other safety equipment are often supported by an emergency lighting inverter. Therefore, emergency lighting inverter systems are paramount for generating and maintaining light and power during electric outages.

Types of Inverters

There are two different installation approaches when it comes to lighting inverters: central lighting and dispersed lighting.

Central Lighting

Matching its name, a central lighting inverter generates emergency lighting and back-up power through a centralized lighting unit. Offering multiple lighting inverter design options that minimize maintenance requirements and optimize emergency lighting performance, this lighting system is capable of powering both existing indoor and outdoor fixtures.

Although central lighting inverter solutions offer lower operational and maintenance expenses, they do require a higher initial capital investment. However, the initial costs may be outweighed by the easy installation and maintenance tasks due to its single, central location and battery system.

Dispersed Lighting

In contrast to a centralized lighting solution, dispersed lighting operates by supplying each individual light’s power with its own battery. As a result, in the event you experience an issue with a single emergency light, you can rely on other dispersed lighting to keep your building or exterior illuminated properly.

However, one consideration with dispersed lighting measure includes the long-term cost of ownership and upkeep. Despite lower initial expenses of purchasing and installing dispersed lighting systems, this lighting solution may result in a higher total cost of ownership. Additionally, the manual upkeep may feel more cumbersome than a central lighting system as you must test each individual light to examine both batteries and functionality and ensure it meets proper safety standards.

The UL924 Standard

As emergency lighting inverters supply uninterrupted power to lighting systems during an outage, it is essential that they adhere to the UL924 standard and the NFPA’s life safety requirements. The UL924 standard requires that every facility must have a compliant emergency lighting inverter effectively in place. Additionally, the inverters are also expected to have the capability of remaining lit for at least 90 minutes when the power goes out.

Lighting Inverter Supply only works with UL 924 standard, tested, and certified systems, providing you with the industry’s highest capacity and efficiency systems.

Emergency Lighting Inverter System Applications

Emergency lighting offers endless solutions spanning across residential and commercial applications. Below, we discuss five different industries that especially benefit from implementing emergency lighting inverters.


Today’s industrial processes have become incredibly complex due to automation, computerization, modernized equipment, and detailed quality control metrics. Additionally, many facilities and manufacturing plants use variable frequency drives, electric motors, and other production components that create a harsh electrical environment.

Therefore, to combat the high consumption of power and lighting, the industrial field must have proper emergency lighting solutions in place when outages occur to ensure safe and regulated operations and procedures. Protecting these controls and their applications such as wastewater treatment, automated manufacturing, food processing, and parts fabrication requires electrical power solutions that deliver isolated, regulated, transient, and noise-free sine wave power.


Medical-grade power quality cannot and must not be compromised. In the medical field, losing lighting or power can mean the difference between life and death. Healthcare industry experts believe that as many as 75% of electronics-based equipment disruptions and failures are attributed to “power quality” issues. What would it mean to your hospital or healthcare facility if 7 out of 10 equipment problems could be prevented?

Therefore, hospitals and other medical facilities go through extensive lengths to generate and maintain a consistent source of lighting and power throughout the entire facility. The solution is to strategically install products that provide voltage regulation, isolation, and power distribution for medical imaging diagnostics/treatment equipment, in addition to battery backup (UPS) for “patient-vicinity” medical diagnostics and monitoring equipment.


Within the mining industry, all safety measures and protocols must work effectively. Therefore, most control functions are fully automated, including critical conveyor systems. As a result, this industry cannot work without a reliable UPS battery backup for the controlling server that promises a high tolerance to bad incoming power.

Retail and Commercial

With the current incorporation of technology in today’s retail and commercial industry, it is crucial to establish a reliable and regulated voltage and backup power to protect critical operations and data. In addition to general I.T. equipment, emergency lighting and power inverter applications include surveillance cameras, security systems, and network communications. Furthermore, it is paramount for retail businesses to include battery backup protection during point of sales, including the network hardware responsible for communicating sales transactions.


Keeping educational facilities running with efficient power quality plays a key component in ensuring a proper educational experience. Since computers and other electronic devices are now commonplace within classrooms and other educations venues, there is certainly a requirement for “clean power.”

To provide protection from electrical noise and voltage transients, “clean power” panelboards are often installed to feed computer lab rooms, and to protect sensitive A/V equipment within the performing arts center. Each panelboard is supplied power from a multi-shielded, K-13 rated, computer-grade isolation transformer, typically together with a surge protection device (SPD).

Additionally, uninterruptible power is paramount for school security systems such as video surveillance cameras and safety measures for lockdown procedures. Battery backup is also needed for critical systems that allow the school to communicate both on campus and with local police and fire departments.
