When it comes to hazardous or high-risk environments, safety and reliability are non-negotiable, which is where LED explosion proof lighting comes in. Designed to withstand extreme conditions such as flammable gases, combustible dust, and volatile chemicals, these specialized lights ensure both protection and efficiency.
In this guide, we’ll walk you through the key advantages of explosion proof LED lighting and highlight some of the best products available for industrial and commercial use.
Explosion proof lighting refers to lighting fixtures designed for environments with chemicals, gases, high heat, flammable dust, and liquids. They are specially designed with a rugged enclosure to contain any explosion within the light fixture and prevent it from causing a fire outbreak or igniting the flammable materials in the environment.
Explosion proof lighting reduces the risk of ignition that could occur when flammable materials come in contact with sparks from the light bulb or even the heat generated by regular light bulbs. This is achieved by enclosing all the light fixture components in a durable compartment that can contain any internal explosion. Although explosion proof lights have rigid lenses, they are not always vapor-tight; therefore, they do not function the same as vapor-tight lights.
According to the National Electric Code (NEC) published by the National Fire Protection Association (NFPA), it has been mandated that all lighting fixtures used in hazardous locations should be explosion-proof. This is a measure that has to be taken to improve the safety of workers.
As a result, explosion proof lights have been specially designed and approved for these locations, considering the dangers posed during work activities. Ex-proof lights have a robust enclosure that secures the light bulb, wires, and sockets against contact with explosive materials in the air.
On the flip side, ordinary lighting fixtures do not offer such protection, which means the bulb, and wiring, are exposed to flammable materials. For this reason, you should use explosion proof lights to improve the safety of workers in risky environments.
Different explosion proof lights use various bulb technologies, such as high-intensity discharge (HID) bulbs and halogen bulbs, but choosing LED light has many advantages. The major one is cost-efficiency. Although LEDs have higher initial costs, their maintenance cost is low. Unlike other bulbs, they can last over 50,000 hours, so you don't have to replace them so often.
LED explosion proof lights are environmentally friendly. They contain no harmful chemicals or UV rays, making them safe to us. LEDs can also be recycled since they are eco-friendly.
In addition, LED bulbs are versatile. They work well in cold weather and do not dim or flicker like fluorescent bulbs. LEDs maintain their lumen output well; brightness decreases slowly over time. The light output reduces slowly until burnout time.
In industrial facilities with high ceilings and hazardous environments, finding lighting that is both powerful and safe can be a challenge. LED high bay explosion proof lighting is designed to address this challenge. Built for warehouses, factories, oil refineries, and chemical plants, these fixtures provide brilliant illumination while ensuring maximum protection against flammable gases, vapors, or dust. By combining the efficiency of LED technology with explosion proof housing, LED high bay lights deliver long-lasting performance, reduced energy costs, and dependable safety in even the toughest conditions.
LED linear explosion proof lighting is an ideal solution for hazardous locations. Designed with a slim, elongated profile, these fixtures provide wide and even light distribution, making them perfect for production lines, walkways, and confined industrial spaces. They combine the safety of explosion proof construction with the energy savings and durability of LED technology. These fixtures provide clear, shadow-free lighting while resisting harsh conditions.
Explosion proof LED floodlights are designed to operate safely in hazardous environments, such as oil refineries, chemical plants, mines or gas storage facilities.
They comply with strict global explosion proof standards, e.g., ATEX in the EU, NEC Class/Division in the US, IECEx internationally. LEDs produce significantly less heat than traditional lighting, reducing the surface temperature of the fixture. Their tough, corrosion-resistant housings serve as a protective barrier. Made from strong materials like reinforced aluminum or stainless steel, these enclosures are sealed to IP66/IP67 standards to keep flammable substances, water, and dust from reaching the internal components.
At their core, these LED jelly jars meet the strictest global explosion-proof certifications. Using LED technology, these jelly jar lights offer both safety and efficiency. They produce very little heat, lowering the risk of ignition, last over 50,000 hours to reduce maintenance in hard-to-reach places, and turn on instantly when needed. Their compact design is ideal for spot lighting, such as equipment bays or walkways, but their main benefit is transforming ordinary lighting into reliable safety protection.
● Durability: Explosion-proof lights are highly durable. They can withstand high pressure and tough working environments due to their sturdy makeup. These are your best choice for confined work spaces.
● Mobility: Explosion-proof lights have thick lens enclosures made to resist vibrations. They can be transported effortlessly from one location to another without the risk of shattering or malfunctioning. This makes explosion-proof lights the most suitable choice for businesses requiring movable lighting.
● Lesser Heat Emission: Explosion-proof LED lights emit about 90% less heat than incandescent bulbs and require lower voltage. This reduces the chances of heat causing sparks in the light fixture, reducing the occurrence of an internal explosion.
● Efficiency: Explosion-proof lights are highly efficient. They consume less energy and produce high-quality lighting. These LEDs can last up to 100,000 hours, and their durable enclosures reduce the risk of leakage or breakage that could shorten bulb life.
● Multiple Options: Explosion-proof lights have multiple application options. You can mount them using different methods like poles, rails, and other mounts, increasing the flexibility of this light fixture.
Hazardous locations are classified according to the category of flammable material present in the environment. Explosion-proof lights are designed to fall into different classifications of risky locations. This classification is based on National Fire Protection Association (NFPA) 70®, National Electric Code® (NEC). The most common system uses class, division, and group categories.
| Class | Division | Description |
|---|---|---|
| 1 | Flammable gas, flammable vapors, or liquids are present | Normal hazardous operating conditions |
| 2 | Combustible dust is present within the environment | Abnormal hazardous operating conditions |
| 3 | Flammable fibers and flyings are present within the environment | — |
| Group | Classification |
|---|---|
| A | Acetylene |
| B | Hydrogen, butadiene, ethylene oxide, propylene oxide, and acrolein |
| C | Ethylene, cyclopropane, and ethyl ether |
| D | Acetone, ammonia, benzene, butane, ethanol, gasoline, hexane, methane, methanol, naphtha, natural gas, propane, and toluene |
| E | Combustible metal dust: aluminum, commercial alloys, and magnesium |
| F | Combustible carbonaceous dust: carbon black, charcoal, coal, and coke dust |
| G | Other combustible dust: chemicals, flour, grain, plastic, and wood |
People often confuse these two types of lighting; while both aim to prevent fire outbreaks, they do so in very different ways.
Explosion proof lights are designed to contain any explosion within the light fixture to prevent it from spreading outside. Their durable covers act as a barrier so, in case of an explosion, the spark will be contained. This prevents the spark from igniting the flammable particles and gases in the atmosphere, thereby preventing a fire outbreak.
On the flip side, intrinsically safe lighting is powered by low-voltage bulbs like LED bulbs. They are designed to limit the amount of energy consumed so that sparks cannot occur, preventing internal explosions. Intrinsically safe lights often use batteries and rechargeable batteries instead of electricity.
Unlike explosion-proof lights, intrinsically safe lights are designed to prevent explosions instead of containing them. A typical industrial intrinsically safe light circuit will have a temperature sensor installed to limit the amount of energy consumed.
Explosion proof lights are enclosed in hard lenses to reduce the chances of a fire outbreak when a light bulb ignites a flammable material. They are designed to contain the explosion to prevent its spread.
LED explosion proof lights are durable, portable, energy-efficient, and provide high lumen output. Explosion proof LED light has low heat emission, which helps to reduce the risk of explosion.
