What are LED Explosion Proof Lights?
Explosion-proof lighting (or hazardous environment lights ) is designed to be used in hazardous environments where there’s a risk of explosion/ignition due to the presence of flammable gasses, liquids, or dust and safety is paramount.
Engineers design explosion-proof lighting systems so that they can contain an explosion if created inside the fixture. More importantly, it’s inherently designed to prevent that explosion from escaping the fixture.
This hazardous area lighting is commonplace in industrial and commercial hazardous environments, such as oil and gas facilities, chemical plants, underground mines, water treatment plants, paint spray booths, and grain elevators.
LED explosion-proof lights are known for their great light quality and energy efficiency over traditional HID explosion-proof lights.
How To Determine If a Light Is Explosion-Proof
In the USA, the light requires a certification to UL844 standard. Beyond that, you have to determine what certification applies – Class 1 Division 1 and Class 1 Division 2 are the most common.
There are other certifications – like ATEX, that apply to other countries. In the USA, Canada, and locations near here, make sure it is UL844 certified. Canada also certifies explosion-proof lighting under CSA. Explosion proof light fixtures manufacturers are required to ensure their products conform to these standards. All of LED Lighting Supply's do.
The Difference Between Flame Proof and Explosion Proof Lighting
A flameproof light is one that’s built with materials that inhibit flames. Explosion-proof fixtures are designed to operate in an explosive environment. Never use a flameproof light in place of an explosion-proof light. Only certified explosion-proof LED lights will work in these types of environments.
Are All LED Lights Explosion Proof?
Not all LED lights are explosion-proof. The fixture tested under the UL844 certification meets explosion-proof requirements. Do not confuse vapor-proof with explosion-proof, they are not the same thing. Never use vapor-tight fixtures in an environment where explosion-proof lighting is required.
Classifications of Explosion-Proof Lighting
Class I Locations: Flammable Gases, Vapors, or Liquids
Class I are areas where vapors and/or gases can ignite and are present in enough quantity to create an explosion. Vapors are gases present over a liquid material under normal conditions. But they may emit gases that may be flammable.
Division 1 are areas where the flammable vapors or gases are present all or most of the time under normal operating conditions.
Division 2 is areas where ignitable gases or vapors are not present under normal operating conditions. Or they are areas next to Class I, Division 1 locations where barriers, walls, or doors do not exist.
Class II Locations: Combustible Dust and Hazardous Substances
These are locations that are hazardous because of the presence of combustible dust. The dust must be present in large enough quantities to create an explosion or fire. To be classified as dust, the material must be 420 microns (0.420 mm) or smaller.
Division 1 are locations containing combustible dust which is suspended in the air in quantities that can produce an explosion if ignited under normal operating conditions.
Division 2 is locations that do not have combustible dust under normal operating conditions. However, there are times when this area may accumulate dust in quantities large enough that when ignited causes an explosion.
Class III Locations: Ignitable Flyings and Fibers
Class III locations are areas that have the presence of ignitable flyings or fibers. It’s important to note that these fibers or flyings are not likely to be in suspension during normal operating conditions. These are conditions that sometimes happen but not always.
Division 1 locations have equipment that produces the ignitable fibers or flyings. This location has concentrations of ignitable flyings or fibers that exist all or some of the time under normal operating conditions.
Division 2 are locations outside of the manufacturing area that are exposed to ignitable fibers or flyings. These hazardous areas have concentrations of ignitable flyings or fibers that typically do not exist under normal operating conditions.
Groups of Class III Locations
There are no groups in Class III locations.
Explosion-Proof Lighting Groups
Explosion-proof lighting fixtures are classified into various letter groupings. These help identify the types of hazardous products and materials they can safely operate in.
Groups of Class 1 Locations
- Group A: Acetylene
- Group B: Hydrogen
- Group C: Ethylene
- Group D: Gasoline / Propane
Groups of Class 2 Locations
- Group E: Electrical-conductive dust
- Group F: Carbonaceous dust
- Group G: Agricultural and polymer dust
Explosion-Proof Lighting Zones
Zones are not part of the UL844 Explosion Proof standard but are more common in the European standard of explosion-proof classifications. The zone classification system is used to indicate what type of fixture can be used within the zone and operate safely.
Zone 0: Areas where explosive gas or dust is always present or present for long periods.
Zone 1: Areas where explosive gas or dust is sometimes present under normal operating conditions.
Zone 2: Areas where explosive gas or dust is not likely present under normal operating conditions but may occur occasionally.
Types of Explosion-Proof Lighting
Our explosion-proof lights are also IP65 or higher rated, so you can use them both indoors and outdoors. Our lights are adaptable. They can replace many existing metal halide and fluorescent fixtures including:
- Round Lights and Square Lights
- Linear Strip Fixtures
- LED Explosion Proof Flood Lighting
- Jelly Jars
- Exit Signs
How Does LED Ex-Proof Lighting Work?
The light is designed to prohibit an explosion starting within the fixture from escaping. It is not vapor-tight, as some may think. The light’s design includes a series of channels. These channels cause hot gas or flames that might start inside the fixture to cool down. By the time it leaves the fixture, it’s been defused.
When You Should Use LED Explosion-Proof Lights
Some rules and regulations mandate the use of these lights. They’re used in any environment, indoors or outdoors, where a spark from LED light fixtures or electrical equipment could cause an explosion. A refinery or underground mine is a good example of where to use explosion-proof lighting fixtures. A value-added explosion proof LED lighting manufacturer can also assist in determining if this type of lighting is needed for your project.
Explosion Proof Mounting Brackets
The main and most common mounting options available are:
- Pendant – the wiring runs through the pendant into a junction box.
- Trunnion / Yoke Mount – wired with flex pipe to a junction box.
Some custom mounts are also available:
- Slip Fitter / Pipe Mount – For pole mounting – a square fixture
- Surface Mount Arm – for wall mounting
- Stanchion Mounting – for pole mounting – a round fixture
Best Applications for LED Explosion Proof Light
LED Explosion Proof Lighting can replace, 1 for 1, metal halide and fluorescent fixtures in indoor and outdoor explosive locations and industrial settings. LED Lights will pay for themselves with energy savings in a short period. You can use explosion-proof LED lighting indoors or outdoors as they are wet location rated. You can use them in new or existing facilities for the following applications:
- Chemical processing plants
- Aircraft maintenance areas
- Enclosed fueling stations
- Paint spray booths
- Offshore oil and gas rigs
- Chemical storage units
- Ship tanks
- Oil and Gas Refineries and storage
- Grain silos
- Water Treatment Facilities
What are Intrinsically Safe Lights and How are they Different from Standard Explosion Proof Lighting?
Intrinsically safe lighting fixtures are a form of explosion-proof lighting. But they differ in the way they’re designed. By design, they cannot create an explosion or spark. For the most part, they tend to be low power, low voltage lighting, and often are battery-powered.
Can You Substitute a Class 1 Fixture for Classes 2 or 3?
No. Unlike divisions described above, you cannot swap an explosion-proof lighting fixture among classes. It is either rated for the Class you need or it isn’t.
Can you use a Division 1 Fixture of a Class in a Division 2 Area of the Same Class?
Yes, that assumes that both have the same grouping certification. For example, C1D1, Group C can substitute in C1D2, Group C areas.
Is Replacing Metal Halide and Fluorescent Explosion Proof Lights with LED Recommended?
Yes. Everyone is aware that LED lights use less energy, are more energy efficient, and last a long time. They are virtually maintenance-free. They also produce a lot less heat than an equivalent lumens metal halide light, so the fixture casing is cool to the touch.
Explosion Proof Motion Sensors and Photocells
We do. We have a motion sensor available that’s a junction box that can control multiple lights, as well as an accessory that attaches through one of the fixture’s NPT sockets. We also have a photocell junction box. You can find them in our Accessory Section.
High-Temperature Explosion Proof Lighting
Our temperature rating for explosion-proof lights is between 121F to 140F (up to 185F for Exit Signs). All of our lights list the operating temperature of each light in the specification sections of each product.
What's the Best Way to Install Explosion-Proof Lighting?
Always use a licensed and certified electrician who is knowledgeable in explosion-proof installations.
Everything in the area (light, conduit, switches, junction boxes) must be rated accordingly (not just the lights). Using an electrician familiar with these rules, guidelines, and processes will keep everything safe.
Do your Fixtures Come with a Whip or Cord?
They do not. Everything inside these areas needs to be explosion-rated. This includes junction boxes and conduits that supply power to the fixture. Unlike a normal high bay, an exposed power cord/whip does not make sense.
