 The Lighting Center offers Class 1 Div 1 LED lighting that's designed to remain safe in hazardous environments.

Our Class 1 Div 1 LED lighting products have been designed and built to be used safely in the presence of hydrogen, acetylene and other petrochemicals & gas fumes. Commonly our class 1 div 1 lighting LED (C1D1) are used in petrochemical tanks, boat yards & marine applications, plants, oil rigs, spray paint booths, and more. 

Our Class 1 Div 1 LED lights not only run safely in these dangerous & hazardous environments and are explosion proof, but they also reduce energy costs up to 75% and improve safety through high quality light output.

Class 1 Division 1 LED Lighting

Choosing the appropriate light fixtures for areas designated as hazardous is much harder than choosing lights for other commercial applications. There are a lot more considerations to keep in mind, not just the lumen output. The Occupational Safety and Health Administration, commonly known as OSHA, has regulations for hazardous environment lighting that are very specific regarding the characteristics and features of lights allowed for use in such areas.

LED lighting designed for industrial use is usually the go-to lighting for industries. However, not all industrial quality LED lights are suitable for hazardous environments. The features of an LED light fixture must therefore be assessed to determine if it can withstand the threats that environment intrinsically has.

Electrical equipment that is faulty can ignite or cause explosions in a hazardous environment. Areas that have concentrations of explosive vapors or dust require light fixtures with safe electrical components and special wiring.

Examples of hazardous locations include grain bins, paint finishing applications, aircraft hangars, gasoline stations, and oil and gas facilities. Such areas might have substances of a hazardous nature in sufficient quantities in the air to ignite or cause an explosion.

In the U.S., hazardous locations are classified in the Articles 500-506 of the National Electric Code® (NEC) and Publication 70 of the Fire Protection Association (NFPA). The NFPA has classified these areas in terms of classes, followed by divisions then zones. These classifications point to the hazardous conditions prevalent in an area. OSHA, whose main mission is to stop work-related illnesses, injuries, and deaths, has adopted the NEC classifications.

These environments have vapors or flammable gases present in the air in quantities sufficient to produce an ignition or explosion.


Class 1 Division 1 locations have:

Flammable vapors or gases in ignitable concentrations existing in them during normal operations.

Vapors or gases in ignitable concentrations frequently occurring due to maintenance or repair operations or at times due to leakages of products

Processes or equipment that may break down or become dysfunctional, releasing ignitable quantities of flammable vapors or gases. Such occurrences could also cause electric equipment failure

What Makes LED Class 1 Div 1 Lights Different?


If the wrong light fixtures are used in Class 1 Division 1 locations, they have a very high potential of causing catastrophic chain reactions that lead to explosions. The traditional HID lamp has an internal pressurized atmosphere. In case the delicate glass bulb suffers damage, it can release an electric spark that could ignite flammable gases or vapors in its surroundings.

Sparks in traditional light fixtures could also be caused by a faulty or overloaded electrical system due to the massive wattages HID lamps utilize. The bulbs also generate light through an oxidative process that produces a lot of infrared energy. This energy causes thermal buildup when the lamp has to operate continuously for long hours. In such high temperatures, an explosion becomes imminent.

LED lights, however, do not have pressurized glass bulbs or tubes that can fracture on impact or through vibrations. In simple terms, these lamps produce light when electrons travel around within their semiconductor structures. To make them hardy, they are built with rugged casings and frames that are scratch-resistant, crack-resistant, and fracture-resistant. They also have lenses made of tempered glass.

In hazardous locations, regular LED lights can still pose a threat of explosion. And while these lights offer better performance compared to traditional lights, thanks to their inbuilt heat sinks that excellently dissipate heat, they are not ideal for hazardous lighting locations as they lack the proper components.

LED Class 1 Div 1 light fixtures have casings made of ultra-durable aluminum that not only protect the internal components from damage but also ensure that any sparks within the fixtures are contained and not released into the atmosphere in case of an explosion.

Intrinsically Safe: LED Class 1 Div 1 Lighting

Some terminologies used in regards to these industrial LED lights can be quite confusing, so we’ll break it down. Explosion proof LED lights can contain an explosion and hinder it from advancing into a fire. Intrinsically safe light fixtures, on the other hand, operate on lowered electrical loads, lowering ignition risk. However, genuine LED Class 1 Div 1 lighting should have its Class, Division, and Group category clearly marked for ease of selection.

Class 1 div 1 rated lights are built to eliminate sparking, which would otherwise potentially ignite in a location with ignitable fumes in the area. We built our class 1 division 1 lighting fixtures to eliminate sparking, making them intrinsically safe LED lights that will remain safe in the harshest and hazardous conditions.

Our explosion proof, Class 1 Division 1 LED light fixture products come in one shape, allowing us to perfect it and make it the best in its class and division, while offering the best possible price.

Alternatively, you can replace hazardous location commercial metal halide or high-pressure sodium class 1 division 1 hazardous location luminaries in your existing explosion proof class 1 division 1 with our industrial grade retrofit units that still meet class 1 division 1 explosion proof light safety standards. Our retrofits are also DLC approved, and offer equivalent lumen output with less power consumption.

Talk to Us about Class 1 Division 1 LED Lights

The proper application of class 1 div 1 LED lighting fixtures is critical to maintain a safely operating lighting system where perpetual or consistent petrochemicals or other ignitable concentrations & hazardous gases are exposed to the lighting system. For hazardous work site areas where ignitable gases are more contained or ventilated, then a Class 1 Div 2 lighting fixture may be a suitable option for that location.

Our perfected class 1 division 1 LED lighting fixture products are designed to meet qualifications for these environments along with a UL listing and are DLC approved.

We found that matching this class 1 div 1 light qualification with LED technology allows for companies to maintain a safe lighting system in hazardous locations while reducing energy costs by up to 75% and reducing overall costs of a typical explosion proof class 1 div 1 lighting system.

Over the years, we have installed LED Class 1 Div 1 lights in many hazardous locations. We are experts in explosion proof lighting. Let us help you switch to LED technology easily and effortlessly.
