What is Class 1 Div 1 LED Lighting?

Class 1 Division 1, or C1D1, is a classification of explosion ratings. It’s designed to work in hazardous environments where ignitable concentrations of flammable combustible vapors, liquids, or gases are always present.

What is a Class 1 Division 1 Area?

Class 1 Areas are groups. Groups are categorized by the type of material found. The most common groups are:

• (A) Acetylene
• (B) Hydrogen
• (C) Ethylene or propane
• (D) Propane, butane, methane and benzene.

Note: all of our class 1 div 1 lighting are certified for Groups C and D. Some are licensed for Group B. Please check the specifications for each light if you specifically need C1 D1 Group B.

What are Industrial Applications for Class 1 Division LED Lighting?

• Oil and Gas Industry – petroleum refineries, oil platforms, drilling rigs
• Chemical Manufacturing
• Ocean, Marine, and Aerospace Industries
• Food and Alcohol Production, Distilleries
• Electrical Power Generation Industry (Natural Gas)
• Waste Treatment Facilities and Plants
• Metal Treatment and Processing

What are the Benefits of Using Class 1 Div 1 LED Lighting?

Like other LED lights, hazardous location explosion-proof lights provide the same key benefits.

• Long Life: Years of maintenance-free life without bulb or ballast changes reducing or eliminating maintenance costs
• Reduced Energy Bills: You can expect to reduce your energy costs and lighting bills by 50% to 75% with lower energy consumption versus traditional lighting.
• Energy Efficiency: LED fixtures are known for their efficiency and energy savings. They convert most of the electricity used into light. Very little heat is created. This will reduce your HVAC load and is a cost-effective lighting solution.
• Safer Areas: LED Lights are reliable, producing high-quality lighting for a long time versus metal halide and fluorescent lighting. It keeps the areas lit by LED high bays safer and well-lit.
• Instant On: LED Lights turn to 100% the moment you hit the light switch.
• Easy to install: There is nothing difficult about installing and wiring our high bay lights for either new installations or replacing old high bays. All instructions are included.

They also meet the certification requirements needed in Class 1 Div 1 applications. They will provide a safe lighting environment and work well in a hazardous location requiring repair or maintenance operations.

Class 1 Division 1 LED Lights FAQ

What Certifications or Standards Must Class 1 Division 1 LED Lights Meet?

All the Class 1 Division 1 LED fixtures listed here meet and pass the UL (Underwriters Laboratory) UL844 standard for hazardous location lighting and have been tested to that standard.

Is Class 1 Division 1 the Same as ATEX Classifications?

Class 1 Division 1 is a UL classification used in North America. ATEX ratings are a different standard not used in this country. UL-rated and tested for C1D1 lights do not always qualify for ATEX certification and vice versa. In other words, a similar ATEX classification to C1D1 does not mean the light has met UL standards for class 1 div 1 lighting.

Is Class 1 Division 1 the Highest Classification of Hazardous Location Lights?

Yes Class 1 Division 1, or C1D1, is the strictest of all standards. It’s designed for an environment where danger is always present.

What's the Difference Between Class 1 Division 1 and Class 1 Division 2?

The main difference is the presence of gas or other hazardous materials. C1D1 handles 'always present' dangers. Class 1 Division 2 is for 'sometimes present' environments.

What are the Typical Lifetimes of LED Class 1 Div 1 Light Fixtures?

These class 1 division 1 LED fixtures are rated to run for a long time. Running these lights for 12 hours a day, 365 days a year – you can expect 10+ years of life from them without maintenance, bulb, or ballast changes.

What Additional Items Do You Need When You Install Class 1 Div 1 LED Lighting?

Everything the Class 1 Division 1 light is connected to inside the room must also be Class 1 Division 1 rated. There are some accessories available. But they’re limited due to the special nature of this fixture.

You may also need to supply a power cord. Everything inside the C1 D1 area must also be Class 1 Division 1 rated. That includes the conduit, junction boxes, and switches.

What Materials are Class 1 Div 1 LED Lighting Made Of?

These hazardous area class 1 division 1 fixtures are high-impact, heavy aluminum frames with thick tempered glass.

Each fixture has an impact rating of IK10 – the highest impact rating available.

Can You Hard Wire LED Lights in Class 1 Div 1 Areas?

Yes, work with a qualified electrician certified in this type of installation. And, there can not be any exposed wires.

Caution: Always hire an experienced and qualified electrician who understands class 1 division 1 lighting requirements to do the job for you.
