Frequently Asked Questions

There are a lot of unknowns around Class 1 Division 1 lighting. So we asked our customers what questions had. Scroll down to find answers to our common questions or call (888) 423-3191 to speak with a lighting expert.

General

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 explosive environments and hazardous conditions 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 and/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 certified for Group B. Please check the specifications for each light if you specifically need C1 D1 Group B.

Is Class 1 Division 1 Explosion Proof?

Yes, C1D1 is explosion-proof under UL844 testing standards.

Is Class 1 Div 1 a Stricter Class?

Yes, it is. 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 explosive materials. C1D1 handles ‘always present dangers. Division 2 in Class 1 is for ‘sometimes present’ environments.

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

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

Energy saving
Reduced maintenance
Improved quality of light
Long Lifespan

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

What are the typical lifetimes of LED Class 1 Div 1 light fixtures?

These c1d1 lighting fixtures are rated to run for a very 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.

Hazardous environment classification

Are there Specific Certifications or standards that Class 1 Division 1 LED lights must meet?

All the Class 1 Division 1 light fixtures on this page meet and pass the UL844 standard for explosion proof lighting.

Is Class 1 Div 1 the Same as Atex Classifications?

Class 1 Division 1 is a UL Classification of explosion-proof lighting that we use in North America. ATEX is a different standard not used in this country. Lights that are UL rated and tested for C1D1 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 i div 1 lighting.

What are some Industrial Applications for Class 1 Division 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

These fixtures are high-impact, heavy aluminum frames with thick tempered glass.

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

Does Class 1 Div 1 Light Come with Power Cords?

Not always. Everything inside the C1 D1 area needs to also be Class 1 Division 1 rated. That includes the conduit, junction boxes, and switches.

What Are the Best Applications of Class 1 Division 1 Lighting?

The best applications of Class 1 Division 1 lighting are hazardous, explosive environments. This is where explosive gases or materials (such as dust) are always present in the atmosphere.

While these applications are typically inside a room or facility, it’s not limited to that environment. There are times when outdoor locations also need Class i Division 1 lighting, like offshore oil/gas drilling platforms.

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

LED Explosion Proof Light Installed

Is Class 1 Div 1 LED Lighting Intrinsically Safe?

It can be. But there’s a difference between explosion-proof and intrinsically safe lighting.

Explosion-proof fixtures design handles the case an explosion starts inside the fixture. The explosion would channel and cool inside the fixture. So, when it comes to the point to escape the fixture, it does not result in an explosion in that environment.

Intrinsically safe lights are different. They’re designed in such a way that they are not capable of creating an explosion or spark. They are low-voltage battery-operated fixtures.
