Class 1 Division 1 LED Lighting for Hazardous Locations

Class 1 Division 1 lighting is designed for hazardous environments where flammable gases or vapors are present continuously or under normal operating conditions. As part of broader commercial LED lighting solutions, these systems are engineered to contain internal ignition sources and prevent interaction with the surrounding environment.

C1D1 lighting is commonly used in high-risk industrial settings where safety, compliance, and reliability are critical to daily operations.

Key Benefits of Class 1 Division 1 Lighting

Maximum Safety Compliance

Designed for environments with continuous exposure to hazardous gases or vapors.


Durable Construction

Sealed housings and rugged materials ensure safe operation in harsh environments.


Reliable Performance

Consistent lighting output in demanding industrial conditions.

What Is Class 1 Division 1 Lighting?

Class 1 Division 1 refers to hazardous locations where flammable gases, vapors, or liquids are present continuously or frequently under normal operating conditions. Lighting used in these environments must be designed to prevent ignition and ensure safe operation.

Explosion proof lighting fixtures used in C1D1 environments are built to contain any internal sparks or heat within the fixture housing, preventing interaction with the surrounding hazardous atmosphere.

Where Class 1 Division 1 Lighting Is Used

  • Oil and gas facilities
  • Chemical processing plants
  • Refineries
  • Fuel storage areas
  • Offshore and marine environments
  • Industrial manufacturing with hazardous materials
