Class 1 Division 1 LED fixtures

Class 1 Division 1 LED lighting refers to luminaires engineered and certified for operation in environments where flammable gases, vapors, or liquids are present under normal operating conditions. These systems are designed to contain any internal ignition source and prevent outward flame propagation, ensuring safety in highly hazardous industrial spaces. Class 1 Division 1 LED fixtures combine high-efficiency LED performance with rugged, explosion-proof enclosures, enabling reliable illumination, extended service life, and compliance with industrial safety regulations.

Division 1 installations form a critical subset of the wider industrial explosion proof lighting classification system used across hazardous facilities.

What Is Class 1 Division 1 LED Lighting?

Class 1 Division 1 LED lighting is a category within the National Electrical Code (NEC) that defines fixtures appropriate for environments where flammable gases or vapors may be present under normal operating conditions. Fixtures rated for Class 1 Division 1 are constructed to safely contain any potential internal ignition sources, such as sparks or excessive heat, ensuring they cannot ignite the surrounding hazardous atmosphere.

These fixtures are typically tested and labeled under standards such as UL844 in North America and may also be available with ATEX or IECEx certifications in international markets. Unlike fixtures designed for Division 2 or non-hazardous zones, Class 1 Division 1 LED lighting must meet more stringent safety and containment requirements due to the continuous presence of explosive atmospheres.

For a complete technical overview of hazardous location classifications, certification standards, and fixture selection methodology, refer to our Explosion-Proof Lighting Standards & Selection Guide.

Where Class 1 Division 1 LED Lighting Is Used

Class 1 Division 1 LED lighting is used in industrial environments where flammable gases, vapors, or liquids may be present during normal operations. Common applications include:

  • Oil and gas production platforms and refining operations

  • Petrochemical and chemical processing facilities

  • Fuel storage terminals and loading docks

  • Paint spray booths with solvent vapors

  • Pharmaceutical production areas with volatile solvents

  • Any facility where hazardous materials are in continuous use

These environments require lighting that maintains both safety and compliance without sacrificing performance or energy efficiency.

For areas where hazardous materials are only present under abnormal operating conditions, explore our Class 1 Division 2 LED lighting solutions.

Frequently Asked Questions About Class 1 Division 1 LED Lighting

1. What environments require Class 1 Division 1 LED lighting?

Class 1 Division 1 LED lighting is required in areas where flammable gases or vapors are present during normal operating conditions, such as refineries, chemical plants, and oil & gas production facilities.


2. How do Class 1 Division 1 LED fixtures differ from Division 2 fixtures?

Class 1 Division 1 fixtures are designed for continuous presence of hazardous atmospheres and must meet stricter containment and certification standards, whereas Division 2 fixtures are intended for areas with only occasional hazardous exposure.


3. What certifications should a Class 1 Division 1 LED fixture carry?

Look for certifications such as UL844 in North America, and ATEX or IECEx for international installations. Fixtures must also be labeled with their Class, Division, and temperature rating.
