LED Lights for Class 2 Division 2 Hazardous Locations

What is Class 2 Division 2 LED Lighting?

Class 2 Division 2 (C2D2) is a hazardous location classification for areas with combustible dust and fibers. With 15+ years in commercial lighting, I've seen these fixtures used in facilities where ignitable dust, fibers, or particles are sometimes present during operations. Unlike Class 1 Division 2, which addresses gases and vapors, C2D2 focuses on particulate hazards in manufacturing, agriculture, and processing.

The National Fire Protection Association (NFPA) outlines hazardous location classifications in NFPA 70, the National Electrical Code (NEC), which defines requirements for electrical equipment in Class 2 locations. These standards help ensure lighting fixtures meet safety requirements for environments with combustible particulates.

Will Class 1 Division 2 Certified Lights Work in a Class 2 Division 2 Environment?

Many customers ask this when planning multi-zone installations. While we can't speak for all manufacturers, our Class 1 Division 2 rated lights (model dependent) often carry dual certification for Class 2, Division 2, Groups F and G. This dual rating can eliminate the need for separate fixture types across hazardous zones, simplifying maintenance and inventory.

What are Groups F and G Associated with Our Class 2 Division 2 Lights?

• Group F - Applies to environments with combustible carbon-based dust, such as coal processing, charcoal production, and carbon black manufacturing.
• Group G - Covers other combustible particulates not in Groups E or F. Typical sites include wood processing, grain elevators, sugar refineries, and flour mills.

Confirm your Group classification with your facility's safety officer before installation, as proper classification affects insurance and regulatory compliance.

How Do I Know if Your Class 2 Division 2 Light Fixtures Are UL Compliant?

All hazardous location fixtures we supply are tested under UL844 standard protocols. The Classes, Divisions, and Groups each fixture meets are marked on the housing and detailed in product specs. Our Class 2 Division 2 lighting maintains UL compliance, with documentation available for inspection authorities and insurance.

Common Applications for Class 2 Division 2 LED Fixtures

C2D2 fixtures excel in food processing, textile manufacturing, woodworking, and pharmaceutical facilities. These environments need lighting that withstands occasional dust exposure while maintaining electrical safety. We often design lighting plans for grain storage where dust levels fluctuate seasonally.

Agricultural facilities benefit from the IP65 dust-tight rating and IK08 impact resistance of our hazardous location fixtures. The enclosed design prevents dust infiltration that could affect light output and electrical safety.

OSHA provides guidance on workplace safety in combustible dust environments through its hazardous locations standards. These regulations stress the importance of proper electrical equipment selection to prevent ignition sources where combustible particulates may accumulate.

Wattage and Performance Options

Our Class 2 Division 2 fixtures range from 30 watts to 400 watts, covering utility to high-bay applications. Most customers select 100-150 watt models for general manufacturing, while food processing often uses 200+ watt fixtures for inspection work.

Integrated drivers adjust to 120-277V or 347-480V systems. Color temperature options include 4000K and 5000K, with 5000K popular in quality control areas for color accuracy.

Installation and Mounting Considerations

Proper installation requires attention to conduit sealing and electrical connections to maintain hazardous location integrity. Our fixtures offer pendant, surface mount, and yoke configurations for various ceiling heights and structures.

Pendant mounting is recommended for ceiling heights above 20 feet, using narrower beam angles like 60-90 degrees for focused light. Lower heights work well with 120-degree beam distributions for broader coverage.

Energy Efficiency and Operating Costs

Switching from traditional hazardous fixtures typically reduces energy use by 60-70%, depending on site conditions, while improving light quality. The long life of LED technology minimizes maintenance in sensitive production areas.

Many facilities save more with 0-10V dimming capability, adjusting light levels based on occupancy or daylight. Motion sensors can be integrated for intermittent-use areas, but consult safety personnel before adding automated controls in hazardous locations.

The U.S. Department of Energy's research shows industrial facilities can achieve significant energy savings with LED upgrades. The DOE's guidance on LED lighting for industrial facilities shows proper LED use can reduce lighting energy by up to 75% while improving safety and visibility in demanding environments.

Safety and Performance Certifications

Our fixtures carry key certifications: DLC Premium (energy efficiency and rebate eligibility), UL Listed and ETL Listed (electrical safety and product compliance). DLC Premium ensures high efficiency and maximum rebate eligibility. NSF certification applies to sanitation and cleanability, not electrical safety. Each certification addresses its specific scope.

Warranty and Support

All our lights include at least a 5-year warranty, with USA-based support. Our team understands the importance of keeping your lighting operational and will work quickly to resolve any warranty issues.

Expert Guidance for Your Hazardous Location Project

Navigating Class 2 Division 2 requirements demands specialized knowledge our team has developed over decades of industrial lighting projects. Our product specialists work with facility managers to create custom lighting plans that ensure proper illumination and compliance. We provide detailed energy savings calculations based on your current fixtures, operating hours, and utility rates to show exact cost reductions. This technical expertise helps ensure your investment delivers safety and efficiency from day one.

Common Mistakes and How to Avoid Them

Many contractors and facility managers make mistakes on C2D2 installations by underestimating hazardous location requirements. These errors can lead to code violations, fixture failures, and safety risks.

• Using regular industrial fixtures where dust exposure occurs. Always check area classification, as even intermittent dust requires C2D2-rated equipment.
• Skipping conduit seals or placing them too far from the fixture. NEC requires sealing fittings within 18 inches of hazardous location fixtures.
• Underestimating light output in dusty environments. Plan for 20-30% higher wattage, as dust buildup reduces illumination over time.
• Mixing certified and non-certified components. Every part in the circuit must maintain the same hazardous location rating.
• Assuming Class 1 Division 2 fixtures always work in Class 2 applications. Verify dual certification for Groups F and G before ordering.
• Adding motion sensors or dimming without safety approval. Automated controls in hazardous locations may trigger extra code requirements.
• Ignoring IP ratings. Hazardous location certification alone is not enough; IP65 dust-tight sealing is needed in Group G applications.
