What is Class 2 Division 2 LED Lighting?

Class 2 Division 2, or C2D2, represents a specific hazardous location classification for areas containing combustible dust and fibers. After 17 years in commercial lighting, I've seen these fixtures deployed in facilities where ignitable concentrations of dust, fibers, or flying particles are sometimes present during operations. Unlike Class 1 Division 2 environments that address gases and vapors, C2D2 specifically targets particulate hazards found in manufacturing, agriculture, and processing facilities.

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

Most of our customers ask this question when planning multi-zone installations. While we can't speak for every manufacturer's hazardous location fixtures, all our Class 1 Division 2 rated lights carry dual certification for Class 2, Division 2, Groups F and G applications. This dual rating eliminates the need for separate fixture types across different hazardous zones within the same facility, simplifying maintenance and inventory management.

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

• Group F certification covers environments with combustible carbon-based dust, including coal processing plants, charcoal facilities, and carbon black manufacturing operations.
• Group G rating addresses all other combustible particulates not classified elsewhere. Wood processing facilities, grain elevators, sugar refineries, and flour mills typically require Group G compliance.

We typically recommend confirming your specific Group classification with your facility's safety officer before installation, as proper classification directly impacts insurance and regulatory compliance.

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

Every hazardous location fixture we supply undergoes rigorous testing under UL844 standard protocols. The specific Classes, Divisions, and Groups each fixture meets are clearly marked on the housing and detailed in our product specifications. Our Class 2 Division 2 lighting maintains full UL compliance, with documentation readily available for inspection authorities and insurance requirements.

Common Applications for Class 2 Division 2 LED Fixtures

From our experience working with industrial facilities, C2D2 fixtures excel in food processing plants, textile manufacturing, woodworking shops, and pharmaceutical facilities. These environments require robust lighting that can withstand occasional dust exposure while maintaining electrical safety. We often design lighting plans for grain storage facilities where seasonal dust levels fluctuate significantly.

Agricultural facilities benefit particularly from the IP65 dust-tight rating and IK08 impact resistance built into our hazardous location fixtures. The enclosed design prevents dust infiltration that could compromise both light output and electrical safety over time.

Wattage and Performance Options

Our Class 2 Division 2 fixtures range from 30 watts to 400 watts, accommodating everything from utility lighting to high-bay applications. Most customers choose 100-150 watt models for general manufacturing areas, while food processing facilities often require 200+ watt fixtures for detailed inspection work.

The integrated drivers automatically adjust to your building's 120-277V or 347-480V electrical systems without additional components. Color temperature options include 4000K and 5000K, with 5000K proving popular in quality control areas where color accuracy matters.

Installation and Mounting Considerations

Proper installation requires attention to conduit sealing and electrical connections to maintain hazardous location integrity. Our fixtures include multiple mounting options: pendant, surface mount, and yoke configurations adapt to various ceiling heights and structural requirements.

We recommend pendant mounting in facilities with ceiling heights above 20 feet, using narrower beam angles like 60-90 degrees for focused illumination. Lower mounting heights work well with 120-degree beam distributions for broader coverage patterns.

Energy Efficiency and Operating Costs

Switching from traditional hazardous location fixtures typically reduces energy consumption by 60-70% while improving light quality. The long operational life of LED technology minimizes maintenance disruptions in sensitive production environments.

Many facilities achieve additional savings through 0-10V dimming capability, adjusting light levels based on occupancy or natural daylight availability. Motion sensors can be integrated for areas with intermittent use, though we recommend consulting with safety personnel before implementing automated controls in hazardous locations.

Safety and Performance Certifications

All our fixtures carry essential certifications including DLC Premium, UL Listed, and ETL Listed approvals. These certifications ensure safety, performance, and energy efficiency while qualifying your project for utility rebates and tax incentives. DLC Premium certification guarantees the highest efficiency standards and maximum rebate eligibility.

Warranty and Warranty Support

All our lights come with at least a 5-year warranty, and all warranty support is based in the USA. We take customer support seriously, and helping you with a warranty claim is important to us. Our experienced support team understands the importance of keeping your lighting operational and will work quickly to resolve any warranty issues.
