Our Class 2 Division 2 LED Lights for Combustible Dust Locations include hazardous-location fixtures for classified industrial areas involving combustible dust. Available fixtures support Class II Division 2 applications, including locations associated with Group F carbonaceous dusts and Group G dusts such as flour, grain, sugar, wood, and certain plastic or chemical dusts. Catalog variations include T-ratings, ambient temperature ranges, environmental ratings, voltages, lumen outputs, optics, and controls compatibility. Mounting configurations may include pendant, ceiling, wall, yoke, and surface options. Depending on the model, fixtures may carry UL, ETL, CSA, or other applicable listings and certifications. Some models carry multiple classifications covering both Class I gas or vapor hazards and Class II combustible-dust hazards.
Common applications for these LED fixtures include classified areas in grain handling and storage facilities, food processing plants, woodworking operations, carbon processing facilities, plastics and chemical manufacturing plants, and pharmaceutical production facilities. Group F applications may involve coal, charcoal, or carbon black dust, while Group G applications may involve flour, grain, sugar, wood, and certain plastic or chemical dusts. Available models also vary by dust-ingress requirements and wet-location, washdown, or corrosion-resistance ratings.
What Is Class II Division 2 LED Lighting?
Class II Division 2, commonly shortened to C2D2, applies to hazardous locations involving combustible dust where the dust is not normally suspended in the air in quantities sufficient to create an ignitible mixture, but hazardous conditions can develop because of abnormal or infrequent malfunction.
Division 2 can also be relevant where dust accumulation may interfere with the safe dissipation of heat from electrical equipment or could become ignited by abnormal equipment operation.
This classification addresses combustible dust, not ignitible fibers or flyings, which fall under Class III. The classification for the actual installation area should be established before selecting the luminaire.
Groups F and G and Why Dust Accumulation Matters
Class II Division 2 applications commonly involve Groups F and G.
| Dust Group | Common Examples |
|---|---|
| Group F | Carbonaceous dusts such as coal, carbon black, and similar materials depending on classification |
| Group G | Grain, flour, starch, wood, plastic, chemical, and other nonconductive combustible dusts depending on classification |
Group E involves conductive combustible dusts such as certain metal dusts and is associated with Class II Division 1 treatment when present in hazardous quantities. Do not assume a fixture suitable for Groups F or G is suitable for a conductive-metal-dust application.
Dust layers matter even when dust is not normally suspended in an ignitible cloud. Accumulation on the luminaire can affect heat dissipation, so the fixture’s temperature marking, ambient range, construction, and maintenance conditions need to fit the application.
Matching the Fixture to the Facility
Start with the documented Class II Division 2 classification and dust Group. Then account for the actual environment. Moisture, washdown, corrosion, chemical exposure, vibration, impact, outdoor conditions, ambient temperature, voltage, and mounting may require additional product features or ratings.
Lighting output should be selected from the physical space rather than from a standard wattage assumption. Mounting height, optics, lumens, fixture spacing, obstructions, foot-candles, and uniformity determine how many fixtures are needed and where they should be installed.
These classified areas may be found in portions of grain-handling facilities, food and ingredient processing plants, coal operations, woodworking facilities, plastics processing, and other industrial spaces where combustible dust may be present. Actual classifications can differ substantially within the same facility.
Electrical System, Listings, and Installation
The fixture rating does not make the remainder of the installation suitable by itself. Wiring methods, conduit or cable systems, boxes, fittings, and switches, seals where required, grounding, bonding, and other electrical components must also meet the requirements for the classified location.
Installation should be completed by qualified electrical professionals experienced with hazardous locations and follow applicable codes, the equipment listing, manufacturer instructions, and local requirements.
Safety and Performance Certifications: Listings and markings are model-specific. Products may carry UL, ETL, CSA, or other applicable certifications depending on the fixture and project. Check the exact product for its Class II Division 2 marking, dust Group, temperature and ambient ratings, voltage, environmental protection, mounting, and controls.
A fixture carrying a Class I gas/vapor rating is not automatically suitable for a Class II dust location. If one product carries multiple hazardous-location ratings, each applicable marking should appear on the exact model.
Warranty and Lighting Design Support
Many Class II Division 2 LED fixtures include a 5-year warranty unless otherwise specified, with warranty support based in the USA.
Once the area’s hazardous classification is documented, LED Lighting Supply can help narrow the fixture choices and provide a hazardous-area lighting design showing expected fixture quantity, placement, mounting heights, foot-candles, and uniformity.
If the area is classified as Class II Division 1, use equipment specifically suitable for that Division rather than assuming a Division 2 fixture is acceptable.
Class 2 Div 2 Lighting FAQs
What Does Class II Division 2 Lighting Cover?
Class II Division 2 lighting is intended for hazardous locations involving combustible dust that is not normally suspended in ignitible quantities, but where hazardous conditions may develop because of abnormal or infrequent malfunction. It also applies where dust accumulation can interfere with heat dissipation or become ignited by abnormal equipment operation.
How Do I Choose A Class II Division 2 Fixture?
Select a fixture by first matching its marking to the documented Class II Division 2 classification and applicable dust Group. Then confirm its temperature marking, ambient range, voltage, environmental protection, mounting, controls, and any needed resistance to moisture, washdown, corrosion, chemicals, vibration, impact, or outdoor exposure.
Are Group F And Group G Fixtures Suitable For Conductive Metal Dust?
No. Group E conductive combustible dust applications should not be assumed suitable for fixtures rated for Groups F or G. Group E is associated with Class II Division 1 treatment when conductive dust is present in hazardous quantities.
Is A Class I Rated Light Also Suitable For A Class II Dust Location?
No. A fixture with a Class I gas or vapor rating is not automatically suitable for a Class II dust location. The exact model should carry the applicable Class II Division 2 marking and dust Group rating.
Can A Lighting Design Help Plan A Class II Division 2 Project?
Yes. Once the hazardous-area classification is documented, a hazardous-area lighting design can show expected fixture quantity, placement, mounting heights, foot-candles, and uniformity. Fixture quantity and layout should consider mounting height, optics, lumens, spacing, obstructions, and required light levels rather than relying on a standard wattage assumption.
