This explosion proof LED lighting lineup covers Class I Division 1 lighting and Class I Division 2 lighting across multiple form factors, including linear fixtures, flood and high bay styles, portable work lights, and exit and emergency units for code compliance and safer operations.

UL844 listings across model families covering Class I, Class II, and Class III hazardous ratings, IP66 sealing, plus NEMA 4X and IK10 options where specified, ATEX and IECEx options, including a portable unit listed for Zone 0, UL 1598A Marine rated linear fixtures for wet and offshore use cases, Explosion proof exit and emergency lighting with UL924 and 3-hour backup options, 5-year warranty is listed on select families, including IR1, EX-ES03, FYS/FYD, and FFS/FFD

When to Choose Explosion Proof LED Lighting for Class I Div 1, Div 2, and Class II Dust Areas

Use explosion proof lights when your area classification requires hazardous location fixtures, for example Class I gases or vapors, and Class II combustible dust. Selection starts with the rating, then the form factor: linear fixtures for aisles, corridors, and process runs, flood and high bay styles for yards and high ceilings, and dedicated exit and emergency lighting for egress. If you need temporary lighting for maintenance, a certified portable work light can reduce downtime while staying compliant.

  • Class I Division 1 lighting: choose families that list C1D1 coverage (EXI, IR4, EX-C, EXD, EX-ES03, EX-MV01)

  • Class I Division 2 lighting: fit for areas where hazards are normally confined (IR1, IR3, IR7, EXH, EXA, plus many multi-rated families)

  • Class II hazardous location lighting (dust): choose C2D1-focused options where dust is primary (EXH, plus multi-rated families that list C2D1)

  • Wet, marine, offshore: prioritize UL 1598A Marine rated linear fixtures, and sealed IP-rated housings where specified

  • Wide-area coverage: flood and high bay families with selectable beam optics and multiple mounting styles

  • Egress and code: UL924 exit and emergency models with listed backup duration

  • Maintenance and confined spaces: certified portable work light options

Explosion Proof LED Lighting FAQs for Hazardous Locations

What is explosion proof LED lighting for hazardous location areas?

Explosion proof LED lighting refers to fixtures listed for hazardous locations where ignitable gases, vapors, or combustible dust may be present. In this lineup, UL844 appears across multiple families, with models covering Class I Division 1 and Class I Division 2, plus Class II dust ratings and Class III where specified. Selection should be based on your area classification, then matched to the right form factor, linear, flood/high bay, portable, or exit and emergency, for the installation.

Which models support Class I Division 1 lighting and UL844 explosion proof listings?

For Class I Division 1 lighting, the document lists C1D1 coverage on several families, including EXI (linear), IR4 (linear), EX-C (flood), EXD (flood/high bay), EX-ES03 (exit and emergency), and EX-MV01 (portable work light). Each should still be matched to the exact groups and any additional Class II or Class III needs listed for your site. Share your classification and install details, and we can narrow the best-fit family quickly.

How do I choose Class I Division 2 lighting vs Class II hazardous location lighting for dust?

Class I Division 2 lighting is typically used where gases or vapors are handled but normally confined, and several linear and flood options in the document target that use case (IR1, IR3, IR7, EXA, plus multi-rated families). For dust-heavy operations, prioritize Class II ratings, and if dust is the primary hazard, the EXH family is positioned specifically for Class 2 Division 1 dust while also listing C1D2 coverage. Start with your dust versus gas exposure, then match output and mounting.

Do you offer explosion proof linear LED fixtures for wet, marine, and offshore environments?

Yes, the document lists multiple linear families with marine and wet-environment suitability. IR1 is described for wet locations and marine environments and lists UL 1598A Marine, IR3 lists UL 1598A Marine for offshore or wet environments, and IR4 includes UL 1598A Marine alongside its hazardous ratings. For projects that also prioritize sealed ingress protection and impact resistance, EXI lists IP66 and IK10 and is described with a marine-ready enclosure. Provide your environment details, and we will align rating and construction.

What optics and mounting options are available for hazardous location LED flood lights?

If you need area coverage and controlled beam spreads, the flood and high bay families list multiple optics and mounting choices. EXA and EX-C both list 40°, 60°, 90°, and 120° beam options with mounting options such as wall, ceiling, pole, or pendant depending on family. EXD also lists the same beam options and includes lens choices (flat or spherical glass) with bracket mounting options. Share target coverage and mounting constraints so we can recommend the right optic and bracket.

Do you have portable explosion proof LED work lights for maintenance and confined spaces?

The document includes a portable option, EX-MV01, designed for temporary job sites and confined work. It lists hazardous approvals including UL844 Class I Div 1 and Div 2 and an ATEX Zone 0 marking, plus IP66 protection. Performance details include a high mode listed at 1,600 lumens, a low mode listed at 500 lumens or higher, and runtimes listed up to 8 hours (high) and 20 hours (low) on a 6.4Ah battery. For quoting, share your runtime needs and charging access.

Is there UL924 explosion proof exit and emergency lighting for Class I Division 1 egress routes?

Yes, the EX-ES03 family is listed with UL844 and UL924 and is positioned for hazardous egress use. The document includes variants for emergency-only, exit-only, and a combo configuration, with a 3-hour backup duration listed. It also lists 2 × 5W emergency heads, a 3 to 5W exit legend for exit-capable variants, red or green letters with directional arrows, and NEMA 4X / IP66 / IK10 protection. Provide your mounting location and legend needs, and we will specify the right configuration.

What input voltage ranges are offered for explosion proof LED lighting on this page?

Several families list wide voltage ranges suitable for facility standards. EXI, EXH, and EX-C list 100 to 277 V and 200 to 480 V options. FYS/FYD and FFS/FFD list dual input voltage ranges of 100 to 277 VAC and 200 to 480 VAC. Linear families IR3, IR4, and IR7 list 120 to 277 V AC in their ordering tables. EX-ES03 lists 100 to 277 VAC, and its combo variant also lists a 12 to 48 VDC option. Share your site voltage and we will match the right driver option.

Which models include emergency operation or backup capability?

Emergency capability appears in multiple parts of the lineup. IR3 lists optional emergency versions, and IR4 lists an emergency egress option in selected configurations. EX-ES03 is an exit and emergency family with a 3-hour backup duration listed, depending on variant. For longer-duration emergency operation on general luminaires, FYS/FYD and FFS/FFD list 90-minute emergency operation. If you tell us whether you need egress signage, task-light backup, or both, we can recommend the best-fit family and configuration.
