Explosion Proof Flood & High Bay Lighting (Class 1 Div 1 & Div 2 Certified)

Maes Lighting delivers rugged, certified explosion proof flood and high bay LED fixtures for hazardous industrial environments. Built to meet UL844, ATEX, and IECEx standards, our flood and high bay lights ensure reliable, high-output illumination in oil & gas, chemical, power, and marine facilities where safety is mission-critical.

When to Choose Explosion Proof Flood Lights and High Bay LEDs, C1D1, C1D2

Flood and high bay designs are selected when facilities need broad, high-output illumination for large hazardous environments where linear fixtures cannot cover efficiently. They are ideal for:

  • Outdoor refineries and yards needing wide coverage and glare-free lighting.

  • Hazardous warehouses and power plants requiring high mounting heights.

  • Skids, process units, and confined hazardous areas where compact C1D1 flood lights excel.

Key benefits: reliable operation in explosive atmospheres, flexible mounting (wall, ceiling, pole, pendant), wide lumen ranges, and compliance with Class/Division standards.

Explosion Proof Flood & High Bay Lighting FAQs

What’s the difference between C1D1 and C1D2 flood/high bay lights?

C1D1 fixtures (like EX-C and EXD) are required where explosive gases or vapors are present during normal operation. C1D2 (like EXA) covers areas where hazardous substances are normally contained and only present under abnormal conditions.

Can these fixtures replace legacy HID floodlights?

Yes, all EXA, EX-C, and EXD models are LED replacements for HID, offering longer lifespans, instant start, and up to 75% energy savings.

Do I need marine-rated certification for offshore use?

Yes, if installing near saltwater or marine environments. EXA, EX-C, and EXD all carry UL 1598A Marine ratings for offshore and dockside use.

What mounting options are available?

Models support wall, ceiling, pole, or pendant mounts depending on wattage and application. Always confirm clearance and conduit requirements.

What warranty is included?

Most models include a 5-year manufacturer warranty, with L70 lifespans designed for long operation in hazardous conditions.
