For industrial and offshore facilities, selecting the correct explosion-proof lighting is critical for safety, compliance, and operational reliability. The AGC Lighting HA06 LED Linear Luminaire is certified for both Zone 1 and Zone 2 hazardous locations, supporting gas and dust environments with IECEx and ATEX approvals.
This article breaks down the key differences, certifications, applications, and specifications of the HA06 Zone 1 and HA06 Zone 2 versions to help you choose the right model for your project.
Core Safety Concept: Zone 1 vs. Zone 2
First, it is essential to understand the hazardous area classification:
- Zone 1: An atmosphere where a flammable gas–air mixture is likely to occur during normal operation.
- Zone 2: An atmosphere where a flammable gas–air mixture is not likely to occur in normal operation, or only exists for a short time if it does occur.
The HA06 Series uses different Ex protection types to match these risk levels while maintaining strong durability, IP66, and IK08 performance.
1. Certification & Explosion Protection Comparison
The biggest structural and compliance difference lies in the Ex marking.
HA06 – Zone 1 (High-Risk Gas Zones)
IECEx: Ex eb mb IIC T5/T4 Gb; Ex tb IIIC T95°C/T100°C Db
ATEX: II 2G Ex eb mb IIC T5/T4 Gb; II 2D Ex tb IIIC T95°C/T100°C Db
Protection Type: Enhanced safety + encapsulation (Ex eb, mb)
Suitable For: Zone 1, Zone 2, Zone 21, Zone 22
Temperature Class: T5 (100°C), T4 (135°C)
Cert Level: Full 2G / 2D (high-level certification)
HA06 – Zone 2 (Lower-Risk Gas Zones)
IECEx: Ex nR IIC T6/T5 Gc; Ex tb IIIC T80°C/T95°C Db
ATEX: II 3G Ex nR IIC T6/T5 Gc; II 2D Ex tb IIIC T80°C/T95°C Db
Protection Type: Restricted breathing (Ex nR)
Suitable For: Zone 2, Zone 21, Zone 22
Temperature Class: T6 (80°C), T5 (100°C)
Cert Level: 3G / 2D (standard for Zone 2)
Key Takeaway:
HA06 Zone 1 can replace Zone 2 (higher level can cover lower level).
HA06 Zone 2 CANNOT be used in Zone 1.
2. Electrical & Thermal Performance
Both versions support wide voltage and strong surge protection, but thermal limits differ due to the certification structure.
Common Specifications
- IP66 / IK08 / C4 corrosion resistance
- LED efficacy: up to 160 lm/W
- Warranty: 5 years
- Dimming: 0–10V
- Clear Polycarbonate/Diffused Polycarbonate options
Wattage Difference:
- HA06 Zone 1: 2FT: 40W/50W; 4FT: 50W/75W/100W), can flexible wattage you wanted in 20W-100W.
- HA06 Zone 2: 2FT: 20W/30W/40W/50W; 4FT: 60W/70W/80W/100W)
Input voltage Difference:
- HA06 Zone 1: 120–277Vac;152-300Vdc
- HA06 Zone 2: 120-277Vac, 18- 48Vdc, 24-48Vac, 277-480Vac
Functions Difference:
- HA06 Zone 1: Only DM (Dimmable) is supported, no EM function
- HA06 Zone 2: Emergency Battery; Emergency Battery + Dimmable
Working Temperature Difference
HA06 Zone 1:
- 2FT: −40°C to +50°C / +60°C
- 4FT: −40°C to +45°C up to +65°C (depends on power)
HA06 Zone 2:
- −40°C to +40°C / +55°C
- Lower surface temperature (T6: 80°C) for safer heat-sensitive environments
Beam Distribution Difference:
HA06 Zone 1:
HA06 Zone 2:
3. Mechanical Design & Installation
Both versions share the same GRP housing, pc cover options, mounting styles, and dimensions.
Shared Mounting Options
- Ceiling Mount
- Trunnion (Yoke) Mount
- Pendant Mount
- Loop Mount
- Hoop Mount
- Recessed Mount
Housing & Durability
- Material: Fiberglass-reinforced polycarbonate (GRP)
- No powder coating (anti-corrosion)
- Clear or diffused PC covers
- Cable entries: M20, M25, M32, 1/2NPT, 3/4NPT, 1NPT
Mechanical Difference: None.
Housing, dimensions, weight, and accessories are fully compatible.
4. Recommended Applications
HA06 Zone 1 – High-Risk Facilities
- Oil & gas refineries
- Onshore & offshore drilling platforms
- Chemical plants with continuous explosive risk
- Gas pipeline pumping stations
- Facilities with persistent flammable vapors
HA06 Zone 2 – Standard Industrial Hazardous Areas
- Chemical storage areas
- Pulp & paper mills
- Paint spray booths
- Grain processing & coal handling
- Wastewater treatment
- Power generation plants
- General manufacturing with occasional hazardous fumes
5. Which One Should You Choose?
Choose HA06 Zone 1 if:
- Your project is rated Zone 1
- You need a full IECEx / ATEX 2G certification
- You want one light type to cover both Zone 1 and Zone 2 areas
- High reliability and safety are top priorities
Choose HA06 Zone 2 if:
- Your facility is Zone 2 only
- You need a cost-effective certified solution
- You require a lower surface temperature (T6)
- You need a robust linear light for non-continuous hazardous atmospheres
Final Summary
The HA06 Series provides a complete, flexible solution for both Zone 1 and Zone 2 hazardous locations.
Zone 1: Higher protection, wider compatibility, full 2G certification.
Zone 2: Optimized for lower-risk areas, cost-effective, T6 temperature class.
Both deliver industrial-grade performance: IP66, IK08, C4 corrosion resistance, long lifespan, and multiple mounting options.
