ATEX & IECEx Certified Fixtures
Certification is not optional in a hazardous area — it defines which fixture may be installed where.
Matching the Ex rating to the zone
- Gas atmospheres: Zone 1 / Zone 2 with ATEX (2014/34/EU) or IECEx, and UL844 / NEC Class I Division 1 or 2 for North America.
- Dust atmospheres: Zone 21 / Zone 22 for combustible dust (grain, flour, carbon, metal powder).
- Every fixture ships with a documented certificate so EPCs and inspectors can verify compliance before energising.
Explosion-Proof High-Bay Lighting
High-clearance hazardous spaces — refineries, bulk terminals, process halls — need high-output fixtures that stay certified at height.
Built for the harsh envelope
Corrosion-resistant enclosures, anti-vibration mounting and sealed optics keep the Ex rating intact under heat, humidity and vibration. Pair with emergency battery-backup for safety egress.
Sized by lux, not watts
We provide a free lux-layout so you hit target illumination uniformly (±5%) across the hazardous zone without over-specifying.

What Is Explosion-Proof Lighting?
Explosion-proof (often called flameproof) lighting is a luminaire built so that any ignition of flammable gas, vapour or dust inside the enclosure cannot escape and ignite the surrounding hazardous atmosphere. The housing contains an internal explosion and tolerates the pressure, while precision flame paths cool hot gases below the auto-ignition temperature before they exit. It is certified by zone and gas/dust group — for European and international projects typically ATEX (2014/34/EU) or IECEx, and for North America UL844 / NEC Class I Division 1 or 2. It is not the same as ordinary 'waterproof' lighting and must never be substituted in a classified area.
ATEX vs IECEx: What Is the Difference?
Both certify equipment for explosive atmospheres, but they differ in scope and acceptance. ATEX is the European legal framework (Directive 2014/34/EU) required for equipment placed on the EU market, with Notified Bodies issuing the certificate. IECEx is the international scheme (based on IEC 60079 standards) that lets a single certificate be recognised across many countries without re-testing. A product can hold both. In practice: specify ATEX for EU projects and IECEx (often alongside local approvals) for global export — we supply fixtures with the correct Ex rating and documentation for your target market.
How to Select Explosion-Proof Lighting for Hazardous Areas
Select in four steps. (1) Identify the hazard: gas or dust, and the Zone (Gas 1/2, Dust 21/22) from your area classification study. (2) Match the certification: ATEX/IECEx with the correct gas group and temperature class (T-rating) for the specific flammable material. (3) Choose the form factor and output for the space — high-bay for high ceilings, linear for aisles — and confirm ingress rating (IP66 is typical in hazardous areas; IP69K only where high-pressure washdown is used). (4) Verify documentation: a valid Ex certificate and markings on the fixture. We map your zone classification to a certified fixture and provide the certificate for inspection.
What certification do explosion-proof lights require?
For European and most international projects, explosion-proof fixtures need ATEX (2014/34/EU) or IECEx certification matched to the hazard zone — Gas Zone 1/2 or Dust Zone 21/22. In North America, look for UL844 / NEC Class I Division 1 or 2. We supply fixtures with the correct Ex rating and a documented certificate so EPCs and inspectors can verify compliance before energising.
What is the difference between IP65 and IP69K for industrial lights?
IP65 resists low-pressure water jets and dust; IP69K (per IEC 60529) survives 100-bar, 80°C high-pressure washdown from any angle. Food, pharma and wash-down plants need IP69K; a standard IP65 fixture fails under routine pressure cleaning within 6–12 months. Specify IP69K wherever hoses or sanitation tunnels are used. In hazardous (explosion-proof) areas, IP66 is the common baseline with the Ex certification doing the safety work.
