The Wolf LMXE FFA is a next-generation ex-proof luminaire that combines linear general lighting and emergency backup requirements in a single housing for hazardous areas. Offered by IST Safety Ltd, the official distributor of Wolf, this product features "Flexible Field Assembly" (FFA) technology, providing exceptional cabling and placement versatility during on-site installation.
In the event of a power failure, the LMXE FFA automatically switches to battery mode to deliver up to 3 hours of continuous illumination, ensuring peak safety in Zone 1/21 explosive gas and dust atmospheres. With its highly impact-resistant polycarbonate housing, IP67 ingress protection rating, and uniform light distribution, it facilitates the safe evacuation of personnel in the harshest environments, from refineries to chemical processing plants.

What is ATEX and what does exproof mean? The ATEX directive is a set of European Union standards that define the safety requirements for equipment used in hazardous areas with explosive atmospheres. Exproof (Explosion-proof) refers to protection methods designed to prevent explosions by inhibiting the formation of sparks or electrical arcs in environments containing flammable gases, dust, or vapors. To ensure life and property safety in industrial facilities, the use of ATEX-certified exproof devices is a legal requirement.
ATEX Zone coding is a technical classification based on the frequency and duration of the occurrence of an explosive atmosphere in a given area. While the terms Zone 0, 1, and 2 are used for risks originating from gas, vapor, and mist; the codes Zone 20, 21, and 22 are designated for environments containing combustible dust. This classification is a legal standard that determines the required Equipment Protection Level (EPL) for devices. Accurate zone identification both optimizes operational costs and minimizes occupational safety risks.
In addition to ATEX certification, some projects may also require the IECEx Certification System (International Electrotechnical Commission Explosive Atmospheres System) certification. IECEx is an internationally recognized conformity assessment system for equipment intended for use in explosive atmospheres.
While ATEX is a European Union directive and a legal requirement within the European market, IECEx is a globally accepted certification system, widely preferred in regions such as the Middle East, Asia, and Australia.
From a technical perspective, both ATEX and IECEx are based on similar standards (e.g., the EN/IEC 60079 series). However:
Therefore, while ATEX certification may be sufficient for certain projects, international tenders or critical industries such as oil & gas often prefer or require products that are certified to both ATEX and IECEx standards.
The appropriate certification should be determined based on the project location, client requirements, and application area.
