The Wolf WAL (Wide Area Luminaire) LinkEx LED system is a next-generation modular ex-proof floodlight designed to safely illuminate extensive sites and large-scale workspaces in hazardous areas. Offered by IST Safety Ltd, the official distributor of Wolf, this system serves as a highly efficient alternative to traditional 250W and 400W halogen floodlights, providing up to 80% energy savings and a powerful output exceeding 6,000 lumens.
The standout feature of the system is the "LinkEx" (daisy-chain) connectivity architecture, which allows multiple units to be interconnected to illuminate vast areas from a single power source. Certified for Zone 1/21, the WAL series features an impact-resistant polycarbonate lens, IP67 ingress protection, and a lightweight aluminum body, ensuring consistent performance in the most demanding industrial environments, from shipyards to refineries and aircraft hangars.
The WAL Area Light is a high-power, portable LED designed for hazardous environments, ideal for safely illuminating large areas with wide, even light coverage. Certified to ATEX and IECEx standards, it is suitable for Zones 1, 2, 21, and 22 potentially explosive atmospheres. The WAL-725 model features 32 LEDs with a 62° beam angle and delivers up to 30,944 lumens. Its marine-grade aluminium housing is rated IP66/IP67 for dust and water resistance, and a full range of mounting accessories ensures flexible installation for both indoor and outdoor use.

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.
