The Wolf Markerlite is a compact, high-visibility LED indicator designed specifically for use in hazardous environments where safety and visibility are critical. Certified to both the ATEX directive and IECEx standards, this device is approved for safe operation in potentially explosive atmospheres, including Zone 1 gas (IIC/T4) and Zone 21 dust (IIIB/200°C). Its robust and intrinsically safe design makes it suitable for a wide range of applications in dark or low-visibility conditions, where identifying personnel, marking hazards, or delineating escape routes and equipment is essential.
This self-contained unit is powered by two CR2032 lithium coin cells and utilizes an ultra-bright, 'fitted for life' LED available in white, red, or amber. The LED offers two lighting modes—flashing, with a runtime of up to 65 hours, and static, providing up to 25 hours of continuous output. Its 180° wide-angle beam ensures the light is visible from both the front and sides, and in total darkness, the beam can be seen from over half a mile (0.8 kilometers) away, ensuring that personnel or hazards are clearly identified even at a distance.
Designed for durability and ease of use, the Markerlite features a rugged polycarbonate and thermoplastic elastomer enclosure that is both drop and impact resistant. Its IP67 rating ensures it is completely dust-tight and capable of withstanding immersion in water up to 1 meter deep. A single-handed switch allows for easy activation and mode selection, making the unit highly practical in urgent or difficult conditions. The integrated mounting clip and reusable cable tie slot, along with a grip pad that prevents rotation, provide flexible attachment options to headwear, clothing, site bicycles, or fixed equipment. With a weight of only 23 grams including batteries and a compact form factor less than 37mm in diameter, it is ideal for personal carry without adding bulk.
The Wolf Markerlite is engineered with safety at the forefront, incorporating intrinsic safety protection to ‘ib’ level and certified for Zones 1 and 2 gas groups IIA, IIB, and IIC, as well as Zones 21 and 22 for dust groups IIIA and IIIB. It operates reliably within a wide ambient temperature range of -40°C to +55°C and maintains a maximum surface temperature of 200°C in dust environments. The enclosure is built from tough polycarbonate materials, and the LED light source delivers 4.7 lumens with an expected life of 25,000 hours. The device comes fully ready for deployment with pre-installed batteries, an integrated clip, reusable cable tie, and full operating instructions, offering a dependable and convenient solution for hazardous area safety marking.
