New Wolf Markerlite highlights personnel and hazards in explosive atmospheres

04 August 2015

Wolf Safety, the world’s leading manufacturer of hazardous area portable and temporary lighting, launches the Wolf Markerlite, a self-contained high visibility LED visual warning indicator, to clearly highlight the position of personnel and hazards and prevent accidents in dark and reduced visibility hazardous area environments.

Ideal for use as personal identification on protective headwear, clothing and site bicycles and marking escape route, exit and equipment, the Wolf Markerlite is CE marked to the ATEX Directive and IECEx certified for safe use in potentially explosive zone 1 (IIC/T4) gas and zone 21 (IIIB/200°C) dust atmospheres as encountered in oil, gas and petrochemical, industrial, marine, defence, utilities and emergency services sectors.

Two replaceable primary coin cells power an ultra bright 'fitted for life' LED light, available in three colours including white, red or amber, with switchable flashing or static functions, giving long lasting light output durations of up to 65 hours and 25 hours respectively.  Delivering an excellent wide angle beam of 180° light, the Markerlite is highly visible, cutting through darkness, and can be seen over 0.5 miles / 0.8 kilometres away in clear conditions.  

Alex Jackson, Managing Director at Wolf Safety comments "The Markerlite can be securely fixed and left in position for extended periods of time to continuously highlight dangers and obstacles to avoid and minimise the risk of injuries and accidents - with versatile fixing options - it easily mounts on a headband strap or attaches to any pipe or bar using a cable tie, which is supplied, and a grip pad stops rotation. It really can be positioned almost anywhere in a hazardous area."

He adds "Equally  its small size and weight, less than 37mm in diameter and 23 grams with batteries, makes it compact, self-contained and lightweight, ideal for carrying on your person or attire."

Built for longevity and total reliability, the Markerlite has robust single handed switching for operation (on/off) and function (static/flashing) selection making it easy to activate by simply applying pressure to the lens, plus has drop and impact resistant polycarbonate enclosure and lens and is IP67 dust tight and protected against the effects of immersion up to 1m under water.

The Markerlite is supplied ready to use with integrated clip, re-usable cable tie, batteries and instructions. See detailed product specification at
