Rechargeable EX safety handlamp with 80 lm, IP54 protection and 4–5 hours runtime suitable for Zone 1 and 2 applications. Read more
The Wolf H‑251MK2 is a rechargeable safety handlamp designed for reliable use in potentially hazardous Zone 1 and Zone 2 environments. It utilises a krypton filled filament bulb producing 80 lm for focused illumination during inspection and operational tasks. The enclosure is made of durable polypropylene engineered to withstand harsh industrial conditions. The lamp carries an EEx e s II T3 classification enabling safe operation in gas groups IIA, IIB and IIC. Runtime ranges from 4 to 5 hours thanks to a sealed lead acid battery designed for up to 500 charge cycles. A 6 mm toughened glass lens ensures optical stability and impact resistance. The IP54 ingress protection rating safeguards the lamp in dusty and moist conditions. Single handed operation is supported by a large switch suitable for gloved use. The anti roll foot and supplied shoulder strap improve practicality in field tasks.
