The Wolflite® H-251 MK2 is a rechargeable handlamp approved by Baseefa and suitable for use in hazardous Zones 1 and 2. Applications include the petrochemical and offshore industries, fire-fighting, gas and water distribution, wherever a potentially explosive atmosphere may occur.

Product Information


The H-251 MK2 is constructed in highly durable polypropylene co-polymer, designed to withstand the effects of heavy industrial use. The glass lens is scratch and scuff resistant and will not discolour when in contact with chemicals. The entire product has been 'drop' tested for damage and both the outer and inner components proved equally highly resilient. Many unique design features are incorporated in the H-251 MK2 including; an interlock mechanism preventing internal access when the lamp is in use, short circuit protection via a ceramic fuse and a magnetically operated, hermetically sealed Reed Switch to avoid open internal sparking. The rechargeable battery pack is made up of two sealed lead acid cells assembled into a robust casing. This battery pack has a recharge/discharge life of approximately 500 cycles.
The H-251 MK2, has charging contacts on the base of the lamp to enable battery charging 'in situ' using the lamp charger. The H-251 MK2 chargers are available for mains (120/230v) or low voltage (12-32v) input for use in vehicles. All chargers have LEDs which indicate state of charge, a rating plate on the charger explains the sequence of this. The H-251 MK2 conforms with the DOT Class I 'Safety Lamp' specification, Regulation 17 of the SOLAS protocol and has been issued with a Lloyds Register of Shipping Type Approval Certificate. The H-251 MK2 is supplied complete with battery pack, lock key and shoulder lanyard, together with maintenance instructions giving comprehensive details of spares available and guidance for installation.
