Product Information
The Wolflite H-251 is a rechargeable Handlamp approved by BASEEFA and suitable for use in
hazardous zones 1 and 2. Since its launch in 1980 the Wolflite has found a place as the market
leader in hazardous area portable lighting equipment. Applications include the Petrochemical and
Offshore industries, Fire-fighting, Gas and Water distribution, in short wherever a potentially
explosive atmosphere may occur.
The Wolflite 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 Handlamp, 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 Lamp chargers are available for mains (120/230v)
input or low voltage (12-32v) input for use in vehicles. All chargers have Light Emitting Diodes
which indicate state of charge, a rating plate on the charger explains the sequence of this. The
Wolflite H-251 Handlamps conform with the DOT Class I 'Safety Lamp' specification, Regulation 17 of
the SOLAS protocol and have been issued with a Lloyds Register of Shipping Type Approval
Certificate. The Wolflite H-251 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.
