The H-251A Wolflite is ideal for use as a general purpose safety lamp for inspection and work tasks in explosive atmospheres. Rechargeable battery operation offers a convenient and cost-effective solution for Ex applications where a handlamp is frequently required for long periods.CE marking of the H-251A Wolfliteis in compliance with the 94/9/EC ‘Explosive Atmospheres’ (ATEX) Directive and the EMC Directive. BASEEFA approval is to the verylatest European ‘EN’ standards for use in potentially explosiveatmospheres. The H-251A also has both a Lloyd’s and an MCA Type Approval for use in potentiallyexplosive atmospheres in marineapplications.The H-251A Wolflite Handlampoffers the same extreme robustnessand reliability for use in harshenvironments found with all Wolflite Handlamps. The scratch and impact resistant lens is made from 6mm toughened glass. The handlampbody and lens ring is moulded in ahighly resilient thermoplastic material able to withstand the drop and impact expected from heavy industrial use, even at sub-zerotemperatures. Additionally thematerial is electrostatic non- hazardous, ensuring there is no risk of a dangerous build up of static charges. The lamp enclosureis sealed to IP66, preventing theingress of dust and sealing against water in all conditions except submersion. The outstanding light output isachieved with the use of a high output, high efficiency long life halogen bulb, focused within a 100mm diameter parabolicreflector giving the user an extremely well defined beam of intense white light. The battery pack, rechargedinternally within the H-251A Handlamp, uses the same highly reliable sealed lead acid system as all rechargeable Wolflite Handlamps, but is enhanced with electronic protection and controls. The battery is rendered intrinsically safe by the use of a fast switching short-circuit protection circuit. A low voltage cut-off feature automatically switches the lamp off when all useful battery capacity has been used, protecting the battery from damage through deepdischarge. Power-failure mode allows the handlamp to be used as an escape light, automatically illuminating if power to the charger is interrupted.The H-251A is recharged in thestandard Wolflite Lamp chargers, the C-251HV mains charger and the C-251LV vehicle charger.The H-251A is supplied with aconvenient removable shoulder strap.
