Product Information

ZONES: 1, 2, 21 AND 22

The Handlamp offers extreme robustness and reliability in harsh environments; the scratch and impact resistant lens is made from 6mm toughened glass and the body and lens ring are moulded in a highly resilient thermoplastic material to withstand drop and impact expected from heavy industrial use, even at sub-zero temperatures. The material is electrostatic non-hazardous, ensuring there is no risk of a dangerous build up of static charges and the enclosure is sealed to IP66, preventing the ingress of dust and sealing against water, except submersion.

H-251ALED's outstanding light output is achieved from an LED light source giving as much as 50% more light and a threefold increase in duration over many handlamps with halogen bulbs. It is focused within a 100mm diameter parabolic reflector giving the user an extremely well defined beam of intense white light.

The battery pack is a highly reliable sealed lead acid system, enhanced with electronic protection and control, and 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 deep discharge.

The emergency illumination function illuminates the handlamp if power to the charger is cut.
