Explosion protected helmet lamp/torch, with eLED, power 23.3 W, neon yellow. Supplied = assembled. Bulb = eLED. Operating life = 8.4 hrs. Luminous flux = 165/130 lumen. Illuminates up to = 232 - 387 m. Power supply = battery operated. Battery = 4x1.5 V AA. Power = 23.3 watt. Protection type = IP67. ATEX zone = 0, 1, 2, 20, 21, 22. Length = 162 mm. Width = 41 mm. Light head diameter = 36 mm. Weight = 0.18 kg. Material = polycarbonate, ABS plastic. Can be attached to all work helmets using helmet mounts. Easy to load battery compartment for fast battery replacement. Safety certificate for use in areas at risk of explosion in zone 0, 1 and 2 for gas/zone 20, 21 and 22 for dust. Focussable light beam (narrow 18°/wide 37°) Large push switch can also be operated with gloves on. Waterproof and dustproof. The helmet lamp is equipped with a front switch and features a high performance LED. The projection optics allow the width of the beam to be varied by turning the lamp head (from a wide beam to a focussed beam) A high power 2 watt LED lasts for thousands of hours and will not break if the lamp is dropped. The unique eLED electronics provide a consistently bright beam for more than 80% of the battery life of the alkaline batteries. The rubber lamp head reduces the dazzle effect and improves the impact resistance. Hydrogen catalyst, battery contacts with polarity indicator and a pressure compensation valve reduce the risk of explosion if batteries leak. Robust, electrically non-conductive, corrosion resistant ABS polycarbonate housing. Includes 4 type AA batteries.
