This Flashlight is cETLus, ATEX, and IECEx listed Intrinsically Safe for use in both above and below ground hazardous locations where explosive gases and dusts may be present. The 5418 uses a CREE® LED rated at 200 lumens that works with a deep parabolic reflector to create a 143 meter flashlight beam. The tail switch provides momentary or constant-on functionality. This light meets the requirements of NFPA-1971-8.6 from 3 AA premium batteries (not included). The mount can be attached to either side of the helmet to provide hands-free illumination. Additionally, the user can set the angle of the mount through 140 degrees of adjustment to provide clearance around face shields, goggles or other helmet-mounted equipment.
