The RHL-4 Rescue Headlamp uses a patented lens system to vary the beam spread from a very narrow 5° to an extra wide 40° beam angle. Quickly adjust the headlamp by pulling the lamp head forward for a narrow beam, or pushing back for illumination. The RHL-4 uses a CREE Q5 high brightness LED producing 225 lumens of bright white light. The ON/OFF switch is conveniently mounted at the top of the lamp head. Three modes of operation are available at the touch of the switch; high, low and strobe. The RHL-4 Rescue Headlamp has a long high beam burn time of up to 3 hours. Three AAA batteries nest in a battery holder behind the lamp head. The hinged lamp head can be tilted down 90° from horizontal, putting the light where you need it. The RHL-4 Rescue is weather resistant and effective up to 300 yards.
