The Streamlight USB HAZ-LO Intrinsically Safe Headlamp is a rechargeable, multi-function, and intrinsically safe headlamp. The headlamp features three lighting modes to cover a variety of tasks: a spotlight for a focused beam; a flood setting for soft area illumination that won’t tire eyes; and a spot/flood combination for maximum light output. On high, the headlamp’s spot beam delivers 190 lm and an 89m beam distance; the flood beam offers 120 lm and over a 19m beam distance. The combined spot/flood setting provides 250 lm with a run-time of seven hours. In spot and flood modes, the run-times are seven and a half hours and 13 hours.
