Product Description The PolyStinger LED HAZ-LO was developed for hazardous locations, atmospheres and environments including petro-chem, utility, and other heavy industrial applications. This intrinsically safe rechargeable flashlight offers microprocessor controlled intensity modes, long running moonlight mode and the latest in power LED technology. The combination of rechargeable batteries and the LED results in one of the lowest operating costs of any intrinsically safe flashlight made. Light has a 50,000 hour lifetime. The case is made with super-tough, non-conductive nylon polymer and features a camshaft style grip. The lens is made using unbreakable polycarbonate with scratch-resistant coating. Deep-dish parabolic reflector produces a tight beam with optimum peripheral illumination to aid in navigation. Moonlight mode: 120 c and ela peak beam intensity and 1.3 lumens measured system output. Multi-function, head mounted electronic push-button on/off is switch designed for an extremely long life. tested at 1 million actuations. In moonlight mode, the PolyStinger LED HAZ-LO will last 20 days of continuous runtime.
