The Bayco Nightstick Safety Rated Dual Light is designed for use in hazardous workplace environments. It is cETLus Listed Intrinsically Safe for use in Class I, II, III, Div 1, Groups A, B, C, D, E, F & G hazardous locations. With its CREE LED rated at 80 lumens and high efficiency deep reflector the Flashlight beam on this light has an effective range of 95 meters (over 300 feet). Additionally, built into the handle of this light is an 80 lumen Floodlight. Unlike the flashlight beam, the light coming out of the floodlight does not have a reflector so the light spreads out in a wide, even, unfocused pattern of light...perfect for lighting up things that are close by. Its waterproof design in combination with its impact and chemical resistant engineered polymer housing, make this tough little light, one of the best values around. The flashlight is actuated by means of the top body switch which provides both momentary and constant-on functionality. The floodlight is operated using the bottom button. Additionally, both lights can be turned on at the same time for even more versatile lighting options. Now you have a light for distance and one for close up work. That's the idea behind Dual Light. Running on 3 AA batteries (not included), this Safety Rated Dual Light will run in Flashlight Mode for 14.5 hours, in Floodlight Mode for 14.5 hours and in Dual Light Mode for 7 hours. It also includes a built-in heavy duty pocket clip and a removable lanyard.
