The 3AA ProPolymer Dualie is the first intrinsically safe flashlight and floodlight from Streamlight. The dual beams are independently controlled by separate pushbutton switches, so you can choose the right beam for your task. Use the spot beam as a traditional flashlight for navigating in the dark. Switch to the flood beam for up close tasks or to light up an area. Turn on both beams to see what's ahead of you and your feet at the same time, avoiding obstacles as you walk.
