The rechargeable Stinger 2020 does not operate like or even look like any other Streamlight duty light. It features a sliding selector switch that allows the user to choose from three different output levels: low, medium, and high. On high it gives the user a 2,000-lumen beam; medium is 850 lumens; low is 100 lumens. The Stinger 2020 has a squared-off look with flat edges that prevent it from rolling. Another interesting aspect of the new Stinger’s design is the notch on the flashlight’s body that makes it really hard for anyone to take away your light.
