What is the difference between the Streamlight Stinger and Polystinger flashlights?
What is the difference between the Streamlight Stinger and Polystinger flashlights? Particularly the DS versions?
There are actually two versions of the Stinger and Polystinger. The original versions use bulbs, and the newer versions use LEDs. There are four variations: Stinger LED, Stinger DS LED, PolyStinger LED, Polystinger DS LED. The DS stands for Dual-Switch. This means that there is both a switch on top of the flashlight and on the tail cap. The Stinger LED and PolyStinger LED just have a switch on the top of the light, not one of the tail cap. All of the Stinger series lights, whether they are LED or bulbs, use the same charger holders and cords, so you can reuse them between lights. These Stinger lights also use the same rechargeable battery stick. As far as the technical difference, here’s some more detail:
Polystinger: 7.4″ long, 8.7 oz, 125 lumens
Polystinger LED: 8″ long, 11.5 oz, 185 lumens
Polystinger DS LED: 8.64″ long, 11.9 oz, 185 lumens
Stinger: 7.38″ long, 10 oz, 125 lumens
Stinger LED: 8.4″ long, 12.4 oz, 160 lumens
Stinger DS LED: 8.85″ long, 12.8 oz, 160 lumens
The Polystinger lights are also made from a nylon polymer, and the Stinger and Stinger LED are made from aircraft aluminum. There is also a new series of lights that recently came out, which are the Stinger LED HP and the Stinger DS LED HP. These are even brighter than the Stinger LED and PolyStinger LED and are offered in both a single and dual switch.
