Streamlight's Stinger LED HP and Stinger DS LED HP rechargeable flashlights provide brightness and versatility with C4 LED technology, three intensity levels, and a popular strobe feature. The two lights provide more than 200 percent more intensity than the Stinger LED and Stinger DS (dual switch) LED, according to the company. The new models also offer long runtimes. At the high level, the lights operate for two continuous hours to the 10-percent output level, 3.75 continuous hours at medium brightness, and 7.25 hours at low brightness. The strobe runs up to 5.5 continuous hours. Both the Stinger LED HP and Stinger DS LED HP are backed by Streamlight's limited lifetime warranty.
