Streamlight's High Lumen (HL) flashlight models use state-of-the-art C4 LED technology to provide law enforcement, tactical, outdoor and other users with extreme brightness, delivering up to 640 lumens. The models include the rechargeable Stinger LED HL, Stinger DS LED HL and Strion LED HL, as well as two gun-mounted models, the TLR-1 HL, and the TLR-2 HL. These models provide similar or slightly higher lumens (with at least 500 lumens) than those in the traditional line but deliver superior long-range lighting because of the increased candela.
