Streamlight Inc. has introduced new models of its popular Strion lights with innovative Dual Switch (DS) technology: the Strion DS, the Strion DS HL (High Lumen), and the Strion DS HPL (High Performance, High Lumen). Each of the rechargeable lights now offers two independent, easy-to-locate switches for added user flexibility. The ultra-compact flashlights provide both a head-mounted, push-button switch and a second, multi-function push-button tactical tail switch for full-feature control, independent of the other switch. All three models, available in different configurations,  feature the latest in C4 LED technology, provide three microprocessor-controlled variable intensity modes and a strobe feature, and feature a Ten-Tap programmable switch.
