Streamlight Inc. introduced the TLR-7 HL-X, a 1,000-lumen, multi-fuel, rail-mounted light with a longer-reaching beam that provides up to 22,000 candela. The new light gives users the choice of using either a cost-saving SL-B9 USB-C rechargeable battery pack or a 3-volt CR123A lithium battery, depending on availability or user preference.
