Streamlight ProTac 2.0

The current top of the ProTac line, built around Streamlight's SL-B50 battery pack, a protected 21700-format cell with its own USB-C port that is the only cell the light accepts. Output is 2,000 lumens at 17,300 candela for 262 metres, two and a half hours on high, from a 6.1-inch body that weighs 8.25 ounces. The tail switch runs TEN-TAP, which chooses between high-strobe-low, high only, or low-medium-high. IP67, no LED or CRI named, and a dealer's list price stands in for the MSRP Streamlight does not publish.
