Streamlight ProTac tactical series flashlights, including the ProTac1L, ProTac 2L, ProTac 1AA and ProTac 2AA, combine compact size and C4 LED technology. All four upgraded lights now feature TEN-TAP programming, which enables users to select among three programs: high/strobe/low (the factory default setting); high only;or low/high. On high, the upgraded lights now feature a range of 70 to 260 lumens and run times of up to three hours. The ProTac 1L and ProTac 2L use one or two 3V CR123A lithium batteries and the ProTac 1AA and ProTac 2AA use one or two AA alkaline batteries. Each light features a C4 LED for extreme brightness.
