The Streamlight ProTac 2.0 Rail Mount Weapon Light is a high-output rifle weapon light with a balanced beam — 2000 lumens and 17,700 candela giving broad spill with a concentrated hotspot for close-quarters work and mid-range target ID (266 m), plus a 250-lumen low mode.
This 89003 configuration is the light-only version: it includes the M-LOK mount, SL-B50 USB-C rechargeable battery pack and charging cord, but no remote switch (tailcap activation). The light body mounts directly to MIL-STD-1913 (Picatinny) rails. TEN-TAP programmable, Type II MIL-spec anodised aluminium, IP67.
