The Streamlight ProTac 2.0 Rail Mount (SKU 89003) is a high-output rail-mounted rifle light producing 2000 lumens output and 17,700 candela peak beam intensity for a 266 metre beam, with broad spill around a concentrated hotspot and a 250 lumen low mode.
This 89003 configuration is the light-only version: it includes the M-LOK mount, the SL-B50 USB-C rechargeable battery pack and a charging cord, but no remote switch, so it is operated from the tail cap. The body mounts directly to MIL-STD-1913 Picatinny rails, is TEN-TAP programmable, and is built from Type II MIL-spec anodised aluminium rated IP67.
How It Compares
For the same light supplied with a straight momentary remote pressure switch and its mounting hardware, see the Streamlight ProTac 2.0 Rail Mount weapon light system. If you need long throw rather than a balanced beam, the Streamlight ProTac 2.0 Rail Mount HP rifle weapon light focuses the same 2000 lumens into 85,000 candela.
