The Streamlight ProTac 2.0 Rail Mount weapon light system (SKU 89009) is a high-output rail-mounted rifle light producing 2000 lumens output and 17,700 candela peak beam intensity for a 266 metre beam — broad spill around a concentrated hotspot — with a 250 lumen low mode.
The 89009 package is the full system: it ships with a straight momentary remote pressure switch, an M-LOK mount and mounting hardware alongside the SL-B50 USB-C rechargeable battery pack, so it can be run from the tail cap or the pressure pad. TEN-TAP programming sets the mode order. The light mounts directly to MIL-STD-1913 Picatinny rails, in Type II MIL-spec anodised aluminium rated IP67 (IPX4 with the remote plugged in).
How it compares
Without the remote switch and hardware, the same light is the Streamlight ProTac 2.0 Rail Mount rifle weapon light, light-only. For a far tighter long-throw beam see the Streamlight ProTac 2.0 Rail Mount HP rifle weapon light with remote switch at 85,000 candela, and for a handheld version of the same platform the Streamlight ProTac 2.0 handheld tactical flashlight.

- General-purpose rifle and carbine illumination where spill matters as much as reach
- Civilian Service Rifle, straight-pull and 3-Gun
