Streamlight Announces 2,000 Lumen ProTac 2.0 Rail Mount

Streamlight’s line of weapon lights just got a little brighter with the introduction of the ProTac 2.0 Rail Mount. Boasting 2,000 lumens and a rechargeable battery, the 2.0 breathes new life into an already capable package. TFB covered the handheld version of this light earlier, but this is The Firearm Blog, so the gun-mounted light deserves some coverage as well.

More Lights @ TFB:

The ProTac series has a reputation as one of the better affordable weapon lights. They are not cutting-edge performance but are generally seen as a good balance of price and performance. The ProTac 2.0 narrows the gap to the much more expensive competitors.

Streamlight swapped the CR123A batteries from the older ProTacs for a proprietary SL-B50 rechargeable unit. It charges through a USB-C connector without removing the battery from the light body. That battery enables the ProTac 2.0 to push 2,000 lumens (17,700 candela) on high mode with a listed runtime of 2.5 hours. TEN-TAP programming allows use in strobe or low modes as well.
The battery can be recharged without removing it from the light.
The Rail Mount 2.0 includes a Picatinny rail mount (as suggested by the name). It also has a redesigned tail cap and remote pressure switch. On the old models, installing the remote switch removed the activation switch from the light body. The new unit is sort of similar to a SureFire tail cap, with both a plug for the remote switch and a button on the tail cap for momentary and constant-on modes. The remote switch is strictly for momentary activation.
The new tail cap has a button for momentary and constant light activation, as well as a port that accepts a remote pressure pad.
ProTac 2.0 models are available at retailers now with a street price of around $175.
