Streamlight Releases ProTac 2.0 – Plethora of Improvements

Streamlight ProTac series is popular for a reason, packing a long list of features and durability into an affordable light. Newly released is the ProTac 2.0, bringing generational improvements to an already excellent light.

Let’s start with the end cap. Streamlight is releasing the Protac 2.0 with their new TEN-TAP end cap which allows the user to program their own operating modes. This would allow you to program what happens when you press the button, high, low, or strobe. This to me is an excellent feature as not all users what a dual pressure switch to activate between high/low or to even have a strobe option. Choose what you want.

As an example, to turn on each lighting mode within the ProTac® HL’s default program:

  • High: Tap and hold; click to lock on; click again for off
  • Strobe: Fast double-tap (within 0.4 seconds) and hold; click to lock on; click again for off
  • Low: Fast triple-tap (within 0.4 seconds per tap) and hold; click to lock on; click again for off

Powering the ProTac 2.0 is Streamlight’s SL-B50 USB-C Rechargeable Battery Pack. This is a Lithium-ion cell with similar dimensions to an 18650 but sports an integrated USB type C charging port, safety circuit to prevent over discharge or overcharge, and a very impressive 4,900mAh capacity. Sliding the collar on the ProTac 2.0 allows access to the charging port to ensure your light is ready to go.

  • Use the SL-B50® battery pack to power the ProTac® 2.0, ProTac® 2.0 Headlamp, and the ProTac® 2.0 Rail Mount
  • 3.6V, 4900mAh, rechargeable at least 500 times
  • Charges in 6 hours using USB-C input

  • 3.26 in (8.28 cm); 3.0 oz (85.0 g)

Finally with the ProTac 2.0 itself. Impressive specifications, long list of features, and a MSRP of $195.00 (street price will most likely be a good bit lower), this could be one of the best EDC lights for the money.
