Most Helpful Positive Review One very bright light!
Streamlight knocked it out of the park with this one. Super bright rated at 2000 lumens. Coming with the 45 degree rail mount allowed me to mount it on the side nice and tight to the rail. It comes with everything pictured and worked perfectly right out of the box. Only thing is the touch pad is momentary only. On and off is still controlled by the rear cap switch which can be used when the touch pad is installed.

Brightness!

by MSG RET, Verified Owner from AZ, United States Written on September 14, 2025
Slightly larger than I expected. Extremely bright. Disappointed with the pressure pad. The pad is longer than needed, and doesn't have a permanent on mode. Six hours required for full battery charge.
Pros:
  • Brighness
Cons:
  • pressure pad modes
  • six hour charging
Best Used for:
  • Dark environments
  • CQB blinding

Incorrectly sized hardware.

by Johnson, Verified Owner from TX, United States Written on September 7, 2025
The replacement screws for the m-lock mount do not fit in the flashlight. I bought new screws of the same size which did fit. The m-lock mount also did not have the correct depth to fit my handguard, and because I bought cheap screws - they ended up stripping and now I have to drill out the screw to get the m-lock mount off. I feel like there was little to no quality control on this item.

Streamlight 2.0 hp

by M, Verified Owner from NE, United States Written on June 13, 2025
Works well, tested at night to 200 plus yards and could see a coyote through my 3x spitfire. Mounted well to my handrail with included mounts. Pressure switch had to mount to top picatinny rail due to aftermarket piccatinny rail I mounted to side was slightly larger. You wont be disappointed in this new version of streamlight 2.0 hp. 85,000 candella!!!!

Pros:

  • Value & Quality
  • Easy to instal, rock solid lock up
Cons:
  • None
Best Used for:
  • Home defense
