Description
Streamlight built the TLR RM 2 for folks who want real reach out of a long gun light without a bulky housing getting in the way. It runs 1,000 lumens through an HPL (High Performance, High Lumen) face cap that focuses the beam into a tight, hot center measuring 22,000 candela, which translates to a usable throw of 297 meters. That combination of punch and distance is what sets it apart from a typical flood-style weapon light. You get a beam that lights up a target across a field while still spilling enough peripheral glow to keep your surroundings visible.
Why the TLR RM 2 Beam Reaches So Far
The magic here is candela, not just lumens. A lot of lights brag about raw brightness but throw a wide, short beam. The TLR RM 2 uses its engineered optic and HPL cap to concentrate that output, so the light actually goes the distance instead of washing out at close range. It runs 1.5 hours on high and up to 3 hours in strobe mode, powered by two included CR123A lithium batteries that hold a shelf life of around ten years.
Built to Take a Beating
The body and face cap are machined from 6000 series aircraft aluminum wearing a Type II Mil-Spec anodized finish, so it shrugs off recoil, weather, and hard handling. It carries an IPX7 waterproof rating, meaning it can sit under a meter of water for half an hour and keep working, and it's rated to run in temperatures from 40 below zero up to 120 degrees. At just under 5 ounces and roughly 5 inches long, it sits low and tight against the rail to keep your rifle sleek and snag-free.
Mounting the TLR RM 2 on Your Rifle
This one attaches to any long gun with a MIL-STD-1913 Picatinny rail. The included key kit lets it fit a broad range of platforms, and the one-handed snap-on and tighten interface keeps your fingers well clear of the muzzle during install. The ergonomic tail switch handles momentary and constant-on with a safe-off feature that twists the bezel to lock out accidental activation and preserve battery life. It's also wired to accept a remote pressure switch if you decide to add one down the road.

Frequently Asked Questions
Does the TLR RM 2 come with a remote pressure switch?
No, this particular version (part number 69451) is the light-only model, so it ships with the light, a key kit, and two CR123A batteries. If you want the remote pressure switch included in the box along with mounting clips, that's the 69450 system version. The good news is this light is wired to accept a remote switch, so you can add one later if you change your mind.
What kind of firearms will the TLR RM 2 fit?
It's designed to mount on long guns that have a MIL-STD-1913 Picatinny rail, so think AR-platform rifles, shotguns, and similar setups. The included key kit helps it lock onto a broad range of rail dimensions securely. The one-handed clamp system tightens without tools and keeps your hands behind the muzzle during install.
How is the TLR RM 2 different from a standard weapon light?
The big difference is throw. While plenty of lights push 1,000 lumens, the TLR RM 2 uses an HPL face cap and focused optic to generate 22,000 candela and reach out to 297 meters. That means it puts more usable light on a distant target instead of just flooding the area right in front of you.
Is the TLR RM 2 waterproof and how long does the battery last?
It carries an IPX7 rating, so it can handle full submersion in a meter of water for 30 minutes and keep running. On a fresh set of the two included CR123A batteries you'll get about 1.5 hours of continuous high output, or up to 3 hours in strobe mode. The lithium cells also have a roughly ten-year shelf life, so it's ready when you need it.
