Description
The Streamlight TLR RM 1 HL-X is built for long guns that need serious throw. Running the included SL-B9 rechargeable battery pack, it puts out 1,000 lumens and 22,000 candela with a beam that reaches out to 297 meters, so identifying something at the far end of a field, alley, or hallway is no problem. Drop in a CR123A instead and you still get 500 lumens and 210 meters of reach with a run time that stretches to about 90 minutes. That multi-fuel setup is the whole point here: charge the SL-B9 over USB-C when you have the time, or keep a lithium cell on hand so you're never caught dark.
What Sets the TLR RM 1 HL-X Apart
The optic on this one is tuned for candela over spread, meaning a tighter, more concentrated hot center that carries downrange rather than washing out up close. It's a smart pick for anyone who wants their weapon light to do real work past bad-breath distance. The body is machined from 6000 series aircraft aluminum with a Type II Mil-Spec anodized finish, the lens is tempered borofloat glass, and the whole thing carries an IPX7 rating, so a dunk in the rain or a creek isn't going to end its day.
Switching and Mounting the TLR RM 1 HL-X
You get two independent ways to run it. The ergonomic push-button switch on the light works on its own, and the remote pressure switch exits at a 90-degree angle so the wire routes cleanly and doesn't eat up rail space. That flexibility means you can mount at 12, 9, or 3 o'clock, or offset, and still reach the controls with your support hand. A safe-off lockout keeps it from turning on by accident and draining the battery in your bag or safe.
This is the Light Only model, so it ships with the light, a key kit for fitting different rail setups, the SL-B9 battery pack, and a USB-C charging cord. It clamps to any MIL-STD-1913 Picatinny rail, and if you're running an M-LOK handguard, Streamlight offers a dedicated M-LOK mount separately.

Frequently Asked Questions
Does the TLR RM 1 HL-X come with the remote pressure switch?
No. This is the Light Only model (69484), so it includes the light, key kit, SL-B9 battery pack, and USB-C cord, but not the remote pressure switch. If you want the pressure switch and mounting clips in the box, look at the System version instead, or add a compatible Streamlight remote switch separately.
What batteries can I run in the TLR RM 1 HL-X?
It's multi-fuel, so you can run the included SL-B9 rechargeable pack that charges over USB-C, or drop in a single CR123A lithium cell. The SL-B9 gets you the full 1,000 lumens and 22,000 candela, while a CR123A runs 500 lumens with a longer overall run time. Keeping a spare CR123A around is a good idea if you don't want to stop and recharge.
Will this fit an M-LOK handguard?
The TLR RM 1 HL-X clamps directly to MIL-STD-1913 Picatinny rails out of the box. For M-LOK setups, Streamlight makes a dedicated TLR M-LOK mount (part 88301) that's sold separately. That lets you run it clean and low on an M-LOK rail without adding a bulky adapter.
How far will the beam actually reach?
With the SL-B9 pack, the beam reaches out to 297 meters, which is right around 970 feet. The optic is tuned for candela, so you get a tighter, concentrated hot center that carries downrange rather than a wide floody wash. That makes it a strong choice for lighting up distant targets when you're clearing a large area or working past close range.
