  • Output: 12,000 candela peak beam intensity; 630 lumens.
  • Runtime: 1.25 hours

First Impression

First, with aircraft aluminum body, black color, it looks so luxury and elegant. It’s not like in the old version – the TLR-1 (100 and then 300 lumens), the TLR-1 HL (630 lumens) is equipped with C4 LED delivers 12,000-candela peak beam intensity. It is a rail mounted tactical led flashlight with features: full on, momentary on and strobe effect, which are easy to control with either hand.

In addition, the Streamlight TLR-1 HL was built-in with some options “key”, which are interchangeable to many pistols. It included Glock, Beretta, Smith & Wesson 99 TSW and it’s as easy as removing the nut on the side and slipping the new bracket key in.

Operating & Features

The Streamlight TLR-1 HL does not have programmable or multiple brightness mode settings, it is only one level bright for full-on, momentary on and strobe effect that is why the runtime just about over one hour.

However, the TLR-1 HL beam is very good. It is a nice flood beam as well as a large hot spot. It’s a mix of throw & floody and the light will handle the stress of firing with no problem.

I want to say that a person with medium size hands shouldn’t have a problem to master the toggle switch but with your hands is small, the TLR – 1 HL also has a rigid pressure switch attachment available in case the toggle switch isn’t suitable to your shooting style.

The Price

The TLR-1 HL tactical led flashlight costs around $140. It is not a small investment. However, I think the price is very reasonable at all. It’s the nearest competitor in this power and quality range runs well over $200, which making this Streamlight TLR-1 HL tactical led flashlight offering a great of a deal.


I tested the TLR-1 HL in the dark room. After turning off all the lights of the room, and then turned on TLR-1 HL with full-on mode. I feel that my room is brighter than when all the lights in the room are turned on. I aimed the TLR-1 HL at the ceiling, it reflects enough light to see clearly and easily anything in the room. In my opinion, the Streamlight TLR-1 HL is a bit high bright for indoor using but for outdoor it would be greatest.

I tested it with Glock – GL19. I install the GL key (standard key or universal rail) and it keeping the rail slot very well, which will eliminate any moving forwards and/or backward which might lead to loosening.

Generally, the Streamlight TLR-1 HL is fit & feel are great on the Glock 19. It’s is tight on the G19. I just need to tighten down the screw by a hand, and then just use a small knife or coin to tighten more about 1/4 turn. You will not need more effort for tightening down.

Moreover, the control modes are also in the perfect spot for me, I feel very comfortable and convenient when pressing on the light switch. In addition, the strobe mode is also very easy to activate without loosening up or changing my grip.

Streamlight TLR-1 HL vs. Surefire x300 ultra

For now, I will be offering a side-by-side comparison of the Streamlight TLR-1 HL and the Surefire x300 ultra. I have some experience with each. There are obviously many other models available, including some with lasers, but I’m focusing in the Streamlight TLR-1 HL & the Surefire x300 ultra since they seem to be the most common. Both of the weapon-mounted led flashlights is attached and tested with Glock 19.

Control Switch:

With each model, they have a similar about looking and function of the control switch, but there are a bit of differences.

For the TLR-1 HL, the right-handed of shooter need to push the switch up for momentary on or push the switch down for constant on. If the shooter was left-handed, just doing the opposite, the switch is one piece that extends to two sides of the light across the face of the trigger guard. See pictures below.

For the Surefire x300 ultra, the shooter will need to push slightly the switch to forward (pushing the switch toward the muzzle of the gun) for momentary on. The full-on mode turned on by pushing the switch either up or down.

Pressure Switch:

The Streamlight TLR-1 HL and the Surefire x300 ultra are also has a pressure switch available too. Whether it’s sometimes called with a different names such as a remote switch, contour switch, or pressure switch. You should choose and buy the pressure switch model that is suitable for your particular pistol so that it properly fits around the bottom of the trigger guard and on the front strap so that you can activate the remote switch with a squeeze of the middle finger.

Streamlight TLR 1&2 Contoured Remote Fits Standard Glock

The Streamlight TLR 1&2 contoured remote switch (fits standard Glock) fits around the bottom of the trigger guard and curves around to the side of each side of the trigger guard. The exterior of the Streamlight TLR 1&2 contoured remote switch is a slick metal-feeling shell that seems like it will stand up well to use.

Grip Switch Assembly for SureFire X-Series WeaponLights

The Surefire X300 DG grip remote switch (fits standard Glock) attaches in the same way but it is a little more streamlined as it does not wrap up on the sides of the trigger guard. The push button pad seems a bit smaller on the Surefire x300 ultra. The exterior protective coating of the Surefire X300 DG grip remote switch is a thin layer of a rubbery material that can possibly tear over time.

I prefer the slimmer profile of the Surefire X300 DG grip remote switch, but I’m worried the thin rubber layer coating will be scrapped. The Streamlight TLR 1&2 contoured remote switch is a little bigger, but its exterior is more durable.


The Streamlight TLR-1 HL has a large screw on the left side of the gun that has spring tension on the rail attachment on the right side of it. Once the light is on the rail, and the horizontal “key” is in the notch on the rail, this screw is tightened easily by using a screwdriver or coin, etc and the light is safe to the rail.

The Surefire X300 ultra has a lever on either side of the light that is depressed against spring pressure to allow the light to slide onto the rail and locks in place once the horizontal “key” clicks into the notch on the rail.

Both are very safe when installed without a wiggle. Overall I find the TLR-1HL a bit easier to install or remove. In reality, you won’t be taking it off and putting it back again many times so that it is not a problem.

Each weapon-mounted led flashlight comes with a universal key for attaching to common rails (Glock rails) as well as other keys that can be put on such as 1913 rail, etc. The TLR-1 HL system of swapping these out is easier that requires removal of a single hex-head screw, where the Surefire X300 ultra requires removal of the hex-head screw.

Which One Should You Buy?

There are main features of each that I prefer over the other, so it is hard to say. I have to be honest when this one is around half the cost of others. It’s hard to get a decision. I like the push-forward for momentary on the mode of the Surefire X300 ultra but it is difficult to engage or disengage when installing and removing.

The momentary on for each is pretty easy to activate, just different from each other. I recommend the pressure switch for either. You are just easy to activate with a simple squeeze of your middle finger and not have to use your trigger finger to activate the light.

The assumption is that the Streamlight TRL-1 HL is running a similar LED as the Surefire X300 Ultra. The lumens difference is most likely two things.

  • The Surefire X300 ultra tends to be really conservative on its ratings and
  • The TRL-1 HL could be going with a lower run time to get a little more light.

It is hard to say which one is better, both weapon-mounted lights will get the job well done. I think you’d be happier with the Surefire X300 ultra, but you’ll save a couple of budget with the Streamlight TRL-1 HL.


The Streamlight TLR-1 HL weapon-mounted led flashlight is great. I’ve always been impressed with Streamlight’s quality and especially for a fair price. I like the TLR-1 HL than TLR- 2 or TLR- 3 because it is much brighter than the TLR-3, and has an aluminum body (vs. plastic, composite) for not too expensive. The TLR-2 is much more expensive because it is equipped with laser sights.

Personally, I’d go with a Surefire X300 ultra. The TIR lens is a much nice optic, I like the tool-less install and removal, I like the momentary on, the Surefire will have the USA build high quality vs. Chinese.
