Streamlight TLR 7 Sub HL X Impression

 The TLR-7 Sub HL-X is a 500-lumen pocket rocket designed specifically for subcompact pistols—think Glock 43X, Sig P365, or Springfield Hellcat. It’s powered by a CR123A battery (included, because nobody wants to dig through their junk drawer for one), weighs about as much as a Snickers bar, and clocks in at just over 2.5 inches long.

Now it's pretty much as powerful as a full size streamlight TLR 1 HL.

TLR 7 Sub HL X Dimensions

• Weight: 2.49 oz
• Length: 2.51 inches
• Lumen: 1000 lumens
• Candela: 10000 candela
• Battery: 1 CR123A or 1 SLB9 battery(Rechargeable)

The Streamlight TLR 7 Sub HL X is literally the same as the original Streamlight TLR 7 Sub. While the TLR 7 HL X has a longer light head to produce 1000 lumens and 10K Candela, the TLR 7 Sub HL X stays the same size.

it’s slim enough to pretend it’s not even there. IPX7 waterproofing means it’ll survive a downpour or an accidental plunge into your dog’s water bowl.

TLR 7 Sub HL X Construction

This thing is the Clark Kent of weapon lights—unassuming but effective. Its made with 6061 T6 aluminum and most users love how it hugs their subcompacts like it was born there, avoiding the dreaded “flashlight bigger than the gun” look. 

The switches are intuitive and it comes with both high and low switches.

I personally like to upgrade it anyway with the Emissary Development paddle shifters because they extend it back more for the index finger making it way more ergonomical for momentary light activation while keeping a good grip.

Lumen and Candela Intensity

If you're interested in the TLR 7 Sub HL X, then this is the only thing we really be paying attention to. Streamlight has done a great job by increasing the light output while keeping the light exactly the same as the original.

The 1000 lumen appears much brighter than just the 500 lumens, and the 10k candela can now see targets at about 50 yards. While the TLR 7 Sub can barely see anything in the dark past 25 yards unless you really look for it.

Now the only thing to note is that only the SLB9 battery can give the light the maximum output, which the light comes with a SLB9 battery without having to buy them separately.

The CR123A battery? Reliable, sure, but in the age of USB-C everything, it feels a little 2010.

In a way this is as bright as a full size light and you can say bye bye to your original TLR 7 Sub.

Beam Pattern

The beam pattern is exactly the same as the TLR 7. It's got a balance throw and spill, and of course I can't compare this light with the Surefire X300 Turbo, but for up to 50 yards, the TLR 7 Sub HL X does a great job lighting up the scene.

It's great for conceal carry and range use at night.

For those who complained about the 500-lumen output in the past—some swear it’s perfect for defense, while others insist, they need a mini sun strapped to their gun. “Great for my apartment, useless for my backyard,” Well the TLR 7 Sub HL X is here to stay.

Compatibility

The Streamlight TLR 7 Sub HL X is made for subcompact frame guns like the Glock 43, Glock 48, Springfield Hellcat and the Sig P365. The lights are marketed in 4 different models with different mounts, but they are basically the same.

I wish Streamlight could just include these mounting adapter inside the package, so the user doesn't have to buy 3 different models separately if they own all 3 guns, Glock 43, Sig P365 and the Hellcat.

Now if you're using a custom P365 frame with a pic rail, then you can just stick with the Glock model because that's basically 1913 rail.

Based on my testing, I have all 3 of the original TLR 7 Sub models, and I just use the mount from the those on the HLX model.

Use Cases

Home defenders needing something reliable for midnight “what was that noise?” scenarios. Conceal carry users carrying subcompact guns will love this light.

Even cops dig it as a backup piece. It’s also a solid training tool—new shooters appreciate the simplicity, and instructors love that it doesn’t add distracting bulk. Just don’t expect it to moonlight as a searchlight or competition gadget.

Final Verdict

The TLR-7 Sub HL-X is not flashy, but it works. It now closely matches the performance of a full size light.

Since the TLR 7 Sub design maintained its original body while the lumen output is increased, this light’s a slam dunk for subcompact gun users without having to buy new holsters.

Just pair it with the right gun, manage your lumen expectations, and keep a spare battery in your range bag. And for the love of all things tactical, read the mount compatibility chart before you buy.
