Description
For a long time, if you carried a subcompact Glock you were stuck choosing between a tiny light with a weak beam or nothing at all. The TLR-8 HL-X Sub changes that math. It packs a genuine 1000 lumens and 10,000 candela into a body sized for the short rail on a 43X or 48, throwing a beam out to around 200 meters. That is a real high-output light on a gun most people carry every day, paired with an integrated red laser for fast, point-and-shoot target acquisition.
What the TLR-8 HL-X Sub Brings to a Subcompact
The multi-fuel setup is the standout here. It ships with Streamlight's SL-B9 protected lithium-ion battery pack that charges right through a USB-C cord, and it'll also run off a single CR123A lithium cell if you'd rather keep spares in a drawer. On the rechargeable pack you get the full 1000 lumens for about 30 minutes, or you can program it down to 500 lumens and stretch that to an hour. Drop in a CR123A and you're looking at 500 lumens for roughly an hour and a half. The red laser sips power and runs for hours on its own.
Controls and Build on the TLR-8 HL-X Sub
The rail-grip clamp lets you mount and pull the light without ever putting a hand in front of the muzzle, which is exactly how it should work. You get ambidextrous rear paddle switches with high and low positions, plus a set of interchangeable paddles in the box so you can tune the feel to your grip. There's a safe-off feature that keeps the light from firing up by accident and draining your battery, and the aircraft-grade aluminum housing carries an IPX4 water-resistance rating for wet-weather use.
One thing worth knowing: this is the red-laser version. Green shows up better in daylight but costs more, so if you're mostly running this for low-light work or want to save a bit, red does the job well. Just make sure you're grabbing the correct model for your gun, since the mounts are cut specifically for the Glock 43X and 48 rail.

Frequently Asked Questions
Will the TLR-8 HL-X Sub fit my Glock 43X or 48?
Yes, this model is cut specifically for the Glock 43X MOS, 48 MOS, 43X RAIL, and 48 RAIL. The mount is matched to that short rail, so it clamps on securely without hanging past the muzzle. If you carry a different pistol like a SIG P365 or a Hellcat, you'll want the version made for that gun instead.
How does the TLR-8 HL-X Sub get power, and is it rechargeable?
It's multi-fuel, which is one of the best parts. It comes with Streamlight's SL-B9 lithium-ion pack that recharges over a USB-C cord, and it can also run off a single CR123A lithium battery if you prefer swappable cells. That flexibility means you can top it off at home or throw a spare CR123A in your bag for backup.
Should I get the red laser or spend more for green?
Green lasers show up noticeably better in bright daylight because green light is more visible to the eye, but they cost more. The red laser on this model works well for low-light and defensive use and saves you some money. If most of your use is indoors or after dark, red is plenty.
How bright is it and how far does the beam reach?
On the included SL-B9 pack it puts out a full 1,000 lumens and 10,000 candela, throwing light out to about 200 meters. That's a serious step up over older subcompact lights that struggled to light up a room. You can also program it down to 500 lumens to stretch the runtime when you don't need the full output.
