Good mounting system for the light, the light itself is bright and has decent dispersion. The big plus is it’s about half the price of Surefire.

I love this little light. This is the 3rd one I’ve purchased. It’s easy to mount, the tape switch works great and it’s super bright. Double press the switch and it strobes too.

For the price of this light it’s great. The light is programmable by tapping the pressure pad and you have 3 programmable options. The mounting hardware is durable. The pressure pad is plastic but works great for most applications. I don’t recommend buying used like I have because not all of the hardware to mount the light was there. But overall a good option for budget minded folks or getting into WML

I’ve got a bunch of other lights in the same “lumen” category, however this is the brightest 2xCR123a light that I own. The ability to switch between tailcap and pressure pad is also great. It’s a shame it only support 1913 rail. I drilled out the holes on the end and put some M- LOK T-Tnuts through to direct mount on an M-LOK rail (pressure pad only – light still 1913).
Still on my first set of batteries so can’t talk about battery life and haven’t had it long enough to weigh in on durability. For the price seems like a very high value light.

The Streamlight 88066 ProTac Rail Mount HL-X is an exceptional weapon light that delivers impressive performance! With a powerful 1000 lumens output, it provides bright illumination, making it perfect for tactical applications or home defense. I love the multi-fuel feature, allowing it to run on either CR123A batteries or a rechargeable battery, which adds to its versatility. The included remote switch and tail switch make it easy to operate, even in high-pressure situations. The sturdy construction ensures durability, and the sleek black design fits seamlessly on my firearm. If you’re in need of a reliable and powerful weapon light, I highly recommend the ProTac Rail Mount HL-X!

Really like the light. The mounting system for the pressure pad on a picitany rail isn’t the greatest, the plastic parts it comes with hold it on but it’s not sturdy. I might replace them or do a different mounting system. Overall the light is very bright and mounts to the gun very nicely. Very happy with the purchase for the reasonable price point

Comes with everything you need to mount including zip ties. Perfect form and function.

I’ve used it on my .223 and my shotgun. It just plain works, and holds up to even using slugs. Solid choice.

It’s very well-built, bright as hell, easy to mount, and just works quite well on my rifle. I’m freaking thrilled with it! The battery life is really impressive too, considering the scope and brightness of the light. The strobe function is awesome and easy to actuate too. I did a ton of research about rifle-mounted lights and these always came highly recommended. I now understand why.
