They need to know that their flashlight will deliver the light they need for the task at hand. Whether it’s lighting up a whole room, throwing a beam way down a path or up to the sky, or reading a map without being seen. When size and run time are also part of the performance, people know they can trust Streamlight to shine brighter, work better, and last longer.

    • Great WL for the money.
Color: Black Style: Protac Rail Mount HL-X, 1,000 Lumens Pattern Name: Light
Great value for the cost, I've run Sure fire lights in Iraq and TLR units when I taught civilian side. And this has held up just as well. Love the dual high/low mode. As anyone who's ever done close in room clearing will tell you, sometimes you CAN have to much light and it sucks catching yourself half blinded with bounce back. So being able to drop down with just a quick tap is great. Then when you get outside tap again for the extra throw to check woodlines or open fields. Do recommend a steel zip tie to lock it to weapon forearm just incase. It's easy to hit a doorframe going to fast and it keeps everything on the rifle in an emergency. Great buy, stop reading and order it. ... show more

    • 88066 Pro Tac Rail Mount Light
Color: Black Style: Protac Rail Mount HL-X, 1,000 Lumens Pattern Name: Light
I trust Streamlight as I have a TLR-7 and the build quality, fit and finish really impressed me for the price, and the brightness was very good (it’s bright enough that looking directly into it will nearly blind you temporarily). It also was great in how it attached, ease of use etc. I liked everything about it, so I went with Streamlight for this purchase as well. I have no complaints so far, it seems like a solid light and basically exactly what I expected (I haven’t used the switch, as I feel I can thumb the button just as easily with it on the left side, and won’t accidentally hit it). The brightness is just as strong as I expected as well. In regard to a review talking about getting a fake one, I did not (mid 2022). The build quality is just as I’d expect, it’s robust and the finish is very nice. It’s very easy to attach to a pic rail (if you have an MLOK guard you just need a little pic rail, they’re cheap), and it has a hand-tightening nut attaching it. The nut has a slot cut into it as well so you can use a tool (a knife, whatever fits) if you ever needed to loosen it if it seizes up a bit. The only thing that surprised me a bit was the size. It’s a little bigger than I expected and hoped for, but that’s why you should research before buying anything lol. It’s fine honestly, just a little larger than I realized. I would’ve preferred a slightly smaller/lighter light, but the fact that it’s big enough to be used by hand is probably a benefit anyway. I suppose it’s a normal size for a light of this nature, I have never owned one so it’s new for me. It looks a little big on the there in terms of aesthetics, that’s all. If anything goes wrong with it I’ll update. But as of now I recommend it and I definitely recommend Streamlight. I like their products. ... show more

    • Very Good Light
Color: Black Style: Protac Rail Mount HL-X, 1,000 Lumens Pattern Name: Light
This is a very good light and that isn't considering the low price. It's just good in general. The price makes it even better. The light itself appears to be built well. Light is a bit of a cooler tone but almost neutral. Hotspot in the center of the light is BRIGHT. Can illuminate things well at quite a distance. Beam itself isn't perfect but will not matter or even be noticed by virtually anybody buying it. The pressure switch works. It mounts fine. Everything works. Now I love paying for quality but I just cannot fathom how someone will spend $400+ on an arguably worse flashlight and a better pressure switch from a competitor. This is as good or better in ways for almost 1/3 the price. People say "oh the military uses that brand!" Great. Most police and fire departments use Streamlight and like them. Some say "oh the other brand is made in America!" Yeah they're an american company. They manufacture some things in the U.S. but look on the box or the light itself. You will not see "Made in U.S.A." on it, because there are parts of the light not made in America. Streamlight is also an American company. So you can spend 1/3 the money on this better flashlight trusted by our first responders or you can buy a 3x as expensive light that actually illuminates things worse and isn't even technically made in America. Either way you're supporting an American company. I'd highly recommend buying Streamlight. ... show more

All hype and marketing from the other light manufacturers aside, this Streamlight HLX is the best long gun light there is at this price range and feature set. Period. Why. Pay. More? Light: The options and 10 tap programmable features are a win. I prefer the low/high setting. This light is bright AF on high. The low setting is great for indoors and training. Tape Switch: Personally I really like the momentary tape and constant on button option. That's definitely a win. Picatinny light mount: The mount is just OK. Slot it where you need it, twist it down tight, forget about it. For a better mount option, go with the Arisaka brand picatinny Gear Sector Offset Scout Mount. They also make M-Lok and KeyMod mounts as well, all for <$50 Switch mount: Streamlight knows their tape switch is BS. The two rubber picatinny switch mounts and zip tie system are ok for light duty and range use, but for serious life and liberty use, don't bet your life on them. The only solid option is to go Cloud Defensive, $80. Buy once, cry one - get both as a combo deal from Cloud Defensive and be done with it. Conclusion: The kit is a solid 4 stars. Streamlight kept the price down by not adding in a more solid tape switch mount. Sometimes aftermarket accessories is the way to go. I highly recommend Streamlight for all of your weapon and pocket light needs. ... show more

    • Streamlight Delivers Again - You can't beat 1000 lumens!
Color: Black Style: Protac Rail Mount HL-X, 1,000 Lumens Pattern Name: Light
This is an awesome, sturdy weapon light. I’ve always trusted Streamlight, and this one definitely lives up to their reputation. I love that it comes with everything you need, including the tail cap and pressure switch, giving you flexibility depending on your setup or preference. Whether you’re mounting it on an AR for home defense, duty use, or training, this light performs flawlessly. It's a fantastic value, especially when you consider the solid performance and all the included accessories. ... show more
