Bright idea
If you are looking for a reliable gun light, this is for you. Streamlight is a well known brand, and this product is representative of the quality they are known for. Easy to install on M-lock rail, with included hardware to do so. The battery has to be removed to charge, only a minor hassle. This is at a good price for value.

Would buy again
Amazing light. It mounts very easily to my rail and the attachment to turn it on/off/strobe also amounts very easily to the top of my rail so I can control it with my thumb. Strong light, great battery life. Not sure how size compared to others, but I am OK with the size of this as it isn’t too big in my opinion. buttons are also extremely smooth and low profile.

88066 Pro Tac Rail Mount 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.

Very sturdy and bright
I originally had an O-Light that I ended up giving to my father. I wasn't super pleased with the build but when I got the Streamlight (for maybe $50 more then I paid for the O-Light?) there was no going back! Such a great, sturdy build and is SUPER bright! Also has some great weight to it! Not too much, not too little!

Very Good 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.

Awesome product, but the battery was DOA.
I ordered this after hearing good things and having very good experiences with Streamlight in the past. The light has a good, solid mounting option. The light it self is bright, programmable and useful to about 150-250 yards depending on the conditions. For indoor conditions the throw is wide and bright enough to illuminate most of the room but the hotspot on the high “setting” is right on the edge of being too bright. The only real complaints are the tail switch reduces the waterproofing rating and the battery was dead on arrival. Pressure pad mounting system is annoying to put on but does the job well. I tried to use Amazon’s “replacement of broken or missing parts” option and spoke with no one who could understand plain English and they kept trying to return the item for me; despite specifically stating I just wanted them to send a replacement battery ( Amazon has the replacement battery for sale). I ended up having to contacting Streamlight directly because Amazon’s customer service was useless. Needless to say Streamlight’s customer service was down to earth and wanted to help immediately, they shipped the replacement with no hassle, no questions asked. Awesome customer service on Streamlights part.

Extremely Bright
Great light. Incredibly bright. Mounts easily. I used a Schaffer Machine pressure switch mount for the pad. Excellent setup.

Streamlight Delivers Again - You can't beat 1000 lumens!
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.
