Received in two days thanks to Prime Membership. The weapon light is very nice I have a pretty solid background involving weapons and accessories and also other stream light products. The weapon light feels very lightweight and very durable. It has a nice black smooth finish from the factory. The 625 lumens is very blinding as well it is a very crisp white light with a solid center beam for a lot of throw if you need it to see targets clearly out to I would say 60-70 yards I would say as an estimate without measuring... Also has a nice peripheral glow to illuminate areas around your focus. I have not extensively used this light yet but I don't foresee an issue. It can be programmed for a few modes like strobe and low/high intensity. It also comes with two tail caps a click on/off or just hold for momentary and a flat pressure switch with the same functions. The mount is also very nice and is part of the gram of the light it has a knurled knob kind of like a traditional AR 15 removable carry handle. It Feels very solid and have no worries when it comes to live fire. Anyway I would buy it if your in the market for a quality inexpensive weapon light you can always return it or send it to stream light it's pretty much worry free. Enjoy and remember target discretion. ... show more

    • You pay for brightness, great value, light weight, high quality.
Size: 5.0 x 1.2 x 1.5
High quality and great value as a complete rifle light kit. It has everything in the package to rail mount or M-Lok which is what I did, even has zip ties for cord management. Nice white high Kelvin light, You pay for lumens and if you read reviews that it’s “not bright” or “could be brighter” you must understand that the higher the lumen count the brighter and more distance the light will reach. Decide the range you’re looking to light up and match the lumen intensity and you won’t be disappointed. If you’re trying to light up a room, hallway, or a small backyard this works well, hunting hogs from a helicopter this wouldn’t be bright enough. For my intended use this was the lumen level matched to my purpose and the value, weight, size, and quality, are outstanding! Really a great all in one kit from an industry leader. ... show more

    • Weight saving model
Size: 5.0 x 1.2 x 1.5
Probably the best out of Sreamlight’s rifle light lineup. Very lightweight, low profile, bright for its size. Range & throw are about what you’d expect from a light this size & price: very good. This goes well on any build that you’re trying to balance/save weight on, noticeably lighter than the 1000 lumen models. ... show more

    • High quality light!
Size: 5.0 x 1.2 x 1.5
I have two of these lights. Absolutely excellent! I really like the functionality of the touch pad and the ten-tap program. Only thing to beware of is that the rubber touch pad picatinny mounts are REALLY hard to put on. Certainly no worries of them coming off after installation, but wow is it hard to get on. Also, the M-LOK adapter (p/n 88300) has some fitment issues with the Aero Precision GEN 2 Enhanced M-LOK handguards due to the angle of the adapter. It will work, but is kinda janky and by no means perfect. ... show more

    • Solid, full featured Scout wannabe that is excellent value!
Size: 5.0 x 1.2 x 1.5
Solid light that comes with a bunch of accessories to help you mount the light and pressure switch. Here's a summary of my experience with it. Took the Picatinny mount off and put it in my gun parts drawer. I decided to use an Arisaka keymod inline mount. Since the ProTac 2L is a bit longer than a scout, requires a ball T15 torx driver to install. Light is very easy to operate. If you don't dig your thumb into the light, the switch is recessed enough to allow momentary-only function without ever accidentally turning the light on all the way. It takes a deliberate press with the tip of your thumb, digging into the light, to turn it constant on. The pressure switch that comes with the light is nowhere near as good as a SureFire Scout switch, but keep in mind that the SureFire switch costs $75 and this light came with a $100-ish light. It works well, I haven't broken it, but I like the simplicity of the tail cap that I decided that the tape switch was unnecessary. I may put the tape switch back on and play with it more and find better ways to tuck away the cables. If I do so, I recommend putting the tailcap in the grip storage compartment of your rifle (if you have one) in case you need it again. ... show more

    • Best Value For Your Money
Size: 5.0 x 1.2 x 1.5
I’ve had this light for over a year now and I’ve beaten it up like crazy and it’s still running strong. I was originally planning on upgrading to a surfire but I haven’t found a reason to upgrade. I’ve dropped it on concrete and left it in the snow and I’ve only had one issue with the pressure pad coming unscrewed under recoil but that was an easy fix. I was surprised how far this light sines for 625 lumens and was able to use it to shoot out to 100+ yards at night. Compared to my friends m600 it shines just as bright and I had less issues than he did so I’m planning on sticking with it for the time being. Definitely a light I would trust my life to and the best bang for buck rifle light you can get! ... show more

    • Better than Surefire for the Price!
Size: 5.0 x 1.2 x 1.5
Absolutely fantastic! I'm a retired state trooper and in the Army Reserve. This light is beyond belief at over 620 lumens! I refuse to pay for a Surefire light when this one is 1/4 to 1/3 the cost for a top shelf product. I compared it to my Army issued Surefire and the Streamlight was of comparable quality and WAY brighter, not to mention smaller. A buddy of mine on a local SWAT team was very impressed with this light. It is very well constructed and comes with an extended wire finger on/off switch or you can use the push button switch on the back of the light. With the push button you can turn the light on (and leave it on) or press it just enough to temporarily turn it on/off. With the wire you can only turn it on temporarily, like most other lights. I won't buy another Surefire as long as these are available, they take up less room on the rail, cost less and are MUCH brighter. Note: The rail attachment hardware is permanently installed to the light - you can't remove the rail attachment. I highly recommend you try one of these first if you are contemplating a Surefire light. ... show more
