   I haven’t tested it at my indoor range but indoors it is very bright and the strobe will definitely throw off a intruder. Mounted nicely using the mlok mount it came with. Make sure to mount it just behind the muzzle at 3 or 9 o’clock.

   I just ordered this light a month ago and finally got around to installing it. Unfortunately I am outside the return window by a week or I would be sending this back. Immediately I noticed the rubber cover for the button housing was loose and not properly seated. Taking a closer look at it you can see the rubber is torn, most likely this is why its not seated properly, Images will not reflect the tear as it would require trying to seperate the rubber lip to demonstrate it. I decided alright no big deal I’ll just use the light anyway, I go to install the pressure switch. Doesn’t work because the bottom metal clip is broken off. Save your money, stay far away from this light. *Update* After a lengthy battle with streamlightoutlet.com support, after 5 representatives. streamlightoutlet.com was unable to provide a working solution to resolving the issues I ran into. However I took it upon myself to reach out to the manufacturer via their website and they have offered to send me the replacement parts. This was completely of their own volition and unexpected. I am thrilled Streamlight has made right by this. However with that said to the 5 representees I spoke with from streamlightoutlet.com, your responses we completely unacceptable and lack luster. None of the 5 people, emails included were able to even edit the template responses. They copy pasted every response back to me and could not be bothered to edit the template with my relevant info. Furthermore, streamlightoutlet.com wanted to charge me to handle the issues, Streamlight took it upon themselves to just send me the replacements. streamlightoutlet.com additionally wanted me to return over $400 dollars in additionally purchased items just to remedy what could have been a simple fix. I would highly encourage anyone reading this to purchase direct from Streamlight as they actually care about their customers, where as streamlightoutlet.com could not be bother to even remedy the situation appropriately.

   Didn’t like the tail cap it came with, changed it with a non removable cord one, great light solid mount

   I’m sold on their Protac HLX line for long gun weapon lights. I bought this specific model because I’m already invested in these USBC rechargeable batteries.

   I was also particularly interested in the push button AND tape switch capability.

   Couldn’t be more disappointed with this flashlight. Honestly delivery was on time no issues with streamlightoutlet.com. Product arrived in the original packaging but it looked like someone had taken a bite out of the top left corner. Was anxious to see it work but it arrived with a completely dead battery and needed to be charged first. Charged the battery all night got up in the morning popped the battery in and it doesn’t light up. After messing around with the end cap I noticed it would light up if you would loosen the cap to the point it’s almost falling off. I bought an Olight and returned it due to a torture test comparison video on YouTube. The Olight was completely out performed by Streamlight unfortunately never had a chance to experiment with the light. It’s going back!! Update less than a week after receiving the first dead Streamlight my replacement came in. I charged the battery all night and first thing in the morning put the battery in and received the same result. Flashlight will not turn on completely dead. Contacted Streamlight and they will try to make this right. Very Disappointed!! While it’s the perfect size light I have little faith in the company and their products now. And to think they were so highly recommended to begin with I would have never thought this would be an issue. FYI if you just return it to streamlightoutlet.com it’s faster and free. Going directly to Streamlight has cost me an additional $13.80 for shipping. Somehow I don’t believe this expense should be passed onto the consumer as it’s not my fault the product was dead on arrival. Now I would understand if you’re returning for a repair after years of use but this charge was icing on the cake at this point. Double thumbs down to this point.

   This is the cheapest I’d go on a weapon mounted light. It checks all the boxes. The light is bright. The construction is sturdy the switch and buttons on both the light and the tape switch work. Great streamline has a killer warranty if you ever need anything regardless the battery life is great. I haven’t had to charge it since I bought it and I’ve used it quite a few times

    The screws for the M-lock attachment don’t fit. This is the only stream light product I’ve ever had a problem with. I can still attach via picatinny but the mount is garbage. I’m extremely disappointed.

    This is a great light – extremely bright (lights up my entire yard at night like daylight), installed easily, and gives you the option to use regular CR123 disposable lithium batteries while the supplied battery recharges.
