      Perfect EDC February 3, 2022

      If you are new to the enthusiast flashlight world or just looking for an EDC that is better than a pen light or cell phone light, this is it.

      The standard size is the 18650 battery which is fine if you need 30 minutes to an hour of runtime. If you are like me though, I just need about 15-20 minutes of runtime to troubleshoot a problem in a dark room or cabinet and then go grab the tools I need or make a quick repair with my pocket tools.

      If you are like me in your intended use, get the 18350 tube, the SST-20 4000K 95CRI emitter and the magnetic tail cap. I jave a SST-20 5000K and it's brighter, but it washes out colors on wiring. After you play with turbo a few times on the 5000k, the 4000K is the one you want to live with. I don't even use the 5000K really except with the 18650 outdoors to do something like take out trash or light up the yard.

      The 18350 will also be the size you want to live with and the magnetic tailcap adds minimal weight and attaches to under the hood of your car, an equipment cabinet door, a knife blade stuck into wood etc.

      I've carried many lights including pen lights and other brands and this is the winner right here for EDC. This light introduced me to these brands and I subsequenly ordered more with different emitters and bodies, but always come back to this one. Better than the KR4 or anything else.

      I've carried it a couple years and use it daily and the titanium looks great and the patina on the copper looks great and have no problems.

      amazing. March 19, 2021

      This flashlight is nothing short of amazing. Its the perfect size. The interface is fun and many options to play with and to top it all of its titanium. 5 stars.

      My new favourite Llight March 12, 2021

      A wonderful light, My new favourite by far. Very configurable, super output.

      Great light! January 17, 2021

      Build really strong, it's titanium and its thick! You can't go wrong by buying this flashlight.

      VERY BRIGHT January 13, 2021

      REALLY Bright, REALLY epic User Interface January 2, 2021

      This Light is bright, ridiculously bright. The max mode is really only meant for a short time. I got the 2700l SST-20 mule. Putting it on candle mode is super convincing and it looks exactly like an incandescent light in color. The dimmest mode is perfect for indoor use in the middle of the night. The switch backlight is really handy for finding the light on my desk and when I set the switch light to low it is dim enough to not bother me at all in the middle of the night.

      This thing is THICK, really heavy duty machining, really nice sturdy threads as well.

      Get it November 24, 2020

      This is an awesome light. It's flashy and functional. If you want to spend sub 100 on a light with many features this is the one to get.

      Outstanding Light November 16, 2020

      This is by far the best light I have ever owned. I use this light for work (industrial maintenance tech) and it is perfect. It has already taken its drops and dirt with ease. Most (Fenix, Olight, Nitecore) goneith the standard 6500k tight hot spot type of light whereas the D4V2 gives a uniform beam perfect for electrical cabinets and dark corners. The UI is also far superior to the big brands. While at first glance it looks complicated in use it is very simple. The high CRI is also of high importance to me because it really helps distinguish wire colors where the typical 6500k CREE.... won't cut it. To sum it up the D4V2 is not just for flashlight hobbyists (though i consider myself one), it is a great fit for everyday work use as well. I am happy I clicked the banner ad on BLF.

      Damn work of art! July 26, 2020

      Wow! Such a cool piece. I love the weight of this light, feels sturdy. I can’t imagine any other light out there that tops Emisar. Thanks for making absolute perfection in a pocket light.

      Everything you need in a light, and more! July 11, 2020

      This is really the epitome of flashlights. It's bright for when you need it to be, and is functional with a couple party trick modes. The titanium is a little heavy, but worth it for the increased durability over aluminum. Note that it is silver, not black like the first picture. Will not fit protected cell 18650's, and you have to tighten the cap on fairly tight in order to make a solid connection. Super thrilled with the light, and looking forward to buying more from intl-outdoor! Thanks Hank.

      GREAT LIGHT June 24, 2020

      Love this light January 20, 2020

      Ok, I have it bad I must admit, at this point, I have over 100 flashlights in a collection that's about a span of two years of collecting and this is my favorite. I get dressed and every day have issues with what light to carry and I'm known to carry more than ill admit but I always carry my D4V2 TI because with the UI it's like having a dozen different lights in one and I actually use the features it has from the timed candlelight that's like a fireplace in my room at night to the multi-color programmable secondary lighting this light is awesome I could write a book on why and ever since this light I look for lights with similar features but that's tuff nothing really out there matches up its the best EDC period

    • Bernhard
      Emisar D4V2 and D4S are my preferred flashlights. Thank you for your Fine work. January 16, 2020

      Best flashlights. I like them the most.

    • jasaero
      Awesome, but a minor niggle on threads January 8, 2020

      Awesome light, but seems Ti is not square cut thread I guess to save cost with higher material cost and harder to cut Ti... So has sharp threads that bind easier with bit of debris.

      Ich bin sehr zufrieden mit der Lampe, sehr gut verarbeitet macht richtig Spaß. November 16, 2019

      Alles gut geläufen keine Fehler Spizen Produkt

    • Brando555
      The fit and finish with the titanium and copper is just ridiculous. It looks great and it's flawless. I like the backlit switch, and auxiliary lights, it's sort of gimmicky but overall it it is anything but gimmicky. Just a high quality flashlight with qu November 16, 2019

      Awesome EDC light and Wow factor!

      Лучший ЕДС фонарик November 10, 2019

      Давно приглядывался на медь/титан, а тут всё и сразу: медь, титан, цветная подсветка, правильное управление, лучшие диоды на выбор, магнит, клипса, цена ниже конкурентов - астролюкс, светлячки. Я остался очень доволен. Но можно сделать ещё лучше: 1. клипса не плотно прилегает к трубке; 2. резьбы с задирами; 3. плавное загорание/затухание основных диодов; 4. плавное изменение цветов подсветки; 5. цвет подсветки в кнопке в зависимости от заряда батареи; 6. уменьшить толщину стенок трубки и вес фонарика; 7. встроенную зарядку батареи.
