Emisar D4V2 Flashlight Review

This upgrade from the original D4 is one of the most widely recognized flashlights in the business by enthusiasts. It comes with auxiliary LEDs, a new knurling, and a number of great optional upgrades including a boost driver, floody optic, and extra SS bezel. 

The affordable but unique Emisar D4V2 is a great option for enthusiasts even though it boasts quite a few features that many of us might wonder “why” they even included them in the first place. 

Either way, let’s dive into the Emisar D4V2 review.

Battery and Power 

The D4V2 requires an unprotected 18650 battery with a flat top. The reason for this is because the flashlight is designed to be a hotrod so protected batteries would prevent you from accomplishing that. The higher amperage cell you can provide for this flashlight, the better off you’ll be. 

Keep in mind that this flashlight gets HOT. It’s designed to push more power to the light which reduces the overall life of the battery but that’s to be expected. No onboard charging mechanism reduces the total size and weight of the flashlight making it pretty portable. 

Color and LEDs 

The emitter on the Emisar D4V2 is the Luminus SST-20 4000K which may not put out as much light as the XPL-HI but it definitely gets the job done. 

The lights come in a variety of colors including:

  • Black
  • Gray
  • Cyan
  • Sand 


There are also a number of LED options including: 

E21A warm white 2700K – a yellow high CRI light that will offer the most benefit at night. It’s a bright white that offers a lot of power but again, sacrifices in output. 

SST-20 4000K – This is a cooler bright white light that might give off more of a blue color but is still high CRI. This is the ideal color that most enthusiasts would be looking for. 

There are also a series of smaller auxiliary LEDs around the edge of the flashlight lens. There are about 8 lights that can display up to 6 different colors. 

With these auxiliary LEDs comes 4 options. You can have them on low, high, blinking, or off. The high level is nice but it’s very bright and the low level might be a little too low. 

The blinking mode is something that we feel is almost unnecessarily thrown into a lot of these designs for no particular reason at all. You’ll lose battery life faster and we can’t imagine that anyone would want to use a blinking flashlight for any particular purpose other than to maybe alert someone that you’re coming in the dark.

Build Quality 

Emisar is well known for being one of the best flashlight manufacturers on the market today so we constantly have high expectations from the build quality down to the beams and light output. 

Let’s start with the incredible detail on the knurling of the Emisar D4V2. It has a square feel to it and provides great grip on the fingers. The magnetic tailcap has vertical lines that also provide a great amount of grip when you’re opening and closing it. 

It features a stainless steel textured bezel and we’re not sure if that was done on purpose or not. Either way, it provides a nice contrast from the body. 

The lubrication of the threads is ideal and while there are no water or dust resistance ratings on this flashlight we believe that it would hold up well against water or contaminant damage. We don’t believe it could survive an entire submersion but is definitely water resistant. 

The Anodisation isn’t incredibly smooth which again, provides that textured feel that gives you a solid amount of grip without being too much. After looking through a few of these flashlights we can also determine that the design quality and build is consistent across the board. There aren’t very many discrepancies from one LED flashlight to the next.

Ease of Use 

Operating the Emisar V2 flashlight is simple and the electronic soft touch button is easy to push but designed and positioned in a way that prevents accidental triggering. 

The knurling off the flashlight makes it easy to hold and while it’s on the small side, it has a decent amount of weight to it. 

The belt pocket clip serves as a nice additional feature that makes it easier to store the flashlight conveniently for easy use. Opening and closing the flashlight is simple due to the properly lubricated threads and overall using the flashlight is incredibly easy and simple for a more affordable option.

The one thing that takes this flashlight down a notch on the “ease of use scale” is how many features are packed into the basic user interface. It comes with a lightning mode, candle flicker, and strobe feature. 

One click is what you need to get it to turn on. This will put it on the last brightness level you used. 

If you click and hold it, it’ll ramp up the brightness to max and then the light will start blinking once you’ve hit the max. 

Releasing the button will leave you at the brightness level you were at when you were ramping up. 

Once you hit the top again and hold down the button it will start ramping down. This is where we come in with the “unnecessary” but cool features. 

There is a double click feature that immediately takes you to the brightest setting or lowest setting depending on where you are when you hit it. Double click will also adjust to the various unique features like flickering, lightning, and strobe.

Final Verdict 


  • Very bright in a small flashlight
  • Cool auxiliary LEDs
  • Loaded with custom options 



  • Runs hot
  • Ramps down very quickly

What more can we say about this little flashlight? The Emisar D4V2 is a great hotrod that pushes out a lot of light, comes with some unique features, and looks great. The high beam modes are bright as could be and the low beam modes offer a steady and subtle stream of light that preserve battery power but still light up the room. 

The auxiliary LEDs are a fun addition and while there might be a lot of unnecessary features in here, we still believe that they’ve done a nice job keeping the flashlight compact and affordable.
