Emisar D1 Flashlight Review


Another Emisar light!  This one I paid for myself, after liking the D4 so much.  I like the idea; let’s see how the execution is.  Since the build is so similar between the D1 and D4, this review will probably be a bit abbreviated.

Official Specs and Features


There are three (or four?) colors available.  And only one emitter (Cree XP-L HI) but two tints.


Like the D4, this is $40, with some different cell tubes available too.

Short Review

While the head is a little big for pocket carry, this is an excellent light with a wonderful UI.  Easily recommended.

Long Review

What’s Included

  • Emisar D1
  • Spare o-rings (2)


Package and Manual

Simple cardboard box, with a sticker.


There is no manual.  Here’s a flow chart (from mtn) of the UI:


Build Quality and Disassembly

Just like the D4, the build is great.  My biggest complaint is that I don’t think the greens match between the head and tail, and body.  The center seems lighter.  Minorly annoying.


The head and tail come off easily, but the driver et al will provide some difficulty to remove.  It can be done, if your attitude is right.




  • Dimensions: 105mm(length) * 35mm(head) * 24mm(body)



The head is big enough that it doesn’t ride in my pocket easily.  Doesn’t mean I don’t try, though…


This page [is] intentionally left blank.


The D1 uses a single 18650.  I tested this light with a 25r, but with a beefy spring on both ends, and long threads on the body, any type 18650 should work fine.  You’ll want to use a high quality cell for best output.

After the D4 killed one of my cells, I was leery to do a runtime test.  But this test went fine.  At about 23 minutes I checked the cell voltage and put the light back to turbo.  Note that it didn’t reset to full output. The light did get warm, but never really hot, to hold.


User Interface and Operation

There’s a single side e-switch, on the head of this light.


I’ll refer to the flow chart for the UI, which is very comprehensive.


Note the special modes at the bottom – this is a very versatile, feature rich UI!!

LED and Beam

The emitter of choice in this light is a Cree XP-L HI.  My variant is the V2 3A tint, and I couldn’t be more pleased.  I love XP-L HI’s and this is no exception.


The beam is throwy, but the spot is very even all the way across.  Not like a typical thrower (TM38, or C8 for example) where all the light seems to converge to a point. With the D1, the light all seems to converge to a spot, which is even all the way across.

Random Comparisons and Competitive Options….

The most compared light to the D1 seems to have been the Zebralight SC600 mk III HI.  I have both of these lights and there’s really no comparison.  The SC600 fits in the pocket easily.  Build quality is better.  I like the UI better on the 600…. Overall the SC600 is much preferred, but it’s also over twice the price.


What I like

  • Throw
  • Build quality
  • Color options
  • Emitter choice

What I don’t like

  • Body doesn’t match head and tail perfectly (it IS close)
  • Head’s too big for easy pocket carry
  • No means to carry (lanyard/clip) are included.

Up Next

Nitecore EC23 is next, possibly even today!
