I had my D1S about a week over Christmas before I travelled abroad for work, the D4 came with me as my general purpose/EDC light.
Hopefully I will get a chance to stretch the D1S legs when I get back home!
I wish there was a high CRI version of the D1, I would order it in an instant!
Waiting for a D1 and a D1S to arrive soon. I have 2 D4’s already.
These are great little lights.
It uses XP-L HI, not XHP35 HI. They do look pretty similar though.
XP-L HI is flat with a particular pattern of dots, with a bump 90 degrees from the lead wires:
XHP35 HI is larger and more splotchy, with a bump 180 degrees from the lead wires:
It’s mostly distinguishable by the crosshair pattern between its four individual dies, which is more easily seen while the emitter is on:
I shine lights through an old projector lens to get a better magnified view of the emitters. It’s a lot easier than trying to look directly at the emitter while it’s on.
Great detailed review. Thank you!
Got my Emisar D1S today in grey and a Nitecore SRT9 and a blue D4 is in transit to me too so the Emisar family is almost complete.
Hey tk, you are right… it is xpl hi… those factory dedome leds look very similar and I got confused. Lol
I don’t know if this has been discussed yet but I would love to see a D1S with 20700 battery tube, which makes sense for this light, and maybe 22mm driver room so we can mod it with XHP35 HI and 1.5A boost driver from KD.
It will be cool if we can mod d1s to xhp35 hi… however, you can purchase acebeam L16 for $60. ( online deal )… i got one back in december. I dont know if coupon still valid… L16 is little bit smaller than d1s, and longer…
Anyone know a holster for D1s?
I am thinking of getting one of these to supplement a floody headlamp. I’d like a holster to hold it on the shoulder strap of my rucksack so I can easily grab it.
A lot of holsters have webbing strips to thread your belt through. If your backpack strap has a webbing strip running along the strap, you can use a connecting clip to attach the holster:
These clips are only relevant if the webbing strips to be connected run parallel to each other. Webbing strips that run at 90° to each other need a different solution where one of the strips has a pop stud / velcro / somesuch, so that you can thread one strip through the other, then secure it with the pop stud. Caveat emptor - not all belt holsters can be threaded that way, some of them have their webbing strips permanently sewn down at both ends.
Thanks Phlogiston, those look really neat. Now, I just need to find a small lightweight holster.
Wanted to say I just received the optional 18350 shorty tube in the green and 2 Windyfire 18350 IMR cells from mtnelectronics. I have to say and as always, their service is outstanding.
My green D1, (which I also received from mtn), has the smooth finish and the shorty 18350 tube has the rougher texture which some here don’t care for. I have to admit, I prefer the smooth finish but the rougher texture of the shorty tube is in the center of the light and adds a little more purchase to the now tiny light. Also, the rougher green 18350 tube matches the smooth green finish pretty darn good.
What I’m trying to say is the D1, (mine is CW which I favor and the D1’s CW beam is the best I’ve ever encountered), is already outstanding and with the addition of the shorty 18350 tube, I just love this thing!
The “bump” offset to the bond wires is an anti-static wire. 
Also looking for a decent holster!
I’m bored with my D1, wonder if I can fit it with 4 20700’s and an XHP-35?
Sure you can. Just not all at the time. Actually you may have to split the batteries into smaller pieces.
Your D1 might have to be bored too, if you want to run a 20700 cell in it. :laughing:
Building a battery pack for 4 of them would be possible, but it would look pretty silly and wouldn’t use the space efficiently.
Does anyone know why nichia 219c option is available only for D4 but not for the D1 or D1S? Seems the hotter 219C would be more fitting in the D1 and especially D1S with the much larger thermal mass.
Being throwers, the XPL-HI makes a much better job “throwing” the light. Maybe with the Nichia it would enlarge the hotspot, but it would not reach so much in distance probably!
I guess the heat is not a problem on those 2 lights, but the function of “throw” would probably suffer some decrease with that LED. Even if the tint would improve!
