Ah I see. Makes sense.
It will burn up with that DD ‘driver’.
With 4 in parallel they will survive better due to internal resistance of the battery and the consequential voltage sag.
Derisive quote marks not necessary, but yes, running a low-Vf emitter direct-drive from a high-amp cell will generally turn the LED into smoke.
Even without that though, the XP-L HI is better for throw purposes… and the reflector is optimized for a flat emitter so the focus would be off a little with a domed emitter.
That’s a serious problem. We know what happens when you get bored. 
D1S with shorty tube, I added a spacer, works fine.
My D1 does not agree with you since I put an STT40 in it :partying_face:
Still much cooler than my 219C D4 but it gets hot fast now !
Next step is to put a dedomed XP-L in the D1S to get full throw !
De-dome the SST-40 X3, or slice it (much better success rate slicing)
My D1 is bored for the 20700 cell and uses an XP-L2 at over 2000 lumens, my D1s is using a sliced and diced XM-L2 for better throw and it too is just over 2000 lumens. Betting I can make a 26650 tube for it though. (26350?)
The D1S is no longer available in blue or green? I didn’t bought a light since a long time but the video review by Advanced knife bro got me intrigued.
The D1S has only been offered in black or grey so far. Has anybody noticed voltage readout inaccuracy? Mine consistently reads .2v lower than actual voltage.
My D1s reads spot on, but my D1 & D4 both read .1 volt under.
On the picture the grey version is a little bluish (at-least on my monitor).
Will there be a green version in the future?
You mean sst-40 ?
Looking for user who can write Emisar D1 firmware, simple 3-4 modes, temperature controled
I just got the green version of the D1. I can’t believe how beautiful it is. Makes me want to collect all the colors of the Emisars now.
Green is the color I had wanted for an Emisar but unfortunately I’ve been reading complaints the (new textured) green color coating is not durable and wears off easily. (is it even anodize?) So now I’m not sure I want it, that has delayed my decision to buy an Emisar altogether until I look into that first.
^ My green D1 is smooth. Ordered it mid-January.
I think the grainy finish is only on D4.
My D1 is smooth green and finish looks perfect. I didnt know the D4 green had rough texture. I thought only D1s had rough textured surface
That already exists. There are several different D1-compatible firmwares which could meet that criteria.
So for the green color the D1 is smooth finish and the D1S and D4 both are texture finish?
Can someone please confirm if this it correct or not?
You can get the latest status by going to Intl-Outdoor.com and checking whether it says “smooth finish” or “grainy finish” next to each color.
