My 219c 5000k is from December. It has some green from moon to 1x7135 (only if you see it in comparison with other white/rosy tints on a white wall) from around there and up to turbo is a nice white.
Just received my silver/white D4 directly from Hank. Took 17 days from day of order . My first Emisar and loving it. The more I use side switch lights the more I think they will be the only type I buy from now on , especially with ramping. The UI is perfect and the thermal step down works flawlessly. Being able to get momentary on is also a plus. Tonight I get to put it through it’s paces if it would stop raining every single day. Emisars are actually more attractive than pictures do them credit. I see more in my future. 
The HVAC pics are a tough situation. Needs to be small for insertion and control, yet needs to make enough light for a demanding job, while not getting hot or stepping down. Most of the lights that can produce enough light to do this will step down in short order, or are too large for the situation. So I’m thinking the D4, the new D4S, or the DQG Tiny 7 XP-G2 lights are probably more inline with this odd situation. The new D4S will have the large cell and some programability, the DQG might get too warm and at higher levels will step down, maybe too soon. The D4 at the necessary power levels will probably get too hot.
An Raysoon F13 modified triple with CUTE-3 also uses the 26650, can be fit with a nice heat sink, would offer output and run time with program options through firmware selection, but of course this would be a build and not a readily available light.
Mateminco has a triple X6 coming out, quite floody, makes around 3000 lumens, can run quite long in the 6th of 7 levels without getting too hot, might be a likely candidate as well. Run time would be more limited due to the smaller cell size (18650)
Sofirn C8F triple? Decent price, not too large, in the 3000 lumens vicinity. Tends to be more throwy than the Mateminco X6 at similar output levels, both use the 18650 cell.
Emisar D4S
Sofirn C8F
Mateminco X6 triple
Check those out Zamar and see what you think, none of them should be extremely pricey, all are worthy fairly high powered lights. The Mateminco might not be available just yet…
Thanks again. What battery makes & models do you recommend for these flashlights? Are they sold anywhere on cheap? Some 50mm diameter flashlights I seen require 4x18650 batteries. Are these any better for my purpose than 1x18650 flashlights above, and which models?
Hello,
I have Emisar D4 and I have a question.
I took a photo of the reflector on lowest light settings and it looks like this. There are some scratches (marked green) and something that looks like dust specks (marked red)
I wonder mostly about the scratches, how did they get there and is this normal? And I know it is just a tiny detail, it doesn’t bother me too much…
Also my temperature readout is way off, showing 15 degrees more. But I’ve read I’m not the only one here 
As far as scratches goes I can’t help. As tar as the temperature setting goes you likely need to recalibrate. From page 1 of the thread,
10+ fast clicks then press and hold: Thermal config mode, added in v2. Hold the button until it gets to the action you want:
Blinks out current temperature limit. Release button to exit with no changes, or keep holding to continue.
“Buzzes” for 2 seconds. Release button to set temperature limit to maximum, or keep holding to continue.
Light goes to turbo. Hold button until the light feels hot enough, then let go to set a new temperature limit.
If you are adventurous you can put we firmware like Anduril
Yes, I’ve had it recalibrated already. Its now set at 65 and given the limit is 70, there is not much leeway left for higher settings. It would be nice if there would be higher limit. Or a more precise temp sensor.
I’m adventurous but I know myself - once I disasseble something its never the same again… And not in a good way 
I don’t believe ( others may correct me) but I don’t think you can set the temperature with the original firmware. But once you set it up the way you want there’s no need to change it again.
If its not working for you then you need to change firmware or get a bigger light.
You can not set it precisely by clicking a button (like you can on Andúril firmware), but after the calibration it blinks out the new setting. And mine blinked 65
Seem like your set up fine for now then. Hope you enjoy your D4
Yes, it’s a really nice flashlight. Anodizing is flawless, machining is perfect and the amount of light coming from it is just mindblowing. Can’t wait for winter, it will be a great hand warmer too
Can NarsilM be loaded in the D4?
Normal and essentially inconsequential dgq3, you’re going to find virtually all the optics have such markations from the molding process.
Don’t worry too much about the temperature readout, set it for what you can handle and the light will be fine. The electronics can take FAR more than you can. The difference between the readout and your means of measuring the external case are both going to have some variance, this can add up to what seems like a lot, but it’s still all about not burning your hand, so just take care of you and all will be well. 
I dont know this has been told… sony vtc5a is great in the d4… i mean vtc5a beat vtc5 by big margin…
Emisar d4 xpl hi 6500k
Sony vtc5a 4000 lumen
Sony vtc5 3600 lumen
That is why I smartly measured the difference at ambient temperature, when the light was cold
And it’s kinda like a waiter getting used to handling hot plates, I can’t stop playing with it and can already feel my hands hardening Maybe in a few months I could add 10 degrees, but the light can not. Well…whatever, it’s not a real issue anyway
The “scratches” or striations you marked look to me like the result of turbulence and minor temperature variations during the molding process. I’d guess they are inescapable, and baked in to the original design & specification.
Yeah, sorry, the D4 doesn’t have a way to calibrate the sensor. It only has a way to set the maximum temperature.
The D4S fixes this, and I made the D4S code also work on D4/D1/D1S, but I don’t know if Hank will update older models with the new V3 firmware. It would probably need more testing and maybe some tweaks before it can be considered stable on the older models. In particular, thermal regulation settings require hands-on testing with fully-assembled lights, which is time-consuming.
But I run Anduril on literally all of my Emisar lights, and it seems to work pretty well. I don’t use turbo long enough for thermal regulation to be needed though.
Yes. Just don’t rely on its thermal features, because they’re designed for hosts with a much lower power-to-mass ratio. NarsilM should work fine on the D4 as long as you regulate heat manually.
The Q8 config should work without any changes. I think its voltage readout might be off by 0.1V though, due to a difference in diodes used on the two models. I see in my configs that the Q8 has a fudge factor of 0.35V, while the D4 uses 0.25V.
Can anyone tell me what the mid way flash signifies in the upward ramp?
