Hmmm. Mine is still processing. I wonder if I should be concerned, or just wait patiently.
DQG Tiny 26650 3th, I think it still entitled to the world’s smallest single 26650 light.
Hard to go back to “normal” lights with a piece of magic like this in your hands.
UI, form factor, performance and “wow!” factor so satisfying.
Love the blue LED “trits”…nice touch!
You are so right. I’m seriously contemplating only buying emisars from now on. I just wished that they pushed up production of more colors, models, and cool add-ons like the blue LEDs.
How can i change stepped to smooth ramping ?
when light is on…fast click 3x…
Thank you… i spent 5 minutes trying to switch to smooth ramping… i was doing three fast click and hold from off…
I tested three unprotected.
1st. Shockli imr 5500 mah. 5040 lumen… turbo output maintain strong.
2nd. Liitokala 5000 Mah… 5000 lumen…
3rd. Efest green imr 4200 mah. 4750 lumen.
I am using shockli imr on my d4s… it performs great…
I did some research on 26650 high drain batteries not long ago:
I’m curious what people think of the method used for smooth and stepped ramps, and switching between them. Do you use just one, or both? If just one, which? What configurations do you use, and why?
Smooth ramping is nice just for the pure novelty of it. I guess when I use a flashlight it’s just to light something up in the dark that I’m looking for or to get a better view. Very seldom, if at all, do I need to change the level of light for the few moments that I need it.
Magical lights like these are more show pieces for me and my friends. I can look in the closet with anything. I am almost reluctant to use my showcase lights for fear of damaging them by either a clumsy drop, banging it on something or rattling my keys against it all day.
Mostly I just appreciate all the options and the complicated UI for the craftiness of the programmer and the effort it took to make it work well.
The 219C D4S does exactly what is specified. I got 2930 lumens at turn on (actually at ~2 sec taking into consideration the measurement time). This was with an iJoy 4200 mAh 26650.
My D4 actually does a bit more than that at 3170 lumens with a VTC5A, but it’s the earlier CRI80 version with the more powerful driver. It also steps down after ten seconds while the D4S is still at 2430 lumen at 30 seconds.
D4S
0:00 2930 lm
0:30 2430 lm
1:00 1800 lm
1:30 1253 lm
2:00 979 lm
2:30 836 lm
3:00 808 lm
Would someone measure max regulated (7135) output for both xpl hi and 219c versions?
Please and thank you!
I know the feeling. When trying to break out of my routine I’ll almost grab a light and think “It’s too nice to take to work!” I work in a greasy, oily, swarfy environment.
Trying to master flashing so I can put TK firmware in ALL my lights (where possible).
Per Mooch, as of April 11, 2018, iJOY, Golisi, Vapecell, and Aspire all use the same cell under the wrap ~30A-32A/4200mAh-4300mAh.
The red/black Shockli 5500mAh was estimated at 20A.
Stepped ramps mode is a nice feature to have… now i know stepped and smooth modes are interchangeable by three fast clicks.
Smooth Ramping modes is for around the house.
Stepped modes for outdoor.
Emisar is ahead of their game. One of my favorite feature is magnetic tailcap…
I’ve just tried the stepped ramps and will probably stick to that. Feels awesome and I love that you can choose the number of steps.
And the fact that the light always (after a moment of not clicking anything) ramps up by default and you can just go down with a double click and hold is great. Even though this causes the 0.5s delay before the light shuts off after clicking. I can live with that since the reversing is too handy!
I’m not a fan of the Zebralightesque “accidentally went too high from off” syndrome. With the D4 there was a small delay when you held the switch down from off. The light turned to moon and you could release. On the D4S you’ll accidentally activate the memorized mode if you release the switch too soon. This can happen easily since the light turns on moon immediately when the switch is pressed. You have to time it correctly. Also the moon always coming on first when clicking the light on feels weird.
Ok. After playing with the light, I like stepped mode ramp better… it’s so cool. Turbo mode can be activated by double click… I am going to stick with stepped mode…
I can also attach my magnetic tailcap to the garage when I am working on the car… no more rolling!
I think it’s the best stock Hot Rod light I ever purchased for the money. I can’t seem to stop playing with it or having it out of reach for some reason, Crazy huh?
Fits in one of my holsters well, but I don’t want to take a chance on scratching it. Heck I’m not even going to mess with it and bypass the springs, it’s that remarkable to me!
TK/Hank you hit this one is out of the park, outstanding job! :+1: Thank you! 
I ordered from Intl-Outdoor, and my green, 219c, D4S arrived at my house (in Seattle) today. Now to learn the UI a bit.
It’s hard to appreciate brightness, since I’m sitting outside on a clear day, but it’s definitely bright, and hot.
