Emisar D4S review

You will get it tomorrow… it just take longer to ship from southern california…

Just hope you don’t hate your new D4s…

Nope… never… intl-outdoor knows how to make blf guys happy…

What light is the second from right?

Please disregard the old test… here is d4s xpl hi 5000k with fully charged shockli 26650. It is pushing 5000 lumen.

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.
