Emisar D4S review

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! :beer:

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.

Very nice… I like stepped mode and the mode will go to high max ( 50 % ), unless you double click…

I’m glad to hear people like most of the new stuff. I haven’t gotten much feedback about the stepped ramp yet.

This is the first negative feedback I’ve heard about the instant moon feature. If you’d like to disable that, comment out this part of the code:

    // hold (initially): go to lowest level, but allow abort for regular click
    else if (event == EV_click1_press) {
        set_level(nearest_level(1));
        return MISCHIEF_MANAGED;
    }

So, everyone, what do you prefer?

  • A. Activate the lowest level immediately when the button is pressed. Provides a hint that “click” and “hold” do different things, but requires the user to time the button release without direct feedback. (RampingIOS V3, Anduril)
  • B. Don’t respond when the button is pressed. Takes longer to get any light, but makes moon timing easier. (RampingIOS V2, NarsilM)

Basically, what do you prefer for step 1 here?

  1. At button press…
    • A. … turn on at the lowest level.
    • B. … do nothing. Stay off.
  2. If user releases button quickly, go to memorized level.
  3. If user holds the button for 0.4s, lock in the lowest level. User can release the button at this point to stay at the lowest level, or keep holding to ramp up.

Hello!

Happily, just pulled the trigger on 2 D4S, grey 219C and Green XPL HI 5000K NW from MTN.

I was considering the XPG2 5700K version, but budgetary limits kick in. Would anyone help describe the differences between the XPL HI NW and the XPG2 S4 2B: tint artifacts, throw and output differences, runtime?

Any and all opinions and recommendations are welcome, as I am a long time CW bias recently converted to NW and high CRI, seeking the knowledge of others with experience.

Also, decided on the Shockli 5500 mAh cells, any other recommendations?

Many thanks in advance for your input !

Shockli is the best 26650 I can find…

I have no D4S, but from the reading I tend to B.

Is there a way to calculate lumen for the stepped ramp?
With the known max output, no. of steps, steps for top and bottom ceiling?
I think of a spreadsheet, you type the values in and get the lumens for each step.

Ish.

It’s hard to do because of how different LEDs have different lumen levels, and in the FET modes, it also depends a lot on battery type and voltage.

Aside from that though, basically you’d have to look up the PWM values from the firmware’s ramp table, calculate the power level, then look up that power level on an emitter test graph.

Or try the bin/level_calc.py tool, which produces a relatively naive estimate of how many lumens it expects. These numbers may not match actual measurements though, because it doesn’t know the emitter’s response curve and may have been given intentionally wrong values in order to force the graph into a particular shape. Like, for the D4S, I told the calculator the lowest level was 11.2 lm and the highest was 4000 lm, and that it should use a ninth-root curve shape, because this got the values to line up how I wanted. But in reality it’s more like 0.3 lm to 5000 lm.

Ish would be enough.

I meant per light. Not in general for all FSM lights

Fw3a and D4S
As battery a 30Q.
Data for discharge from HKJ.

Hm, it sounds already complicated.

how about the black Basen with gold writing…it has 60a pulse

I have an authentic basen 5000mah with 50/60a pulse. there’s also the basen 4500mah with 40/60a pulse. have you checked those? I don’t have your set up to check the specs in the light itself. I almost bought the 4500 but it doesn’t have Basen written 4 times on the top of the battery like my other one does

Where can you purchase basen 26650?

Stepped ramp modes for xpl hi 5000k. 4, 34, 110, 246, 481, 1016, 1906 lumen… number will depends on the battery… atleast we get an idea…

Awesome…thanks for that…I have the same emitters.

What happens if change the stepped ramps to like just 2 steps? Does it just split the output in half?
