Did it come off cleanly? That would be much easier indeed except I’m not 100% sure about it.

Oh yeah it comes right off, though the DC-FIX is trash after that; one time use only.

i only ran it for like 4 minutes so i’m not sure how it affected the beam overall

Thanks. Will try it once the light gets here. I’ll try to take pictures too.

Overall I love the new firmware! I love the new stepped ramping. Good job ToyKeeper. Thanks for all of your hard work.

I do have some feedback after using it a few days. The most annoying feature is not being able to exit momentary mode without pulling the battery. I understand why momentary mode has no exit. In my opinion it should take more than 4 clicks to activate it since the mode has no exit function built in. Because of timing idiosyncrasies I always seemingly activate momentary mode instead of lockout when the light is off. I find that I have to slow down my clicking. The fact that I have pull the battery to exit is frustrating, at least this is open source so I am going to reflash it with some changes.

The other other feedback that I have is that it takes longer for the light to turn off when in ramping mode. I guess because it is waiting to see if there is any more user input? But the delay seems oddly long.

I appreciate the flashing breakout being accessible.

Current on Turbo was everything between 11 and 18 Amps on turbo. It’s highly dependant on how hard you press on the battery while measuring. If you have short cells, I could imagine you’re missing out on quiet some current. Guess a bypass would be beneficial.

Is double click turbo affected by my ramp ceiling? I didn’t press anything when setting the ceiling, so I assume it’s on maximum? Well if I double click from off and then double click again when it’s on, it gets a bit brighter. is this intended? I thought turbo is turbo. Edit: This just happens with the stepped mode, on ramping double click is full power directly.

The V3 UI fits on the D1 and D4, but if you’re going to flash them, you may as well upgrade to Anduril. It’s what I use, at least.

I also find it inconvenient that momentary is 4 clicks and lockout is 6 clicks. This is fixed in Anduril, which uses 4 clicks for lockout.

If you feel the click timeout is too long, change a couple of definitions and re-compile the code. Specifically, change these:

#define HOLD_TIMEOUT 24
#define RELEASE_TIMEOUT 24

Each unit (tick) is 16 ms, so one second is 62 ticks. Higher values make it easier to enter long sequences, lower values make the entire interface respond faster.

Double-click from off goes to the current ramp’s ceiling.

Double-click while on goes to full turbo.

In config modes, if you don’t press anything, the value is not changed.

Each ramp has its own ceiling and floor.

It’s a nice design but i lost the wow factor for brightness. My eyes are use to lights with >16k lumens

I hope you weren’t expecting 16k lumens from a light this size with a single battery, especially without active cooling. The tech for that doesn’t even exist yet.

Thanks for the link! Which of the 5 available would be best for flood? These should fit the D4S no problem?

Ah nice thanks for the explanation. Then I correct myself on the maximum current for the XP-L Hi version to be between 16.5A and 18A on a Golisi 4200 cell.

So maximum ceiling in config is reached by pressing once during ceiling setup? Seems like in stepped it’s lower than in ramping.
And how do I reach the 3×7135 mode in stepped mode? Also with twist off and on?

Let me thank you for this great piece of UI. Just had the flashlight out with me. It’s just such a pleasure to use. I need more of them.

Yes, but it’ll go to the nearest configured step instead of going exactly to the 3×7135 level.

Hi JordanZHP, I think C12288_ANGIE-W would be the best for flood judging from the 37degree viewing angle.

kept trying to compare, on a white wall, my new green D4S XP-L 3A to my grey D4 XP-L 3A….no way Jose!
I had to get out my Q8 to approximate the throw and brightness.

Me like 2time at least!

well, the protected 26650 in my Rofis MR70 will not fit in my D4S (too long)
butt I can charge the Shockli IMR26650 5500mAh from RMM in the MR70 just fine
and I can use either in the MR70 to charge anything using USB for recharge
very handy and useful

I can’t speak for vendors in other countries, but after doing some Googling it looks like all the U.S.-based vendors are out of stock, and most list a 6 week lead time.

This might be a good thing for intl-outdoor or Mountain Electronics to stock…? I’d almost certainly buy one from them (assuming the cost of shipping weren’t $8 like Mouser. Tired )

I want a cool white light about as much as I want Cool Ranch Soda.

this D4S throws just as far as my Klarus XT11GTXHP 35 Hi! I’m new here so forgive my ignorance. I showed a buddy at work my newly acquired D4S and he instantly bought one yesterday from mtn! Toykeeper, I could see the smooth ramp function on this light alone selling Big to the general public! My wife’s mom thought it was.. and I quote, “a really nice mood light” lol. 

Now the momentary tactical mode In my opinion is perfect! I love that it cannot exit this mode without untwisting the tailcap for a set amount of time. This is truly a re-invention of the modern day LED flashlight. This light is actually fun to operate and learn all the modes too with the flow chart!

It’s a better mood light with Anduril installed. That adds, among other things, candle mode. Works well with a traffic wand or something over the bezel.

Also, for the pinouts, this might help. I refer to it while figuring out where to poke wires through my D4S driver.

@ToyKeeper
How do you feel about these arguments for an estimate of levels?

./level_calc.py 2 150 7135 1 0.5 400 FET 1 10 4300

ToyKeeper, thank you! These holes in battery side driver used by acupuncture-style with a set of six pins ? Six holes for six pins for easy flashing firmware without disassembly the head?

Yes.

It’s a bit primitive, but it works and it uses parts which are easy to get.

You should be able to check the accuracy by comparing known levels to what the computed ramp says. For example, level 85 is the 3×7135 mode and should be about 400 lm with XP-L HI emitters.

I’d suggest checking a few points along the curve, like 1, 40, 85, 120, and 150. Then adjust the parameters until all of those line up with the expected values.

Because the calculator and the actual light won’t necessarily agree, it may be necessary to split the ramp into two parts and calculate them separately. Probably levels 1 to 85 in one segment, and 86 to 150 in another segment. It’s a little tricky getting the calculated shape to match, which is why I haven’t already made a reference chart.

Additionally, the 219c curve will be different because all its FET values are multiplied by 0.8. This is because Hank was getting complaints about 219c emitters burning themselves out on turbo, so the 219c “turbo” is 80% power.

I’ll try this.

How are the discrete modes in the actual firmware calculated? Sorry if I missed that, if it’s already written somewhere.

They’re evenly-spaced along the ramp. Floor at one end, ceiling at the other end, and “num steps – 2” levels between.

Because a few people have asked, I added a stepped ramp calculator called “steps.py” in the anduril directory. Here is an example of its usage:

> ./steps.py 1 150 10
1: 1
2: 17
3: 34
4: 50
5: 67
6: 83
7: 100
8: 116
9: 133
10: 150

Or, using the D4S default values, here is the result:

> ./steps.py 20 120 7
1: 20
2: 36
3: 53
4: 70
5: 86
6: 103
7: 120

Another solution until the pogo pins arrive: just use a piece of breadboard with some crooked pin headers as the programming vias are not aligned on a 100mil grid.
It may not be the best solution, but it’s faster than connecting all 6 pins seperate each time.

Adapter for the D4S is on the left, Clip for D4 / Q8 is on the right.

Also, if you don’t have an AVR ISP but own an arduino you can program the arduino to act as an ISP.

You are so great one! It works without any desassembling!

Do you plan to add OFF-timer? It will be great, believe me. One minute = One click. Could you make sub-menu for this timer? Is it possible?

I love the timer feature on the Olight S1R. If Hank could give us a diffused side light, motion sensor and timer in the D4GT I’d have his baby.
