I must be dense… I see only the selection of one color of aux led.
The aux led is under the UI option as mentioned by wolfstyle

I see now, not just a cost to flash the new firmware, but that also includes the leds!!! Is not very clear on the selection page, since there is a place to select the aux colors.

EDC rotation:
FW3A, LH351D 3500k
FW3A, SST20 4000k
FW3A, Nichia 4000k sw40 r9080 (favorite light!)
Emisar D4V2, SST20 4000k

Close, but not what I’m seeing.
Dropdown 1 – choose body color
Dropdown 2 – “IOS V3 UI” /or/ “Anduril UI (the same aux LED function as the D4v2) +$1.99”
Dropdown 3 – LED selection

Then some checkboxes for Aux LED colors.

Nothing here says the checkboxes are only for the Ramping OS V3 or that choosing Anduril gives you RGB.

So… Is the RGB AUX hardware in ALL new D4S but hardcoded to a specific color if you choose Ramping, or is a different LED/Aux board put in if you choose Anduril?

If you choose Anduril in the 2nd option, just omit the third option. Otherwise it’ll be the old style single colour aux led if IOS V3 UI is selected.

Maybe Hank should just consolidate the single aux led options in the third option to the second one for better clarity.

…E07 is more EDC friendly than D4S and they have the same head diameter…

True, the E07 is an excellent light, very slim and lighter than the D4S. However, I much prefer my D4S which I comfortably belt-carry in an old Thrunite TC20 holster.

The E07’s light weight means less mass to cope with the heat buildup while pumping out all those highly advertised lumens. Also, its extreme flood beam can’t compare (IMO) with the more focused projecting beam of the D4S. Even with SST 20’s the D4S still is the best combination of throw and flood of any light of its size that I have ever owned or heard about.

Without doubt, the D4S is a mini-Masterpiece!

Ok, lets start with RAMP_LENGTH. This defines how many levels are available.

After that, you have PWM1_LEVELS and PWM2_LEVELS.
For that, you need to know, that each output (3×7135 or FET) can be set between 0 (off) and 255 (full power).

Now PWM1_LEVELS defines the output of the 3×7135 for each level while PWM2_LEVELS defines the same thing for the FET.

There you will see, that PWM1_LEVELS keeps increasing until it’s 83rd value (level 83). At level 83 it is set to 255 so the 3×7135 now are running at full power.
That’s also why MAX_1×7135 is set to 83. This tells the driver to start at level 83 when the battery is inserted as lvl 83 is max. regulated power.

After level 83, you can see that the 3×7135 channel is kept at 255 while the FET keeps increasing.

If you take a look into the FW3A config (FW3A uses a FET+1+7 config), there you see that PWM1_LEVELS is for the 1×7135, PWM2_LEVELS is for 7×7135 and PWM3_LEVELS is the FET.

this was a good starter for me so i added some comments to help me understand. What is the maths involved to get these integers in the PWM1_LEVELS? If I wanted to cut PWM on FET to 80%, would my end value be 204? I see 128 for 219c on fw3a so 50% PWM (a bit conservative imo, so id like to increase pwm to 80%)
