A lot of things have changed recently… below is a summary:
Ramp stuff
Better low + high modes
Smoother, slower ramp on lowest levels (uses pulse frequency modulation combined with pulse width modulation to get higher resolution while generating control voltage signals for the current regulator)
Faster moon activation from off, with adjustable “jump start” correction factor.
Eliminated (or at least greatly reduced) audible sound when DD FET is at 50% power on Linear+DDFET lights.
Faster auto-reverse on 1H for ramping up/down, because the old timing was too slow.
More configurable options
Smooth ramp speed (can slow it down)
Choose whether hold-from-off should ramp up or stay at moon
Select turbo style, one setting for Simple UI and one for Advanced UI. Three styles available:
No turbo: hard limit at ceiling
Anduril 1 style: 2C while on goes to full power
Anduril 2 style: 2C while on goes to ceiling, unless ramped up to ceiling first, which would go to full power
Misc stuff
Auto-lock can work in Simple UI if configured that way.
Easier to enter large numbers in config menus. During a number entry prompt, click for +1, or hold for +10.
Faster thermal regulation on 3-channel lights like D4Sv2 (FET+3+1) and D18 (FET+13+1).
Made party strobe flashes more consistent.
Fixed corner cases in hybrid memory (manual memory with a timer).
Tint ramping…
Support for tint ramping on D4S and KR4. Can also work on K9.3 and D4.
Allows “200% power” turbo with both tints running at 100%. The color space for this is shown below, shaped like a house. Can also use DD FET on one channel, but it’s usually not a visible difference.
User can choose tint-ramp or tint-toggle. It’s in the hardware-specific config menu (Advanced mode Off 9H).
Fixed occasional flicker on inactive tint channel.
Enabled middle tint at moon level.
On tint-ramp lights, the user can ramp in two directions: Tint and brightness. These are mostly independent of each other, so brightness remains steady while changing tint, and tint remains steady while changing brightness. However, when going above 100% power, this is not always possible. Go bright enough, and it hits a roof, basically, and then must ramp toward the middle tint in order to get any brighter.
So now the color space has a floor, a ceiling, an attic, a roof, and a peak. Please don’t ask me to add a patio.
Depending on how things go, however… I might have to add a chimney. This would allow the DD FET to be used by itself on one channel for a special 1-channel turbo mode. Ironically, this would also be the mode most likely to produce smoke.
Some lights ship with a floor level higher than the minimum, and the user can raise the floor if desired, so there is also sort of a “basement” where a moon mode can be found.
So it seems this new function is implemented in the new D4V2 and KR4 - right?
From the description: “Anduril 2 firmware, user choose the tint ramping or instant channel switching, Advanced mode Off -> 9H, first menu item: 0C: tint-ramping (smooth) 1C: instant channel switching 4 LEDs can be on at the same time with full power.”
Yes, same die size as E21A but 4 of them on a 3.65x3.65mm package, with less phosphor around the dies so less angle tint shift (more uniform beam), limited to 4A (6V).
Above, i asked about this and The Freeman responded, it's a typo. I thought the B45AM was another, different Nichia LED i had not heard about. Just a typo from Hank apparently. :))
The driver hardware is the same and the default ramp settings are the same between the A1/A2 versions. Newer A2 versions have dynamic PWM to slow down the ramp speed at lower levels but you still need to manually set the ramp floor to level 1.
