Lol, unfortunately all I can gaurantee is that I’ll be less late to the party than normal 
Hopefully it’ll be quick enough to help some people out though
i wouldnt worry too much about it, seems like everyone is just ordering the lights anyway, they won't need the video until they get them in and can't figure out how to use them lol. So by those estimates you have like two weeks
If they can use an Anduril light without tint adjustment features, the differences are pretty simple:
- 3H to change the tint. (click, click, hold… or in other words: press+release, press+release, press+hold)
This can be done pretty much any time the light is on. If 3H isn’t already used for something else in the current mode, it “falls through” and does tint ramping.
If it’s a tint-toggle model, it changes immediately from one set of LEDs to the other.
If it’s a tint-ramp model, it changes gradually from one set of LEDs to the other, while keeping overall brightness steady. Release and 3H again to go the other direction. And if the user goes past the end of the ramp and keeps holding, there’s a special setting at each end for “auto-tint” mode where it changes color on its own depending on brightness.
Some models (like some versions of K9.3) also have a direct-drive channel for extra-bright modes like turbo, but it’s only on one set of LEDs. The way this gets worked in is different depending on the light. For tint-toggle lights, one set of LEDs simply goes brighter than the other. For tint-ramp lights, it functions as a short extra ramp segment above the ceiling, which ramps from the current tint to full power on the direct-drive channel. So it can jump to DD turbo regardless of what the current tint is.
If the user sets a manually-memorized level, that also includes tint. So it’ll reset to that tint and brightness when manual mem activates.
If the user doesn’t know how to use an Anduril light though, they’ll have a lot more to learn. The tint parts are relatively simple compared to the rest of the UI. The basics are pretty simple though… Click for on/off, hold to change brightness, or 3H to change tint.
As a side note, if you order an adjustable-tint light, I’d recommend getting the flashing kit too. I don’t actually have one of these new D4S / KR4 lights to use for testing and development yet, so the current firmware is largely based on guesses and feedback… and will likely be improved after I get the actual hardware.
Not sure when that will be, but hopefully soon.
This is what I was interested in. I have 1st gen FW3A with a JCCustoms mod where you were holding a switch from Moon, tint would go from aux leds moon to max and past that point it will switch to Moon on main leads and further to max.
This is the only "tint ramping" model I have atm.
Seeing videos where tint changes I thought it will hold desired tint once the button is released and to be used from moon to max but as I'm seeing from D/O it's only a pleasant and slow transit from one tint to another.
That would actually be pretty cool. I’ve never seen that. To ramp from AUX to Main. Nice!
I think contactr made a few builds and videos with that feature. If he's here maybe he could post one of these movies to show what we oldtimers actually think tint ramping is...
Oh wow. I’m loving Anduril and a bit of Anduril 2 but the tint ramping is not something I considered yet. So the smallest Tint ramping light is the Kr4? D4v2 wouldn’t Work?
Can we get say 2700K and I dunno 4500K Nichia 219B? When you say tint ramp we are talking colour temp right?
I think it’s only one or the other…
It’s not specifically tint ramping, but actually channel ramping. Your emitter choices determine whether it’s tint ramping, color ramping, hotspot-width-ramping (digital zooming, sort of), or whatever.
If you have emitters with two different color temperatures (like 219B’s in 2700K and 4500K), then the color temperature will ramp. If you have two emitters with different intensities (like W1’s and XPL-HD’s), then the hotspot width will ramp (basically). If you have one set of green emitters and one set of red, then the color of the beam will ramp between green and red with every color in-between.
Thanks. Interesting possible options. I’d probably go all Nichia 219B but I wonder if they would work well with sst20. Hot spot ramping? Could be intriguing but maybe just colour temp would make more sense.
TK, absolutely, I was just being a little facetious :)) it's really not that bad, and I honestly think the terminology is confusing more people than the UI would. I have a k9.3 and, like you said, If you already know Anduril, it's pretty intuitive and you catch on quick. Tint ramping should be the same idea. I'm getting one in a KR4, I think that is pretty amazing!
The collaboration and communication between everyone is awesome. From Hank, TK, Luxwad, Griz, Artie, ID and others. Love it.
With these tint-ramping models, are other features cut from Anduril to make room for those options?
3H from on ramps/switches the channel on these, where as single-channel Anduril 2 lights use 3H from on for momentary turbo. Other than that I don’t think there’s any change.
So a D4v2 can’t have tint ramping right?
I think it was stated upthread the driver will not fit in the D4v2.
Thefreeman has shared a two-channel driver design of his own that should fit in a D4v2, but I don’t know if he has tested it yet (he mentioned some firmware limitations that were outside his skillset), and of course, that’s his own design, not what Hank is using.
Hank, will you have the Nichia B35A and suitable MCPCBs for sale separately?
Thank you so much for the work you do for us 
I wanted to ask about the direct-drive channel for Turbo mode in the K9.3 flashlight. Let’s take the Noctigon K9.3 flashlight with the Anduril version of the Tint Ramp (channel ramping) with LEDs:
9x XP-L HI 5000K on Channel 1 (9A CC + Direct Drive) and
3x Nichia 219B 2700K on Channel 2 (5A Constant Current).
Let’s assume a situation where we stand in the middle of a tint-ramp, all the LEDs from the first and second channels will be lit. Now we will increase the brightness to the ceiling level of the ramp. All the LEDs will still be lit. But what happens if at this point I press 2 times (2C) i.e. turn on Turbo mode? Then the LEDs of the first channel (XPL HI) will light up with maximum power supplied by the FET DD. And what happens to the second channel (Nichia 219)? Nichia 219 will go out completely?
My second question is about the D4Sv2 flashlight with the Anduril version of the Tint Ramp and with the same LEDs as in the K9.3.
2x XP-L HI 5000K 9A CC
2x Nichia 219B 2700K 5A CC
In this design the FET is turned off. We can mix the color temperature freely.
We have the flashlight on and the tint-ramp set to center, all LEDs are lit with similar brightness. Now after activating the Turbo mode by pressing 2 times (2C) the brightness will change to the top of the ramp, and what will happen to the tint-ramp? Will the diodes from two channels still be lit? How will the power supply be implemented then? Will the 9A current be divided among the 4 diodes in maximum brightness mode?
Hank,
will it be possible in the future (or possible now) to get the K9.3 with a 9amp CC driver for Channel 2? In the event of using w1/w2, or even sst20, 9amp would be a real upgrade for the (3) channel #2 LED's. Thank you!
