Thanks Rayoui. Duv is looking significantly better on e21a. Are these using the same frosted optic?
Just my opinion, but in low light and without a daylight ambient reference, about –0.0015 seems actually “neutral.” Duv = 0 light almost always appears greenish still in my experience. +0.0012 is slicing or mixing territory.
Thank you Hank for the update!
The D4v2 with 219b has the narrow spot optic (10622) and the KR4 with E21A has the frosted optic (10623).
These 219b don’t appear too offensively green when I use the light on its own without any other source for comparison. To my eyes, 3500K is a color temp that seems to make slightly greenish tints appear more acceptable for some reason (as opposed to 4000K which seems to accentuate greenish tints). I noticed the E21A also appears to saturate colors a bit more than the 219b.
If you wouldn’t mind, I’d be curious how the 219b responded to the frosted optic. My bet is duv drops by maybe 0.0005. My hypothesis is the back scattered light acts like a very mild recycling collar.
Tint ramping version Noctigon K9.3 is available.
The FET turbo mode is still valid for the non E21A version.
Where are these bins sourced?
Just a quick note for anyone buying one: It’s kind of an early build, and likely to be updated in the future, so I’d recommend making sure you have a firmware flashing kit if you get this new K9.3.
Is this just a software change? Would the standard K9.3 have the same functionality if flashed with the tint-ramping version of Anduril 2?
It’s only software change, the standard K9.3 have the same functionality if flashed with the tint-ramping version of Anduril 2
That sounds like a really great improvement that adds a lot of flexibility to the use of the light.
Noctigon K9.3 with tint-ramping sounds interesting … but too big for me.
If only they made a D4V2 with tint-ramping.
A D4V2 with tint ramping and option for E21A R9080 5000K/2000K would make me buy my fourth D4 :sunglasses:
Afaict this would require a driver redesign since there would suddenly have to be separate channels for the led colors. It couldn’t be by just changing the leds and software, like on the K9.3. It’s intriguing though.
Agree,with firefly mode
It already has a firefly mode. Set the aux LEDs on low mode.
Not much redesign would be needed.
Anduril 2 already supports tint ramping. You might need another contact pad on the driver for the extra wire to the star, but that should be the extent of changes to the driver.
A new quad star would need to be made with 2 of the main LEDs on each channel. But making a new star shouldn’t be difficult. Such stars already exist on the Sofirn IF25 and Lumintop FW4X.
It should not be necessary to make any changes to the aux board, though it might be cramped connecting the extra wire around it. However, if that became a problem I’d rather have tint ramping than the aux led board anyways. Just ditch the aux board. The light could still have aux LEDs in the switch to make it easy to find at night.
Of course it needs hardware changes… it would need two regulated power channels, currently it only has one. K9.3 already had two + two led channels, hence the firmware change only.
That’s not the extent of changes needed for the driver. It needs an entire second power circuit, isolated from the first one… and it’s already a tight fit with just one.
Ok. Good to know.
Still… if Lumintop can fit it into an FW4X with similar sized driver, and if Mecarmy can fit it into a PS14 with a narrower diameter driver, it should be possible to fit this into a D4V2.
Plenty of space on the 22mm driver, especially since the DD FET channel becomes unnecessary, the wires would be more problematic but still doable by replacing the relatively thick aux silicone wires with thin Teflon wires, the main negatives wires could lose a gauge and use Teflon as well. I mean even in the current D4v2 it’s a bit of a mess, personnaly when modding one I replace the aux wires with Teflon, much more room to work with.
