Emisar D3AA is available now

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 :slight_smile:

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!

It’s great that you made a new driver for the Emisar D4Sv2 with dual channel support :+1: This flashlight has great thermal capabilities. With a new driver it will keep the brightness high wonderfully :slight_smile:
I have a few friends willing to purchase a few units.

I am interested in the “channel ramping” version with diodes:
On the first channel: 2 XP-L HI 4000K LEDs powered by 9A CC.
On the second channel: 2 Nichia 219B 2700K diodes powered by 5A CC.
These diodes require different currents. Can you prepare such a version?

In a situation where the brightness is set to maximum and the Tint-Ramp is set in the middle (so that 4 diodes are lit) then what current will go to the diodes?
9A/4 diodes=2,25A or 5A/4=1,25A?

:question:

I am still interested in the second version of the Emisar D4Sv2 flashlight with four Osram W1 diodes. I would buy a few of such flashlights if you would make for it a single channel driver with full stabilization like KR4 flashlight has (9A Constant Current + Direct Drive). Are you able to prepare such a driver for D4Sv2?

D4Sv2 with 4 Osram W1 diodes is offered with obsolete driver (FET+ 3). I think a lot of people would like to buy a D4Sv2 flashlight with Osram W1, W2 or XPL HI diodes if it had a driver with KR4 (9A CC + DD), because KR4 driver gives very good stabilization.

I own all models of your Emisar/Noctigon flashlights :sunglasses: I hope to enlarge my collection :innocent: Thank you for making such cool flashlights :slight_smile:

I’m wondering. On a kr4 with tint ramping. How is the beam when only one channel is active?

The beam pattern is almost the same as all 4 LEDs are on.

Thanks Hank. How do I order tint ramping kr4 again. None for D4v2 right?

There is purhcase link on the site, you can order the regular KR4 on the site, and let us know the order number,
it will be fine.
