Anduril has a setting to increase output when tint mixing, by default at middle tint both channel will be at 70% instead of 50%, if I understand correctly:

#ifdef USE_TINT_RAMPING
        #ifndef TINT_RAMPING_CORRECTION
        #define TINT_RAMPING_CORRECTION 26  // 140% brightness at middle tint
        #endif

But instead of that I think that there should be an option for 100% on both channel for turbo, meaning turbo will be only middle tint but IMO that’s not a problem. This would need to be implemented by Toykeeper.

This only works with tint ramping with 2 power channels, not one power channel shared between the two LED channels (Sofirn IF25), but I think Anduril only works with the former anyway.

So… did dark ever happened to you?

Hey Hank,

Any chance of making a variable tint version of the Emisar D4?

For variable tint, you would need 2 warm emitters and 2 cool white emitters. (probably SST-20s would work best). They would need to be on separate channels so you would likely need a custom quad star.

But apart from the star, everything else can be done with stock components. Anduril 2 comes with built-in support for variable tint lights so you can use existing firmware.

D4V2 with 4 emitters may too dim for the variable tint, I assume 10+ emitters will make much more sense.

I also think a version of the D4 that has variable tint would be an interesting light. 4 emitters would be a tradeoff for output versus compatibility with optics, but I think it would be a good tradeoff for an uncommon feature like variable tint.

I think the driver could be similar to the KR4. Instead of the two channels being 5A constant current + FET, they could be 5A + 5A constant current. This should still produce 1200 lumens or more.

I agree

It’s seems many who appreciate the finer details of the modern flashlight have Hank lights, custom versions etc. I have a fair led light collection yet not a single Emisar light. In not sure where to start maybe the D4v2 it seems popular.

The D4V1 was my first, (this was back in the day!). It has been on from there. Now since we are in modern times, (joking, it wasn’t that long ago!), I would highly recommend the newer version of the same and say to get the D4V2 you speak of. Emisar really are my favorite lights. That is coming from someone with over 150 lights by various brands.

I defintely do not have anywhere near as many lights or Hank lights as others on here, but I have about 15 of Hanks lights, and I am a KR4 / KR1 fan. I carry either one everyday, but most the kr4. I have it in a couple emitters all of which are good. I would say if you like tail switches do kr4, if you like side switch go with d4v2. Don't bother with the 18350 tubes as these lights are compact enough. But either way you would not be disappointed!

oh, and if you are bot in the market for an edc but want a thrower, get the entry level prices CULPM1 (white) K1. For $89 or whatever it is, you will not find a more fun thrower. EDIT: it has good throw and good usable spill for an osram LED. When I light up targets a couple hundred yards out The hotspot is a really nice larger size.

D4V2 Ti is probably the single best way to enter Hankland. Emitter choice needs to match how you plan to use it.

I like the Ti feel and durability much better than the aluminum, so I never recommend the aluminum as a result.

I’m itching to get another one of these but have a question. Does the E21A D4V2 use the same driver as the E21A KR4? Constant current + direct drive?

[SKV89]

I don’t see the XPL-HI T6 8D option on the website. Can you tell me where you ordered it?

@pol77

I received my D4V2 Ti with XPL-HI T6 8D emitters and made some measurements to compare the max output level to other Hank lights I own. I will post them here, as a point of refference for anyone that is interested. Included, are 2 D4V2 Ti lights with Nichia 219b emitters, which I modded myself. All lights use the standard driver except the E21A lights that use the 5A CC driver.

According to my measurements, Hank’s lumen values are quite optimistic. I have calibrated my setup with 3 professionaly measured lights and all Olights that I measure are spot on (Olight is known for giving accurate lumen values). That said, the lights are still very bright, just not as bright as advertised.

Here are my measurements. All values are at startup. The batteries used were a 20A 18650 and a 10A 18350.

	D4V2 Ti XPL-HI V3 3A	D4V2 Ti XPL-HI T6 8D	D4V2 Ti 219b sw45k	D4V2 Ti 219b sw30	D4V2 Ti E21A 3500K	KR4 Ti E21A 2700K	KR4 Ti E21A 2200K
18650	3693	2365	1634	1455	1041	949	775
18350	2991	1961	1478	1292	1041	949	775

The (very) first impression on the T6 8D emitters is that they are very warm and nice. They are actually warmer than the E21A 2700K but not as warm as the E21A 2200K, so I would guess they should be somewhere in the 2500K area, but I do not have the equipment to measure that. They seem to have a pleasant tint, below BBL, but next to the 219b sw30 they look greener by comparisson, albeit warmer.

Colours rendered under the T6 8D pop quite nicely and the reds are much better than the R9 value of the emitters suggests.

All in all, a very nice emitter. I still prefer the 219b emitters, but a 62.5% increase in brightness while being also about 500K warmer and maintaining a >90CRI is a definite win for me.

Here is the backup. My Luckysun D80 from a few years back came with a purple coated lens, my Wildtrail D80 V2 from last year came with a green coated lens. I tested the tint in the hotspot of the same flashlight (D80 V2 modded with sliced “dogfart” led) on the same setting (350mA) without, with purple and with green lens. (I forgot to write down the CCT with the purple lens, sorry about that).

I would have never guessed the purple AR lens would make the tint more green than the green AR lens. Not very intuitive.

Hank invited us to ask him for that emitter ; go back in his interventions to see it . He said it was limited quantities, so maybe still some left .

It makes sense if you think about it this way: the color it looks in those pictures is the color that gets reflected. So the green is not passing through the green lens, therefore green is getting removed from the light passing through.

You need to order the light with XP-L HI V2 5D emitters and email Hank to replace the emitters with T6 8D. That is what Hank said. But I would email him beforehand, to make sure he still has some T6 8D emitters left.

[id30209]

I did order KR1 and email Hank but unfortunately, T6 8D is sold out...

Now he has U4 8D. 80CRI
