KC1 keychain light is available now

If TIR will be installed then aux lights could be the option. Just look at Loneocean’s build

Yes, I have both the AM and AR, and was trying to decide which one to use, thanks for helping me to make the decision.

Yes, you nailed it, 40mm head exactly.

With aux LED for sure.

Please just make the best light possible and don’t worry about the cost. None of these lights are really unaffordable and we all have lots of lights. If the new light ends up using more of our flashlight budget, it just means we buy fewer total lights. I’d rather have two or three great lights than spend the same amount on five crappy or compromised ones.

Maybe enlist the first Hank BLF collab. =]

AM = R9080

After checking both AR and AM are available in 9080 : Product Data LED | NICHIA CORPORATION

The choice between the two is rather about efficiency (AM/6V preferable).

An additional LED that could be offered with it would be the XHP50.3 HI, if it proves to be good. A 6V driver here is also preferable for the same reason and that the MCPCB is just a simple XM one.

What he said ^^^^^^^^^

Looking forward to this light! Thanks Hank!

Bonus, if it takes off the shelf TIR optic from Ledil or Gaggione, people can customize their beams if they chose to make it floodier than stock.

Sure, we will use the most high quality MCPCB and parts with it.


I hope it will retain KR1 look and not Sofirn IF22A…

Hank confirmed 40mm so it won’t be as many dreamed pocket friendly.

And that’s why we will keep paying a bit more for your awesome quality lights, keep it up mate

as much as I would love to see the AR being used for the 12v compatibility of the Xhp35 HI (3000k hi cri and 4000k hi cri), and also possible mods with the gt fc40 leds.... - I do like the sound of higher efficiency in the 6v variant and the compatibility of the xhp50.3 HI

my first vote would definitely be for 12v b35AR, because xhp5.3 can be made this way too. but If I am in the minority here please let me know..

Maybe do both voltages, so you can hit multiple emitters with 12v and at the same time keep the efficiency of the 6v b35AM.

My Getician 4500k in the Acebeam E70 is beautiful, but paying for premium metals (ie brass copper and titanium) makes it ridiculously expensive $150-180+

Well they’re gonna have a 12V version anyway since XHP35 is apparently already planned. The driver itself only needs a few components changes between 6 and 12V (Rsense, Vsense divider and maybe compensation passives), but it’s true that having only one version is advantageous because it means only one variant to manufacture and handle. Although it seems that Hank prefers to actually have multiple driver variants rather than modify the current in software in the case of the 5A,7.5A, 9A linear drivers where one resistor is changed to set the current.
Difference in efficiency can also be minimal, I was thinking of the TPS61088 where the efficiency at 12V is significantly lower, but with other converters like TPS61288 or MP3431 there is not much difference.

Freeman, thank you so much for your input here. I always really appreciate it because it's so informative. I'm glad to hear that the 12 V xhp35 hi is already on the table. I'm also glad to hear that if this other MCU (?) Want to be used at the efficiency would be somewhere between 6 V and 12V. That is great news, and I know it's a lot more manufacturing and maybe more cost for Hank but it is nice to have multiple drivers for us to, because Hank will sell us parts and drivers and we can mod his lights and other things with his fantastic creations.

Most multi-cell lights with rechargeable cells use the cells in parallel, I think, which decreases the hazard of reverse charging a cell and maybe igniting it. So 12 volts would need a boost converter. A fancier approach could involve independent voltage monitoring for each cell, but that would be hard in the traditional tube-shaped flashlight format (maybe better for soda can) and would would require more software that would have to be tested thoroughly.

Hank, thank you for responding to feedback here for influencing upcoming designs.

There is one general area of improvement that everyone will want, even if they don’t know it yet, and that is a different AR coating. Currently, the coatings reflect a disproportionate amount of red and blue, and very little green. This causes the Duv to increase by a small but noticeable amount and makes it harder to achieve ‘green-free’ light output so many enthusiasts desire.

If the coating is changed to a variety that reflects more green than other wavelengths, this behavior can be flipped. Duv will be lowered slightly and LEDs like SST20 and SFT40 that are hard to find without a green cast can be made more neutral.

The difference between two different lenses that behave in opposite ways can be as significant as 0.0050 Duv.

I completely agree. I prefer to have no AR coating rather than most coatings that I’ve seen.
