KC1 keychain light is available now

hey Hank, can you add on your website somewhere, in the description of the flashlight, or directly in the drop down color menu.
What type of finish is each color of the flashlight. Like HA III if it's Hard Coat Anodize type III, and HA if it's just hard-coat anodizing, and so on.

Hank confirmed he can so 12A by request on D4SV2 over on Reddit, and I imagine he can do that for other lights too.

Anyone know what the coating is on the d1.12, specifically the white ones?

Thinking of getting the DM 1.12 with SFT-40 in center and SST-20 4000K for perimeter… It’s another $20 for having the 219BT-V1, R9080 4500K on the perimeter. Is that worth doing, or would it be a negligible difference?
(I just wish the dedomed 519A wasn’t so steep… that’s another $50 USD).

Accidental edit. Ignore.

Not too long ago, I received my first two D4SV2’s, and one of them has a slight gap around the buttons retaining ring.
Im wondering if this is a concern regarding water resistance?
Im a bit worried about using this light in the rain.

I also wonder if this has anything to do with why when the aux are set to low, the four lights under the button have one brighter than the other three.
My other one has a perfectly seated retaining ring, and all four button lights are exactly the same brightness.
Not a huge deal. They both work perfectly otherwise. But its kind of annoying.

I can’t comment on the retaining ring clearances, but those look like warm white button LEDs and it’s been widely established that the brightness not being even is normal specifically for that color.

Can the back-lit button on the D1v2 be turned off? I don't need it on when the light is not in use and I most definitely don't want it on when the light is in use; annoying as hell. Does Hank offer the option to have a regular, non-back-lit button with the black boot?

If it runs Anduril, 7 clicks ought to get it flashing, then another round for off

I think it looks kind of cool. You lucked out that it happened to be the LED on the “bottom end” of the switch as the light tailstands. If it was on the sides… much more “askew” looking.

7 clicks from off will cycle what mode the button is in while the light is off. The modes are low, high, blinking, and off.

You cannot change its behavior while the light is on unless you flash a custom firmware that specifically disables the switch LED while on.

Hank should be able to easily install a regular non-lighted switch and even a black switch boot via email request before your order ships.

Thank you.


You got lucky that it's bottom one.
I got one on the side, that is dimmer. I Asked hank about it, and received this answer

"It's normal for this small LEDs to have different brightness, since they have different VF value."

from my understanding Its peculiar bad with the warm white.
That's why for next purchases I chosed cold white.
Testing them is probably to much labor intensive

And yes, it's worst in reality, then in the pictures...

The amber color comes out really good, very even brightness. Also very dim when on low which is great at night.

Hi Hank. Random question. How do you prevent particles from getting on the reflectors/lens when you assemble? Is your lab pressurized? Any recommendations to help prevent contamination? Thanks.

Good to know that. I think I’m going to go amber instead of warm white.

I think this is the common issue for the B35AM LED itself, the MCPCB is the best that we can produce, and there is no soldering issue whatever.
The LED will not die at high current (3.6A), but the smoke will come out on turbo mode.
We plan to reduce the current of the B35AM LED, this is the only way to prevent the smoke, only that the output will be reduced as well unfortunately.

It looks great too, especially on a cyan body imo!

Thanks for the information, we have changed the resistors on the driver, now the SST-20 deep red LEDs work perfectly fine with the boost driver.

UV 5W 365nm with ZWB2 filter is available for D1

Very cool! Will this be an option for KR1 as well? What driver is being used for the UV emitter?
