KC1 keychain light is available now

How is the problem solved with the smoking B35AM in the new batch ?! I heard from first new D1v2 without the problem in Turbo …

The problem is not solved. My D1 (received a couple days ago) with B35AM 5000K smokes on turbo.

One solution to avoid the smoke would be to configure the light to reduce output. Users found that B35AM does not smoke if output is limited to 140/150. So, I disabled turbo and limited the ceiling level to 140. One thing to note is that this configuration can be reset, so it would be crucial that users remember to configure the light every time they reset or reflash the light.

If you let it smoke with the reflector on, it seems that the reflector gets stained. So, I would highly recommend that you avoid the smoke.

Hank said he would limit the current in the future batches, but it has not been announced yet as far as I know.

There are 2 reports, comments over on TLF about the case

“My D1 B35AM 4500K arrived today, Hank texted me yesterday that all the lamps are going through final inspection and that I can use the turbo as normal.
In any case, the first 40-50 seconds of turbo did not show any smoke on the LED :)”

“I ordered my D1 B35AM 4000K on 08/01 and he already sent me the new version. Turbo works without smoking, he also confirmed this to me by email.”

It seems the new version is ready. But we have to wait for Hanks reply

SFT-40 & FC-40 options have been added for Noctigon K1 flashlight,

RGB button has been added for D1, which can show the voltage just as K1, choose at hand which RGB color you want.

1 Thank

Now how about fitting that RGB button in D4v2?

Any plans for dual channel CC drive for D4v2?

The D4v2 is already available with dual channel : https://intl-outdoor.com/tint-ramping-instant-channel-swiching-led-flashlights/new-emisar-d4v2-with-tint-ramping-and-instant-channel-switching.html

These look cool. Thanks for keeping the single color option available, too.

Whooooo! Pretty colours!

Hank, these look like discrete R, G and B LED packages as opposed to the RGB combos used for aux lights, is that the case? Could other combinations be possible?

A very good and interesting question.


Aren't these FET ?

Constant current linear, like all the dual channel models

Hi, would you please let me know what other combinations you mean?

I received mine D1 B35AM 5000K couple days ago, with full battery it pulls 3.7A measured at the tailcap. For comparison, DM11 on level 140, pulls 4.05A.

So I guess we might assume that problem has been solved by Hank.

On a side note, the beam of B35AM 5000K looks almost perfect, very close to BBL, a bit below on medium level. It’s puzzling that B35AM 4000K in DM11 for higher current produces a bit less lux. For almost the same current SC64w HI produces even less lux and it has lower CRI. win-win :slight_smile:

Dear Hank,

you postet since these Post of me and DrDevil some new things, but not answered the question of the solution for B35AM. I think, it can not be difficult, to explain this thing, because many of your buyers have to handle this issue of your smoking B35AM in the first D1v2 …

Thanks a lot !

I think he means something like this, but in the switch. e.g. a pair of pink, a pair of warm white and a pair of ice blue

Oh, well that's better, but how about a dual channel boost driver?
I would probably just mix the leds, on boost driver, then buying linear dual channel.

@LiteintheNite My D1 mini B35AM 4000K (first batch) pulls around 2.78A on the default max ramp (that's twice less, as on the TURBO), just letting you guys know.

Not enought space on the board for a dual channel boost driver.

Oh yes. My choice would probably be cyan/ice, magenta and amber…

Hi,

The RGB switch sounds super cool but I just have a few questions.

1.) Is it a fixed selection of colours that is constantly lit up with the option of high brightness, low brightness, blinking mode and off? or does it cycle through the colours like the auxiliary lights do on a D4V2, so you can make the switch blue for example and when you get bored of it you can change it to red?

2.) If you have to choose 6 colours for a fixed selection what colour options is there to choose from?

Many thanks.
