The specs you mentioned seem good!
I would only like to know about the User interface and output levels.

What does the tailswitch?
What does the side switch?
How do they work together?
What is the lowest level?

Remember to take my suggestion to perfect the beam pattern. I sent this to you in my email following my review.

The beam is a bit ringy. That is the only thing to perfect. It is still one of my favorite all-time flashlights. Above that, getting it up to about 700 meters throw might be cool.

I really couldn’t find anything wrong with it. The output was a bit low so maybe boost that a bit since thermally it was good. The only other option is an upgrade to the sft70 with a boost driver. That will help output a lot and maybe even the throw.

I do like what other companies do with the side switch like Acebeam. Let the side switch and tail switch control on/off and keep the tail for instant Turbo.

I don’t have this light, but I’m just trying to comment from watching rusty video.
Make sure the turbo mode is in the mode sequence without having to double press the side switch.
Turbo mode can be memorized.
Holding down side switch from on or off will activate strobe. Single click will activate last used mode. Would also be nice if strobe can me memorized as well. But not as important. Would be very cool to have strobe in momentary.
Fix the beam
Fix the side switch for less to no rattle. Maybe a different side switch would be nice, a more tactile raised stainless switch?

Any plans on weapon mounts or remote pressure switches that replace the tailcap? Remove the strobe.

I need a better light for my AR15.

I’m a dealer for Cyansky just for their HS6R headlamp. I was interested in the K3 as a gun mounted option since it does have a remote switch, but….I need a spring on the positive end, not just the negative, this prevents any flicker from the recoil and stops any damage to the driver.

The Remote Switch needs to not just be able to mount onto a rail, this limits options. I have many hunters who like to use double sided tape to attach it to the side.

I don’t like the UI. It needs an instant turbo accessible from the tail switch. Just because it has dual switches doesn’t automatically qualify it as a tactical flashlight, you must have a tactical UI to go with it. Perhaps design it to have two UI modes, one for outdoor use and the other for hunting/tactical with it always activating in turbo.

I’d like to see that turbo being 2000 lumens if using the SFT40.

The only other thing that makes it less ideal for hunting is the SFT40’s limitation in 6500K. Cooler tints are completely ineffective in bad weather, in fog it’s like hitting a wall and becomes entirely useless. Maybe also look at other LED options, unless of course you can source the 5000K SFT40.

They already sell a remote switch for the K3

I always like the 3 “instamodes” model:

Press’n‘hold for moonlight.
Click for last-memorised mode.
2click for turbo.

Turbo by definition should be an unsustainable mode of “emergency brightness”, whereas “high[est]” would be the brightest sustainable mode.

Nobody seems to do that, though, which is why we’re all hip-deep in lights that have “turbo” for 10-30sec.

USB C charging. I’m in the annoying position of my chargers not supporting 21700. I’m probably not alone. Besides, it’s convenient not having to carry a charger around, just a cable all my devices can use.

It has USB C charging on the battery. Having it on the flashlight only works if it’s hidden in the threads or magnetic, having a rubber cover is a possible water ingress point once it tears off in time.

Hi, guy.

The UI of K3 is very simple.

The tail switch controls the power on/off.

Side switches control mode conversion.

The lowest level is 30 lumens.

Below are the parameters.

Next, we will upgrade this product. Big Smile

Wow~ Thank you for your recognition of K3. Beer

If this product is upgraded, the brightness will be improved. As for the choice of LED, we haven’t decided yet. It is possible to continue using the SFT40. It is also possible to use other LEDs.

In terms of UI design, we don’t think it’s a good idea to use tail switches for instant turbo. But we will listen to users. Thank you for your opinion. Beer

If it’s going to be marketed as a tactical flashlight, the current UI is terrible. Imagine forgetting you turned it off on low, holding a pistol and switching this on in the other hand, crap, what now? No possible way to switch it into turbo from the tail switch. If it’s just an outdoor model, it’s fine as is I guess.

No, it’s not. It means you are irresponsible for going into a situation where you have not tested your light before using—if, say, going to do a room clearing or takedown or something in law enforcement. But the ability to use the light reliably with two buttons and not an accidentally activating side-switch is needed. I want the ability to use the light in constant low as well as constant high when needed.

This is where a dual UI comes in handy.

Sirstinky reviews for 1Lumen so I’m fairly sure he knows what makes a good tactical model. Make a poll and I guarantee the majority of the vote is going to be for an instant turbo option

Not quite “tactical” other than snooping on critters making noise in the backyard, but that’s why I keep my GTmicro in momentary mode.

Funny how an “antiquated” UI like narsim is useful that way…

I do as well. Just different schools of thought. I am just too familiar with terrible lights accidentally activating by those god-awful Acebeam sideswitches. Nothing like giving your position away with the damn side swtich coming on in your pocket.

Anyone who wants the Acebeam style doesn’t really know tactical, in my opinion.

There’s a difference between a true tactical use UI and an “outdoor UI”. Tactical UIs always have a provision for instant Turbo or High mode and Strobe modes. There are other nuances but that’s the important bit. Everyone does it differently. The K3 doesmt have a true tactical UI. It’s like a hybrid version.

I really like the Fenix TK16 and TK20R V2 and Klarus XT11GT setup with dual rear switches. Doesn’t matter what mode you’re in, you can always call up Turbo or strobe. I think Olights setup is my favorite though like on the Warrior 3S…dual position tail with independent/redundant side switch. The Odin WML has it spot on…single click for High, and Low, no memory. The Acebeam L18, L19 features this also (an upgrade from the L17).

Bottom line if you don’t want a true tactical UI, get a K3 (or Speras E3).

Hi, This is a simple model, and you know it pretty well from the video. Thumbs Up
The turbo mode is in the mode sequence.
Turbo mode can be memorized.
Holding down side switch from on or off will activate the strobe.
Strobe can not be memorized, but all of our lights can be accessed directly to the Strobe by long pressing the side switch for 1 second.
Fix the beam. What kind of beam do you think it could be?
Fix the side switch for less to no rattle. We will consider improvements.
In the new version, we will make a more tactile stainless steel side switch with a battery indicator.
Thanks for your suggestions. Big Smile Beer

I don’t want to get offensive, but just use a one-mode light if you are that insecure about not having turbo come on in some dreamt-up moment of crisis. That solves the problem for all time (The CPF people used this logic to justify the Surefire Centurion as light of the year for SWAT people many years ago).

A tactical flashlight is a light with mode memory and momentary-on with forward clicky and the ability to flash in signals. “Outdoor mode” is just another new and made-up term that really has no clear meaning. We all know what tactical means.

I want my tactical light to light up in MY selected mode every single time AND not accidentally come on in my pocket like Acebeam lights do.

Cyansky can create another (K3b?) type light for your needs. I don’t want them to change the original.

Lookit the 2-switches-in-the-tail setup like the TM03 and probably other Tiny Monstors.

Button is momentary-on, or full-click. Lights up in last-used mode.

“Crescent” switch is for mode-changes when on. When off, it’s momentary-on for turbo, or 2click for strobe.

It’s “reversible” to swap strobe ⇌ turbo with a way to do it (unscrew, press/hold button, rescrew while holding for 10sec, or something like that), so if you want strobe to come on via the crescent-switch and 2click for turbo, have at it.

Best friggin’ way to do it, if you want multiple modes instantly accessible and extremely unlikely to come on “wrong”.

That often means standard 21700’s aren’t compatible. Is that the case here? See this so often and it’s an instant pass from me.

i dont like this super-simple ui. but this is matter of choice. 

for me Sofirn C8G UI is example of how it should be done for dual-button UI.

no spring at head is really bad for gun mount. 

and button as is invisible for finger. i remember it was really hard to blind find it.

 

i believe K3 may be way better with few, not rocket-science, changes

Thank you for your feedback. We will improve this. The head of the K3 V2.0 flashlight will be switched to a spring, which is compatible with both flat and convex head batteries. And can be more impact resistant. Big Smile
