How do you think about YAKORSEI GD12 TNO flashlight ?

Hello BLFers,

We are developing a TNO flashlight( tactical and outdoor), how come? It is a flashlight with tactical OS (Operation System) and outdoor OS, controlled via a side switch and a rear switch, check out the look of it with the pictures below

Design:

User Interface:

Tactical OS
ON/OFF: Click on the rear switch to turn on or turn off the flashlight.
Instant Turbo: From off, single tap on the rear switch to activate Instant Turbo, and further click to turn constant on Turbo.
Instant Strobe: From off, double tap on the rear switch to activate instant Strobe, and further click to get into constant Strobe.
Output levels: From on, click on the side switch to swap between Turbo <=> Low, designed to be always turned on Turbo. Double click to activate Strobe, Triple click to activate SOS, single click to return to constant on.
Sum up( Always to turned on Turbo, Instant Turbo, Instant Strobe, switch between Turbo-Low, Turbo-Strobe).

Outdoor OS
ON/OFF: Click on the rear switch to turn on or turn off the flashlight.
Memorized output startup: From off, single tap on the rear switch to activate the output level on which it was turned off last time, and further click to turn constant on that output.
Moonlight startup: From off, double tap on the rear switch to activate instant Moonlight, and further click to get into constant Moonlight.
Output levels: From on, click on the side switch to cycle through Turbo-Low-Med-High. Double click to activate Strobe, Triple click to activate SOS, single click to go back to constant on.
Sum up( Memorized output startup, Moonlight startup, Hidden SOS).

OS switching
From ON, press and hold the side switch for 3s to switch between Tactical and Outdoor OS, flashes 3 time to turn on low for outdoor OS, while flashes 1 time to turn on Turbo for tactical OS.

Instant tactical OS: From OFF, press and hold the side switch and click the rear switch to turn on Turbo on Tactical mode.——You don’t need to go through a complicated operation.

Parameter

You are welcome to comment below to talk about how you think about this flashlight.

We would like to hear your opinion about it. Any comment will be appreciated.

What if i want to be tactical whilst outdoors? is there a mode for that? :smiley:

You can switch either via 1. press and hold the side switch when the flashlight is ON. or 2. Hold the side switch and click on the rear switch from OFF.

Thanks for your comment. It has operation systems switching, you can switch between Tactical OS and Outdoor OS according to your demand.

IMHO, the UI looks okay except for one thing in the Outdoor OS:

Turbo mode is in the standard mode order and strobe will be accessed via doubleclick. I would rather remove Turbo mode from the standard cycle and access it via doubleclick while strobe could be accessed via tripleclick and SOS via quadrupleclick. Personally, I would remove strobe mode completely and only leave SOS mode available by tripleclick.

A second mode group for ramping (stepless brightness control) would be a nice add-on. Most people here seem to like CLICK for ON/OFF and HOLD for mode cycling. A lower moonlight than 11lm would also be great.

What driver is being used in this flashlight? (e.g. constant current or direct drive)

What LED is being used? 1.600lm max looks like XP-L HI to me.

What CCT / tint did you choose? Anything above 5.700K is often considered as (too) coldwhite.

Do you use an OP or SMO reflector or a TIR lens?

Hi Lux-Perpetua, thanks for your comment,

We have considered double click for Turbo at the beginning, but then Strobe will go to triple click, and it will take longer time to carry out Strobe, and if you need Strobe, normally should be using it during a emergency, therefore you will expect it to come out more quickly.

We will consider ramping in our other products, you mentioned moonlight, but do you mean 1lm when you said 11lm because we already set moonlight 1lm?

Answers to your questions:

  1. Constant current with Temp Auto Regulation
    2-3. SST40 6000-6500K
  2. SMO reflector

Looks interesting. Its a common size format and good to see you are lifting the lumen level to 1600 as there are many models on the market of a similar design with 1000.
You may want to consider offering warmer tints too on the led.

(1) when on, press & hold the sideswitch should turn the light off (standby), allowing using the light without the tailswitch.

(2) delete mode memory register after moon-mode was activated, i.e. the next mode should be low.

(3) low is not low enough, think about 10 to 20 lumen.

(4) 11 lumen is not moon. Should by lower than 1 lumen.

Consider 5000K. The SST-40 is beautiful in this tint, still white.

Yeah, 6500K is so last year…

I think Folomov had “tactical” and “outdoor” modes similarly. Nitefox, too.

Anything with blinkies not very well hidden is disliked by many. By the time someone thinks, “Oh, there’s someone trying to kill me, let me doubleclick to start strobe”, he dead. Strobe just annoys and angers killers, makes them want to kill you more.

Hi Rolz, thanks for the comment. What tints do you think will be proper?

Hi Unheard, thanks for your comment.
(1)Total without using tailswitch, we may need to apply dual battery tubes. If you need to click the tailswitch first, then it is not a problem, then it is not as good as a flashlight with only side switch, in this case we will have product like this in near future.
(2)That works exactly like that, once you activate Moonlight, click on side switch you will go to Low.
(3)10-20 lumens for what kind of scenario?
(4)I also assume Lux-P meant 1 lumen.

5000K looks a little yellowish, not sure how other people think about 5000K or if any other idea.

Picture 5000K VS 6000K

Low for orientation in the dark, preserving battery capacity, and moon for preserving night vision. 100 lumen is already very bright, and 11 lumen will destroy night vision. Currently you have low, mid1, mid2, … but not moon.

Please see with your own eyes. 5000K is neutral white and not considered yellowish.

Thanks for your comment Lightbringer, yeah, can’t agree with you more, I have used flashlight with SOS and Strobe cycle with Low, Mid, High, I just put it somewhere.

Double click is not too bad, not too easy to activate. Hope to gather more idea, so that we can satisfy most people’s demand.

I’d suggest 5000k too as an option, I know some would prefer lower too but 5000k may be a good compromise.

I just can’t see past ‘YakHorse’ even though it doesn’t say that. :person_facepalming:

Thanks Unheard,
Agree with Low setting for the point of preserving battery capacity. Regards the Moon setting, now we have Moonlight output with 1 lumen. Regards the tints, are you okay with tint in the picture?

Thanks Rolz, I hear you. :sunglasses:

G0OSE, the meaning of YAKORSEI is nocturnal, Japanese pronunciation.

Nocturnal夜行性Yakō-sei

I know the SST-40@5000K, used it in a Convoy C8 and Sofirns SP33V3. Yes, I’d prefer it.

Your picture shows a white balance that’s a little off due to the camera seeing cold white as white. If it had used the 5000K light, the CW would look plain blue.

Edit: Please have a look at Armytek lights - IIRC, they use something like 4000K as “warm light” and 5000K as “white light”.
