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:
- Constant current with Temp Auto Regulation
2-3. SST40 6000-6500K - 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. 
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:

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”.
Yeah, will consider 5000K. Thanks again Unheard.
What’s mode order on outdoor? From lowest to highest is the best in my opinion. Also when moonlight was turned on with shortcut (double tail click), the next mode (after side click) should be low.
IMO output levels should be more like 0,5 - 8 - 100 - 500 - 1600.
1. Low-Mid-High-Turbo
2. If Moonlight activated, the Moonlight-Low-Mid-High-Turbo-Low-Mid-High-Turbo
Will consider output levels should be more like 0,5 – 8 – 100 – 500 – 1600, want to hear more voice. Thanks for that.

THAT is really good. 
Thank you for explaining it, I honestly think you should write that on the box and in the instructions to give it some exposure - most names are just made up - this one however has a relevant meaning, and that is rare so far as I know. Very good choice of name.
