Manker/KRONOS Tactical EDC Forum Special Buy

Commercial Sellers' Spot

Introducing the Manker KRONOS light marking Manker’s 3 year anniversary (M/N TBD)…a small, AA/14500 tactical EDC light that has a very unique feature…a reversible bezel. $38.00.

Check out this torture test video posted by member Charles Lin. Warning! It’s BRUTAL! :smiley: :

This light is all but ready to go. UI and type of switch are to be determined by BLF members…through polling, which I will post on a separate thread after a bit. UI Poll now active HERE!

UI Poll will consist of 4 different options:
Option 1: 5 modes, Moon-Turbo, mode reversal, no memory.
Option 2: 5 modes, Moon-Turbo, mode reversal, memory.
Option 3: 4 modes, Moon-Turbo, mode reversal, no memory.
Option 4: 4 modes, Moon-Turbo, mode reversal, memory.

Switch option:
Option 1: Forward clicky
Option 2: Reverse clicky.

Once these options have been settled, we shall advise you how to buy this unique light.

Here are the specs:

XPL Hi CW 6500K and NW 5000K.
T01 Driver.
AR coated lens.
SMO reflector.
Copper emitter board with DTP.
7075-T6 Aluminum.
SS tactical/reversible bezel.
AA (350 lumens) or 14500 (800 lumens) - Estimated.
HAIII Surface Treatment.
White (light gray) or Black.
Anti-roll tailcap.
Lanyard.
Square threads.
Cigar grip with 2 lanyard mounting holes.
Clip.
Easily accessible rear thumb switch.
OAL: 105mm (with bezel aimed toward rear)
OAL: 116mm (with bezel aimed forward)
Head (bezel) Diameter: 35mm

As stated above…there are two items to be determined by future poll:
Switch type (forward or reverse clicky).
UI (4 options).

7075 aluminium… Yay. As in 7075-T6? :sunglasses:

I want one… where do I spend my money?

Looks cool

Yessir.

Sweeeeet! I believe Manker’s first light (Torch Club) was made from 7075-T6 as well… Pretty rare in flashlight world.

The reversible is indeed unique, but with it forward and being so aggressive, I would think a forward clicky with an option for instant turbo mode would be called for. My wife recently asked for such a self-defense light. She was mostly describing a strike bezel but, and it could be just me, I think it should be accompanied by an easy-access turbo mode. Having said that, I prefer lights to start on moon.

What are its advantage(s)?

G'Day KRONOS,

What are its dimensions?

Hi George,

7075-T6 is pretty much the most popular aluminium alloy in the aerospace/high tech business, and it’s roughly 50% stronger than most common “aerograde” alloys used in flashlights, which are 6061-T6 and 6063-T6.
Strength wise you really don’t need it, but personally I just think it is cool. As far as I know there are only a few flashlights made from 7075-T6, which are the Thrunite Catapult V2, V3 (not V5) and Tiablo lights. Although a manufacturer states it’s 7075-T6, you don’t have certainty that it actually is so though…
Most common problem with 7075-T6 (for flashlights) is that anodising is much more difficult than with 6000 series aluminium.

G'Day hIKARInoob,

Thank you Very Much for your reply.

Yes, it is as I expected and knew. But I thought I may have not considered some other aspect.

Best Regards,

George

WOW!!

I want

Any chance of a ring to replace the bezel? Would not be really pocket friendly for any one wishing to use that clip.

Aerospace grade, woohoo . Actually all aluminium is aerospace grade. Even 100% non alloy pure aluminium. It's just a phrase that makes people think there must be some sort of inferior regular aluminium.

Anyway, all of it and it's alloy's have their own particular strengths and weaknesses. The weakest of them all (pure aluminium) is also the strongest, in one particular application. Corrosion resistance.

2024 in various tempers (the T designation) is, in my experience, the most used alloy in aircraft structures because of its particular combination of strengths. It's durable, workable, somewhat corrosion resistant, has a good balance of mechanical strengths all while being fairly lightweight. It's not the go to alloy for everything though.

There are many different alloy's used in aircraft construction and 6000 series isn't all that common. Basically just stuff that needs to be weldable (there are exceptions)(usually non structural).

7075 T6.... Hmm I hate it, it's tough as $&#+. It's hard to bend, shape, drill, sand, grind, scratch or dent. (Of course I'm speaking in terms of aluminium. It's not like it's 316 stainless or something).

Sounds like a great material to use for flashlight making huh

The thing is that with 7075 T6 the metal is much HARDER than 2024 or 6061 even with the same temper designation (T6).

Thats great for flashlights because you can have super smooth bare metal threads (as long as their within tolerance) that won't easily gall and a bare metal finish that's way more resistant to scratches and gouges. I'd say 20 times more resistant than what's seen in everyday budget lights.

If your gonna use aluminium to make a flashlight, then 7075 T6 is almost as good as it gets.

Only XPL-HI emitter available for BLF GB?? It seems like Nichia 319 hcri LED is also available as well.

1. PSK A01 xpl-hi :黑: 白光- xpl-hi (CW- xpl-hi)
2. PSK A01 hcri :黑: 中白- 日亞 319 hcri (NW- Nichia 319 hcri)
3. PSK A01 xpl-hi:原色: 白光- xpl-hi
4. PSK A01 hcri :原色: 中白- 日亞 319 hcri

Here is a short test video for Manker PSK A01

Really like it with the bezel points backwards, quite the looker.

I googled the aluminum and fail to see why this is better for flashlights. The sturdy tests of Simon show that 6025 is strong enough and it has 40+% better thermal conductivity.
So what am I missing here?

17

The biggest strength of 2024-T3 for use in fuselage application (for commercial airliners) I think is damage tolerance; significantly lower fatigue crack growth rates than other common aluminium alloys.

It’s just a personal preference for the same reason people like titanium. 7075-T6 performs slightly less than 6000 series aluminium when it comes to thermal conductivity as well. In terms of strength, well, you could reduce wall thickness of the battery tube to reduce weight a weeny bit while maintaining same strength if you like. Not really practical, but just a possibility. I just like the alloy and the specs on paper a lot. :sunglasses:

Hi. New flashlight guy here. This looks like a good model to start my collection. Maybe not the place but count me in for one.

19

What’s the head diameter?

Looks a little short to be useful for prying out nails. :stuck_out_tongue:
