Lenser K3 Crazy Nano Aspheric Thrower -XPE 10280

Led Lenser K3, the smallest Lenser Focusable LED Flashlight is a tiny key chain light, about the size of 18650 Li-ion.



The head was glued, but can be taken apart with some efforts:
It's a 5mm LED run on 4x buttons, pretty useless combo when coupled with
a nice Aspheric lens.



It's pretty easy to recycle the pill, mounted with a XPE-Q5 on 15mm board.


Wired for Direct Drive:
I fitted in a 10280 li-ion, had to bore out the tail cap just a bit & took the springs out. I did manage to get it fit in there.


Finished!


So small:


Crazy Nano Thrower:


Wow!

Re: Lanser K3 Crazy Nano Aspheric Thrower

Nice mod, now if only you could fit a CR2 batt and a boost driver.

I'm guessing the bore dia is too small for a CR2 ??

Re: Lanser K3 Crazy Nano Aspheric Thrower

WOW great mod! :wave:

Re: Lanser K3 Crazy Nano Aspheric Thrower

:wow:nice size.:thumbsup:

diameter of aspheric lens?

what battery?

current draw with battery at 100%?

lux @1m?

why not xr-e? viewing angle xr-e :90 viewing angle xp-e 115

the chip its ez1000 or ez900?

I love pocket throwers with 14500 batteries.....your mod its really small oo:

Re: Lanser K3 Crazy Nano Aspheric Thrower

Nice mod. Did you do anything to increase heatsinking?

Nice "pocket Rocket". I assume you had to bore out the body a little too.

Can't fit CR2, the body is 14mm diameter, battery chamber 11-12mm.
CR2=15mm diameter.

Yes, by holding on it tight & transfer heat to my palm

No, the body tube/battery chamber is 11-12mm in diameter, no issues there
to fit 10280.

Re: Lanser K3 Crazy Nano Aspheric Thrower

Moviles,

Why do you always have the same type of projects with me?
First, the SST-90, then the pocket Aspherics?

I have 2 (the two on the left) of the 3 Zooming flashlights you had in your picture,
I can tell you that the K3 mod gives as bright of hot spot die image
but die image is 2x bigger than the DX lenser clone you have.
I am estimating 3-5x Lumen from K3 mod output vs. those two on AA.
Those two DX/kai lights were under driven when using AA in stock form.

More answers under your question:

:wow:nice size.:thumbsup:

Diameter of aspheric lens?

A: lens is about 16mm, the flashlight body diameter is 15mm, diameter of the head is 20mm.


what battery?

A: 10280 Li-ion

current draw with battery at 100%?

B: I don't know. It's DD without resistor.
Whatever 10280 can pump out to the XPE-Q5.

lux @1m?

A: I don't know, I don't have lux meter, but I can take some beam shots vs. your Lenser Clone AA
on the left in your picture & you can have an estimate? I' don't have 14500 li-ion, but I have 1.9V AA Li.
It'll be K3 Crazy Nano Thrower -10280 vs. Dx Zooming Lancer Clone - AA Li.

why not xr-e? viewing angle xr-e :90 viewing angle xp-e 115

A: I only have XPE-Q5 at hand. But I am not sure it'll be better with XR-E.
I heard that XP-E has lower vf, so pump more cutrrent than XR-E under 10280 DD?
I also saw a post comparing XP-E vs. XRE mule & stating that there's more light toward beam center
on XP-E despite larger viewing angle. It's how much light in the center 30 degree that matters, the XPE may
win on that?

Eitherway, it's crazy amount of throw!

the chip its ez1000 or ez900?

A: I don't know, I can't tell.

I love pocket throwers with 14500 batteries.....your mod its really small oo:

A: Yes, I like tiny lights with big throw power, AA is to big,
It's Halloween, people will see crazy lights coming out of my finger with no flash light

the three are modified :
the first of the left, c78 (copy of ledlenser p5):

it give 5800 lux@1m (stock)1xaa 1.2v
now i have it direct drived with 14500(no room for driver) and it give 14900 lux@1m at 2 amp (I'm lucky low vf)with 20mm lens

in the middle the romisen rc-29:

it give 6800 lux@1m (stock)1xaa 1.2v
now upgraded with sku 7882 it give 15400lux@1m with 14500 at 2.2 amp (at battery) with 21mm lens

on the right the romisen rc-g2:

with sku 7882 it give 15600 lux @1m with 14500 at 2.2 amp (at battery) with 21mm lens(the lens of the x2000 flashlight) i tested it at 2.75 amp and i give around 18000 lux the first seconds but i don't want burn the led and I set it at 2.2 amp



today I have seen the ledlenser k3 in a store at 10 euro in my city .

I maybe will buy it

but the big problem is the battery is of only 180ma/h and the maximum intensity recommended they are 360ma (2c) and we need 1000 -1500 ma (around 8c)

we will need 10280 imr batteries

Here is the comparison between:

lenser K3 vs. DX Lenser clone




Now, the beam shot
Lenser K3 10280 on left, Lenser Clone AA on 1.9V Enegizer Lithium on right.
The lens on lenser K3 is ~16mm. The lenser Clone AA ~21mm. Distance to the wall is about 12ft.

The Out door beam shots are up on post #2!
