Review: CK36 Recoil Thrower

Ebay changed their search engine a while ago and wildcard searches no longer work.

Is your Fasttech version indeed able to run on 6 volts? Description says 18650 or 2 x CR123A. I’m wondering whether this driver can also handle 2 x 18650 with an extension.

All other recoils I currently see advertised don’t mention anything other than 1 x 18650.

I cancelled the ones from FT before they shipped and picked up two of the no-name versions from ebay, but they won't be here until tomorrow.

Most '3-4.5v' drivers will tolerate 2x CR123A (only 3v each), even 105C/7135 drivers are fine with it. RCR123 or 16340 would be a different matter altogether.

I also have a reflector telescope but its tiny at only 4”. I wonder if my addiction to flashlights would be severe enough for me to decide to convert my telescope into a recoil thrower. :Sp

If I have a 10” reflector, which would cost a fortune to acquire, and convert it into a recoil thrower then I know I’m already a total wacko on flashlights. But on the other hand, a 10’ reflector should produce a very powerful beam that would beat the hell out of most, if not all, of our throwers. J)

Thanx citruspers for this review and for introducing another insane idea to my already demented mind. :bigsmile:

this one is very similar with the one in OP but no description about the emitter type.

This light is designed around the xre, I have never one with a different led.

I have asked the seller and will update if receive reply.
lately light based on xre has been swapped to xpe by manufacture. Maybe to keep the brightness vs dollar balance…anyway this will be on my next purchase over the jacob. Just like the other design mechanism :slight_smile:

Did you contact seller lightupfoto? They said the CREE is T6, which means it’s XM-L?

yes I did,
first question was XPE Q5 or R2 or XRE Q5 or R2. at first they replied T6.
I reconfirmed again if it is XM-L T6 or else. they revised to Cree Q5.
Now I’m in the process of question number 3, XPE Q5 or XRE Q5 :smiley:

Thank you for persisting! :smiley:

eventually they stop replying, so Cree Q5 is what we got :slight_smile:

Someone should try an XML, a high current driver and liquid cooling. I probably won’t be the one. I might try something similar in plastic. The XML will compromise the throw, making it less of a demonstration and more of a useful light.

Hi guys, just a little update:

I’ve modded the light to direct drive, and it now draws 2 Amps :bigsmile:
Spattered some heatpaste along the aluminum housing, but I doubt it’s going to help that much. Like a true flashaholic I’ve now created a rediculously bright compact thrower which will fry itself if I leave it on longer than a minute.

Burst mode it is! :smiley:

Does it really get too hot after only a minute? Any beam shots? :bigsmile:

You could try filling the head with oil or alcohol or other non-conducting liquids. That would conduct the heat to the outside, independently of the awkward location of the emitter. I have found that silicone survives immersion in alcohol better than epoxy does.

How far in distance does this light tthrow stock? Beam looks neater than zoomies.

Stock…quite a bit. Can’t really give you anything solid though, aside from the beamshots.

My CK-36 throws 250 ft stock, possibly more (I haven’t tested it extensively). I would like to try direct drive now. SK-68 clone on eneloop can manage 100-125 ft.

I had to try direct drive, some improvement but I wish it could be brighter still! >.< Maybe I need to replace the thin wires and PCB spring? I want to try an aspheric lens too. S)

Mine doesn’t seem to get very hot either but that is less important. :smiley: From a freshly charged Sanyo UR18650FM it pulls close to 2A.

The die pattern is clearer/more focused now as I pushed the brass pin further into the aluminium “arm” after I took out the emitter PCB from the aluminium housing to apply some thermal compound.

Here there is noticable 1mm or maybe more, pre-mod. The wires prevent it from being flush:

After:

What good would an aspheric do with the emitter facing backwards?
