I knew I recognized those cut outs on the handle there. That fandy is on my ‘buy when I win the lottery’ list.
This is a little tuffer. It will run off a 26500 if you bore out the tail cap and side clicky housing a bit otherwise a 18500 with a sleeve goes in without boring. OAL is coincidentally to the Fandy/DST is also just
6 1/2”.
Feels really great in the hands which IMO is helped by the side clicky. Everyone that picks this up goes, Ooooooooooooh!!!
Looks like a shortened version of the standard 3C Defiant light. ( probally using a single 26650, 18650, etc. ?
Yup, he nailed it. Almost. It’s a 5C. So all ya gotta do is somehow find a 5C Defiant that can actually be taken apart from the tube and then just thread the tail cap to the side clicky part which threads perfectly. And voila! You now have a compact little blaster. Especially de-domed. :bigsmile:
Most of the 5C Defiants btw are stuck together with nitro glue.
Interesting 
i have one and never thought about trying that. What cell are you using ?
nice
Any guesses at this one ?
Sipik 98 head mated to, to, to…….
You have one part right of the two.
The Defiant AA!
I have done the same. Sweet setup.
EDIT: Ooops I spoke too soon, although that works too
This could be a tuffy. Well maybe not for Lego-King DenBarrett. 
I should be disqualified from guessing, but I will anyway. Ultrafire SG-R13 tail and one of the many decent C8 heads available on the market.
You guys are good. 
I had an unfair advantage. You recommended that combo here. I remember because I purchased the SG-R13 on that recommendation. I have not performed the recombination yet though.
but what the hey a darn good calculated ‘guess’ is better than pulling it outta somewhere dark! I think you’ll like the setup.
This one should tweak a few frontal lobes. hehehe
Then again I’m dealing with some pros here.
Is that one of the solarforce L2 heads?
Tuffy is as tuffy does. :bigsmile:
It’s a Defiant 2 x AA head which has now been discontinued. They were clearanced out at just $4 in a two-pack for awhile there. Great all-time bargain deal indeed. The drivers alone are worth it. Old-Lumens did this thread on it……
Its boost driver is neat in that it’ll run off a single 1.2V, AA, or AAA eneloop, alkaline, on up to a 14500 and has three modes with an always turn back on to high and is quite efficient. The XTE emitter IMO is underrated (and often ignored) and yet performs deceptively bright out of this OP reflector. Strobe particularly is blinding as all get out. De-Doming gives it that little extra throw.
The tube and tail cap is from a cheapo Small Sun ZY-203. OAL is now just 4” including the crenalated bezel. Everything mates up nice and tight as if factory produced. Put a clip on it and you have an even cooler little lightweight setup.
I put two o-rings on the tube to give it an extra easy handling tail cap switch. O-rings used like this really transform many lights into being much more user friendlier. Try it and see for yourself.
