There is a coupon from m4dm4x too . 
I can’t find it. I saw one from Freeme. Is that who you were thinking of?
The short tube is listed now. I’ll add the link to the L2/L6 modding thread and the OP here and in the L2 thread later with the additional details.

Hi Djozz, which batteries do you use? My L6 is from fasttech and with r100 and fresh liitokalas this at 7.1 amps + - greetings.
I will do another measurement, I use the same 5000mAh Liitokala’s.
Well, try sanyo ga, kill two liitokalas doing shortcut, a stupid mistake on my part :person_facepalming: , with fresh sanyo drain very fast, start above 7.3 amps and immediately start to go down so this battery is not enough for Feed the modified L6 but it serves as a sample, greetings !!
I fully charged the Liitokala’s, used a thick magnet between the two batteries because they are so short that they do not really push on the springs very hard, and it is much better: 6.6A using a small copper coil with clamp meter with the tail taken off, and 3800 lumen at 30 seconds with the tail in place.
This is with the added R110 in parallel.
Maybe magnets, produce resistance? R110 less than r100, that may be another difference in performance
Some magnets are coated with a protective layer. Even if it isnt, there may be a little resistance in it. I use solder blobs on my 2 liitokala that I use exclusively in the L6.
The 2 stock R082 resistors create 0.041 ohms.
Adding a R100 drops it to 0.0291
Adding a R110 drops it to 0.0298
So pretty much the same.
then when i use it in L6. can i use 1*26650 ? or use for 3*26650?
I thought the purpose of the short tube was for fitting 2 x 26350 cells. Right? Wrong?
… making for a shorter easier to carry light, though with a reduced run time.
I thought it will have the tactical ring
Heyhey,
Got my smooth reflector for the L6, but damn that’s an ugly beam now. Does it get better when you shave the dome, or even worse?
Hahaa!! A little Ringy is it! Better/Worse? The Answer: It’s for those who know and you to find out!! 
smo reflector begs for xhp70.2
Thanks! I didn’t see that.
I’d say you have the same beam pattern, it’s just more intense. Why did you buy the SMO, I hope its not for pretty beam shape. Lol
It does give a big jump in lux and distance, but you have to play with the distance from the emitter to get a smoother hot spot.
I’m kinda digging my shaved dome xhp70 with the OP reflector. It’s definitely a tighter “pretty” beam. Still has improved throw, too.
My xhp50.2 should arrive any day now and I’ll try it with the SMO reflector.
He responded to this same question on the L2 and L6 mod thread. I just copied it here.
If you look at the L2 reflector base and compare it to the L6 you’ll see a couple major differences. I do believe a narrower, thinner base helps, You will also notice the angled interior base on the L2, a smoother transition going out into the reflector, then the straight angle base of the L6.
With the XHP50 L2 build I just shaved the reflector base paper thin and the hot spot is very tight and clean, with just a faint very narrow ghost ring of a corona.
The XHP35 HD L6 build, I hazed or diffused the base and up the reflector to about 2-2.5mm, the rings are still there ever so faintly, on the WALL, but outside, nothing! At 3+ amps I have no doubt the XHP35HD E4 3C is putting out 3000 Lumen, pretty impressive high out put big beam thrower!
Notice how thick the base still is, even after filing half of it away, you notice it more when it is sitting on the board! It’s good enough for 
now……
