It may be worth noting that Titanium is denser than Aluminum. So the same light will be heavier in Ti than in Al. (the Ti version will be much stronger/tougher though)
I highlighted the best and worst items in each category.
Maybe I’ll also add a “volume” category to try and quantify how “big” each light would feel in a pocket…
True, the Lux RC has the smallest length x width… but not the lowest weight, because it is not Aluminium
Measured at 31g:
That light had so much to be really good and it turned to be so not good :zipper_mouth_face: Sad…
Dont know where to ask…Please i need 18350 cell ..Any experiences with the REAL maximum capacity?? I need max capacity but no experiences with these cells.thannks
Keeppower 18350 1600mAh UH1835P2
Vapcell 18350 1600mAh H16
Positive end looks the same. I suspect they are the same battery. Both 5a CDR.
I’ve been using both for about 6 months.
does your light need Protected or UnProtected batteries?
I wanted Wurkkos TD97…i dont know…I like it so much,but the capacity…
you can buy 1600mAh 18350, that is 46% more capacity
and this review says unprotected flat top fit.. so you could use that 1600mAh vapcel
“LVP will be handled by the driver. I tried a long protected Manker button top 18350 and a standard flat top VapCell M11 in the TD07 and all fit just fine.”
But ultimately runtime will be shorter on Turbo and High, and longer on Low and Medium output. So its up to you to use an output that makes the battery last longer, or not.. this is true for all lights
runtime concerns are mostly solved by having extra batteries..
otoh, in this chart you can see that Turbo and High (Red and Blue lines) last about an Hour, but notice the output is not steady, it continuously goes lower.. for me, that is not good, and is a reason not to buy it
but, if its a light that interests you.., get it and have fun with it.. its not that expensive.. for more runtime, just get more batteries…
good luck w your decision 
Jon thanks a lot for this…But.i wanted to reflow this flashlight led for xhp50…And that led will be hungry like the wolf…I guess
that will make a wider beam… depends what you prefer
XHP50 is a 5050 LED, and wont match the 3535 SFT25 mcpcb… you could change the mcpcb, just be sure to use the 3V configuration
the SFT25 has a much smaller LES, for a more throwy and focused hotspot.. It is very nice imo..
the XHP50 has a larger LES.. more lumens but spread out wider… for tight focused throw I like the SFT25 better
either way, I hope you have fun with it
