A quick footnote. My neutral aluminum set came. One box a little smushed, x5 clip too tight to work on much. Otherwise very nice so far. Haven’t found any major flaws. Great deal for price paid.
Patience 
If they think they can sell reflectors they will make some.

I just measured the voltage drop of the X6 tubes, With the CU head and SS tail cap and tube I got 4.9 mV, from the tail cap to the head, with the copper head, the AL tube and the SS cap I got 6.8mv. I don’t know if that is just the contact resistance or if it is because the SS tube is a little bigger.
So am i just sooking or is any one else x5 like mine? I didn’t say any thing to banggood cause i thought this is normal? it has other spots also…

Inteeeeressssting, we now have TK's & Joat's results giving us consistent indication that the X6 SS/Cu light's body has a lower resistance than the Al light's body.
?This may be due to:
- Better contacts for example at the battery tube interfaces with the tailcap &/or the driver (we can try to minimise this for the Al light by sanding off more of the anodising at the contact points)
- &/or the effective cross-sectional area of the SS/Cu tube is much greater, so that it more than makes up for SS's higher resistance.
- Or?

My Cu X5 lights also had measles 
, but I was able to remove the spots by using a very slightly abrasive cloth followed by a microfibre cloth.

I wonder if they will sell switches or switch pcb at least so I can convert some of my lights to lighted tailcap.
does the aluminum body give a lot of resistance to the current.?
200 lumens is a huge difference
will modders start doing a body bypass along with a spring bypass ?
I expect there will be fairly wide variation between individual units. Some may get 1200 lumens while others get 1500 lumens. My guess is that these differences are mostly random and won’t correlate strongly with the body material, but I don’t have anywhere near enough data to determine that. I’m just guessing that other factors are likely to matter more, like how well the driver was soldered and whether the tiny individual components were near the top or bottom of their spec bin.
If other people have both flavors of the light and the ability to measure lumens, the additional data would be welcome. Not much can be concluded from a single data point though.
Thanks for creating these awesome lights.
The ALU set just arrived
Cardboard boxes OK
Reflectors shiny as they can be
Taillight not too bright
Did not dive into the Bistro they came in 7 mode
The X5 is very impressive so much light coming from such a small thing
The X6 also has nice light but non of my high quality cells fit so I have to use a 1200mAh 125mR (according to my Liitokala) Ultrafire cell.
Please recommend me a good protected a brand cell (the Panasonic and keep power do not fit, will try the only unprotected cell later (KeepPower))
Ah nvm the 3168mAh 31mR unprotected Keep Power fits nicely
And the clip of the X5 is tight but I really like that now I can have hanging outside my pockets without fear of losing it.
Thanks!
Thanks, I followed that thread but I know Oshpark is in the US so I expected hefty shipping costs. Apparently they ship for free if you are not in a hurry.
I don’t really know, but I hope so. There are more people who want to use a lighted switch than there are people who are willing to build one.
However, be warned that many drivers will not work correctly with a lighted switch. The driver must either be designed for it, modded with a carefully-chosen bleed resistor, or running an ontime-based firmware. And even in the best case, the efficiency in moon/low modes will be reduced (quite a bit for moon). But when it works, it’s pretty neat.
Uli, PM me. I might have a reflector you can have. I made my SS/Cu a Triple so I’ve got that reflector.
And yes, the 9A might seem low on the triple but it’s primarily because I used a lower binned 3D emitter for the quality of the tint. 
Those “measles” are the coating wearing off and the exposed copper tarnishing. It’s what coatings do.
I love the wow factor of the copper X5
I’d also LOVE a simple 2 mode (NW 500 lumens max) pill that I could swap out when I want to use the X5 for normal daily functions.
Anyone build or thinking of building an everyday use pill w/NW emitter for this X5 yet?
I you just switch it to muggle mode you’re very close to what you want without swapping anything.
It takes it down to just three modes with the highest mode at approximately 688 lumens.
According to the Bistro firmware write-up the three output levels in muggle mode are approximately 5 lumens, 163 lumens and 688 lumens.
I’ll bet if you put a non high-drain cell or maybe a protected cell your ceiling may only be in the 500 lumen range. Just a thought…
That’s good thinking.
I may get a decent bit of run time on a protected cell in muggle as well.
I’ll try it…
Thanks for the idea.
Hmmmm, in my 2 Cu X5s that was not the case, as when I wiped them (as I described) there is/was No visible coating defect Nor is there any visible tarnishing.
Btw, following your suggestion I checked them with a magnifier, & then with a low power objective/lens in one of my optical microscopes (to be sure, to be sure 
). And the coating does not seem to have any sizable defect(s).
Best Regards,
George
OOH MAN! These Alu X5 and X6 are so NICE!
That small cute blue buttoned X5 with its tight clip looks so innocent hanging on a pocket.
Untill fired up and put on highest BAM more light then a Convoy C8
I love the Bistro firmware.
normal half press moving up through the modes, and longerhalf press for down
So cool the lights can tell what the voltage of the cell is.
Only turned the memory on, groups were nice as they were.
Thanks Toykeeper!
Overal building quality excellent, finish perfect, AR coated lensen, so neat they are like the same light only the X5 is washed a bit too hot
To be able to play with the reflector placement thanks to the screwthreading.
Thanks design and test team!
Those reassuring blue switches, telling you where they are and that they are ready to fire up.
Thanks Pilotdog68!
Everything looks good, those little details like X5 and X6 on the clips good fitting box
Nice threading.
Thanks manufacterer!
Packaging was good, protective foam around the boxes inside a padded envelope.
In the end not too long in transit.
Thanks Banggood!
These two are impressive and just great fun to use.
But now I am off, the cells still have some juice in them so I got better things to do then sitting behind the pc! #gottopressthebluebuttons
