LOL, BLF minds think alike, was looking for that board as well. The only seller that has the Maxtoch boards a bit cheaper ($3) is Banggood, and they are out of the 26mm XP version.
That is fairly cheap source for USA citizens. But unfortunately Europe does not have that kind of vendor. So we depend on slow boat from China.
But I also know that Mitko has incredible knowledge in finding electrical stuff for cheap probably because this is part of his daily job and he for example managed to find old school XP-G2 S4 2C emitters and shared the link. BTW Mitko did you spend them all already? I managed to get couple of them and than when I found that they are good old ones and when I wanted to order more they disappeared.
Btw S42C is same in performance like S32B but tint would not be everyone choice. It was really something magical in performance of old S42B that disappeared into oblivion.
I checked in my stache and I do have 4 S42B that I bought from Richard ages ago. Still in the little baggie and marked as he marks them…. still in the tape. So those 4 are confirmed, I’ll just have to find out what was in my Meteor and see if I can find those. I used to use 2B in virtually all my triples before the XP-L HI came out so who knows what I have around here.
I just opened the head of my modded Supwildfire with Black Flat again because I wanted to see if I could center the led just a bit better. And not only did I manage to center it slightly better (almost but not quite perfect now), I have now closed the bezel fully which feels better too.
Of course I could not resist measuring throw again:
30Q battery at 4.13V, measured at 7.000 meter distance, 30 seconds after switch-on: 353 kcd. So a tiny bit better
So it does 353 kcd, not fully charged, 30s waited (I usually cheat there ), and might actually be better at 10+ meters. Dang! How do you rig up those Black Flat's being the center pad has to be electrically isolated? You seem to have a pretty good setup there.
I might want to try one out in the BOSS1... On 4P of LK 26650 cells, can they take the amps?
Of course! VTC5A's are the best 18650 DD amp cell on the planet, as far as I know of.
Think those Black Flats have a peak amp range though - too high may drop off.
The solution was: no driver. The ledminus is simply in contact with the body via the DTP-pad. 1 time reversing the battery will blow the led.
That is why I ordered another one, to make a dedomed XP-G2 version with a proper driver.
If you really want to use the Black Flat with driver, I think that the way to go is to sand down the rim of the pill level with the ledboard shelf and use that tape (dunno the name) that you use instead of thermal paste to stick a 26mm Maxtoch board on top of it. The large contact area between board and pill should be enough compensation for the relatively poor thermal properties of the tape.
The led draws 5A now, and that is right at the peak output of the Black Flat that I measured. So the output curve is so flat there that it takes a fair while before the battery is so drained and current so low that the output really suffers.
The VTC6 will only make the output worse, you end up over the peak output.
Interesting statement there Tom… I have tried the VTC5 in multiple lights and it gets beaten by several cells. My Ti X6 Quad 219C pulls a bit over 21A on an LG-HE4, no other cell can match that. I’ve got lists of up to 16 different cells in the D80, the VTC5 isn’t on the top. All this means is that different lights perform at their peak with different cells, like finding the correct powder and bullet combination for a given firearm. There are no constants.
Edit: Feeling like crap and still saw that this sounds combative. Not intending it that way, just merely saying I haven’t found any one cell to stand out over another in an averaging of lights tested. Could be my results differ due to different light styles and testing methods. Sorry I’m sounding so grouchy.
Ohh - fyi. The VTC5A is the cell Mitko uses for quoting all his high numbers. Though a 3000 mAh is more useful for the full drain, the VTC5A does great for the first 30 secs
Shoot - measured 26A on proto #1 with the XPL2 V5 4000K LED's, but that was on 30Q's @4.19V. Noticed I didn't try VTC5A's in it yet
