How do you plan to power the XHP35 in the S41? It runs at 12V and the S41 is a single cell light. So you would need a boost driver but I do not know of any boost driver powerful enough for that.
I thought about that as well but I the XHP50.2 will not fit the S41 optics.
I wonder if dedoming or slicing the dome would make it fit?
Plus I guess you need a mcpcb that fits as well.
Possible but the opening is so small I would guess even slicing the dome would not work properly with the stock optics.
The mcpcb is the real issue, it would have to be something really custom far as I know.
my apologies. Yes, XHP-50
I’m not certain it fits but should be close:
This same mod w/ these LEDs would probably be good.
I thought the xpl and xhp50 had the same footprint. I must have been mistaken.
Yes, they have the same footprint but different voltages. The XP-L is a 3v LED but the XHP35 is a 12v LED.
The xpl, xp-g2, Nichia 219 footprint is 3.5mm x 3.5mm. It’s a single die 3v.
The xhp35 footprint is also 3.5mm x 3.5mm, but it’s a quad die wired in series for 12v.
The xhp50.2 footprint is 5mm x 5mm. It’s a quad die wired 3v or 6v/12v.
The xm-l, xm-l2, and sst-40 are also 5mm x 5mm and single die 3v. You need this XM sized footprint to mount a 50.2 on.
I thought that 3V XHP50 is something like a unicorn, something rare that you’d not find anywhere. I got Xanes 1287 zoomie that has XHP50, but one of the segments is dark. So I decided to replace it with XHP70.2 that I had laying around. On the MCPCB in the 1287 is written “6V”. I put there new MCPCB with XHP70.2 and… nothing happened. I’ve checked it with multimeter and it was 3V, not 6V. So I’ve checked the removed MCPCB with 3V and it lit. Xanes 1287 uses 3V version of XHP50 in that cheap zoomie. It was quite a surprise…
There is no 3v xhp50. Only this new xhp50.2. Xanes is not using a Cree xhp50. They are using some cheap 4 die emitter.
Xanes lies about their lights and their batteries.
PS, there are also imitation xhp70 on the market as well.
I put one of these in the new Convoy S11 host. It has a Mtn FET driver and a 5,500mah Shockli. Quite bright.
Does anyone know if there is a 32mm triple or quad board for these?
Triple tpad for c8f, yeah. Cutter has it in the 3v emitter listing or all by itself: MCPCB-XML_XHP5032_TPAD - Cutter Electronics
Fits the light (21700 variant at least) pretty well. kawiboy modded one in this thread a few pages back.
Only quad I’ve seen is the q8 board that l4p has. led4power 38mm though
I have one in here too with the q8.
Ah beautiful…thank you! I think that one from Cutter is just what I need.
I know you said you liked this light IRA NightWatch 26650 flashlight, with a de-domed SST-40. How about a mini review for a newbie. I have this light with a XHP 70.2 smooth reflector ( I am partial to throwers and cool white). Just kinda wondering how it may compare since it has an OP reflector.
Thanks in advance.
My IRA has a smooth reflector for the de-domed SST-40. I thought I was going to mod it but I haven’t, like it pretty much just how it is, even with the odd UI. I’ll get around to modding it someday probably, usually do. I just like it’s style, the build is solid, neat light with nothing quite like it out there (that I’ve seen) At this point in the game, unique holds a trump card. 
You must know someone there, I sent them a message asking if it was available with a smooth reflector and they said no. I guess that I could order it and then order a separate reflector.
So lets summarize where we are
3 tint bins across 2 flux bins @ Cutter
2 tint bins across 1 flux bin @ Kaidomain
1 tint bin @ ASFlashlights
Anyone tested voltage for J4 vs K2 flux bins or event tint on any of these for that matter? I don’t really trust Kaidomain for obvious reasons.
I assume no changes in dedoming but it would be nice if someone ends up doing it to measure lux and kcd before/after and see how it cleans up the beam. Each bin seems to vary in this respect.
Can this really go in a SMO reflector with no donut?
