That's pretty fast. Do you know what is the 5.64$ for? And is it an aluminium star instead of what the pic shows "Noctigon"?
Edit: Sorry, I just noticed that the HI version is on alum star. Is it a DTP ?
their prices are australian dollars 
so its cheaper a lot transfered to USD
for the other questions you have to contact Mark (username welight)
ah,AUD, thank you. It's an Aus based supplier. Price is really good, is it? the other stores sell the bare LED at 7USD,and no free shipping at all.
I bet the X6 would make a great host for the XHP35. Did you find an additional extension tube that will fit to make it 4S?
I had the same idea for my X7 but cant find an extension tube that would fit.
Damn, 3S could work, but not as better as a 4S. Will be checking TF if they can sell me another tube.
3S is not enough
not even with HE2…
3s is definitely not going to cut it. Not enough voltage to get any real power out of this emitter.
Couldn’t you just put in 4x 18500 instead of 3x18650? That way it fits and you get your volts without an extra extension tube.
He could, but then runtime would be fairly pathetic. The glory of this light is in its heat sinking and extended run time because of it…
What resistor did you use to zener mod? Still the 200r?
What zener and resistor did you use to mod?
Not sure if this has been asked before, when one uses a linear driver to drive the 12V XHP-35 emitter, wouldn’t the 4S batteries kill the XHP-35 immediately due to the extra 4V?
not really…
did you read my graphic?
for 3A that led needs 15V (when cooling is good it is surviveable i hope)
Yes I did read your test graph (thank you for that!), and yes I do realize that the Vf of the LED would increase as the current increase, but how about when the LED is in low mode (i.e. 0.1A or lower) while the Vf is still around 12V only?
Apparently the XHP35 is just 4 XP-E2 dies in series. So each die is seeing 4.2v, which we do all the time
I think that makes sense, thank you.
Anyone has tried to mod the Acebeam K50 with this XHP 35 emitter? The K50 does look like a good candidate for it as it has 4S batteries configuration and comes with a big reflector.
3000 lumens, possibly 250+kcd, and that really sounds like a HID flashlight.
Hi,
is this FET-Driver in 4S setup suitable for the XHP35 HI or will it get too much current?

in my test i DDed the emitter…
a driver just lowers the Amps at 4S…
maybe 4S2P might kill it 
The only change I had to make from the 2S board was to upgrade my 10uf cap from a 10v to a 16V. All my other components were already 16V or more.
Initially I ordered the 16v caps from Richard, but since you asked about the other components I updated my bom with a 16v cap. Here is the list. I have not tried the 16v cap in this bom yet, but it has exactly the values as the ones I got from RMM so it should work.

These are the boards I use.
