Thanks,do they ship to China? Price is good. I also conatcted Hank @intl-outdoor. Hope he has some.
I bought a TrustFire X6, will mod it with XHP35.
Edit: the shipping is killing.
i ordered from cutter.
just get over 100 $ 
It sucks if they use the one-month snail shipping.
Price:7.99
5.64USD (what is this for?)
It says Alum star? I thought Noctigon is made of copper.
mine was shipped with dhl (4 days AUS-AUT)
i bought the HI Version
one on a aluminum star and a bare one (had solder on the contacts - i think they took it off from a star )
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.
