There are actually two versions.
One is the 5A Linear regularted driver for the Osram, SST-20, XP-L LED.
The other is the boost 2A/12V driver which is for the XHP35 LED.
Yes, of course, I have tested both of them.
Stoked to see the boost driver! Thanks Hank
500kcd!!! Take my money interested! 
I’m in for this one. Love it, can’t wait! Thanks for the update.
Hank, can you offer a custom build with Osram Ostar Projection Compact LE R Q8WP (625nm) with up to 700lm of red light at max. 5A i.a.w. the datasheet ?
I have this LED installed in theAmutorch New VG10 (bought from Neal) and it makes an amazing bright red thrower. This LED installed into the Noctigon K1 would be great and should perfectly fit to the driver specs.
I’m a little sad this isn’t buck/boost or at least buck. I actually find myself contemplating XHP35 over SST-20 now.
Looks great!
I’m hoping for XHP35 HI CRI version then :sunglasses:
XHP35 3000K or 2700K hi cri for penetrating the fog would be great
I guess it doesn’t use Anduril because of the buck/boost driver, does it?
Yes it will only make sense on direct drive. The NI40 SBT90 pulls 22 with a 40T. Would really appreciate it if you could make a FET/DD SBT90 version :laughing:
Could also make it regulated but have turbo in direct drive.
That driver sounds great. Now put it in a right angle headlamp next, please. 
Do you know where can I buy this battery for lowest price?
Delivery to EU.
Thank you
Kind regards
Looks like I’ll be getting 2 lights
I sure hope these will come in green and blue to match my other Emisar lights.
Looks great Hank, a real eye opener that I will surely have to buy as soon as it’s listed! Somebody PM me when it goes on sale please so I don’t sleep through it. C? Wake me up man! Lol
So the Osram emitter will be getting around 1.5km throw, which is incredible. What kind of throw (and lumens) will the XHP35 HI version have?
I’d love a 3000K XHP-35HI version.
If the Osram/SST20 version was buck / boost, I would have had a hard time deciding which to get.
Based on the two options, the decision is easy for me, XHP35 all the way.
I hope Hank offers the XHP35 version with warm white 80 and 90 CRI options.
As others have mentioned, warm white penetrates fog so much better. I also find it adds contrast and definition.
Looking forward to see the numbers on throw and lumens. I suspect the XHP35 will be about twice as bright (lumens) as the 3V version, with similar throw.
