Hank if you see this thread we would love an update on this project 
Yes, we are still working on it, here is the prototype photo, it’s not called D1SV2, it’s called Noctigon K1,
with fully regulated driver, it should reach 600+kcd with CSLNM1.TG LED, there will be green/red
beam version, as well as XP-L HI/HD LED with different color temperature.
Beautiful!
This looks like it will be a killer light!
What battery does it take?
21700 with the 2A type-C charging port on the threads.
Both are excellent choices, thanks.
Now I just hope you test an aspheric lens/bezel for it like I emailed about. Maybe asking too much
Looking great! And it you cover the reflector part it looks like a regular D4 
Hank that looks amazing!
Are there different tint options for the CSLNM1.TG LED or only CW?
Thank you for the update.
WOW!!
CSLNM1.TG is only available in cool white, around 6100K typical.
I thought I heard some warmer options were popping up, maybe that was the CSLPM1.TG 2mm?
Awesome.
Integrated USB-C charging is awesome, it will directly compete with FT03 
Awesome! This would be my first CW thrower. And my first 21700 light… Waiting for the specs for the other LEDs. Hope it will be below $60.
I think I may need one of these, with a 4000K SST-20.
Yup, I have a collection of FW3A pulls and one will definitely be going in this light.
I also hope Hank will release an aspheric kit later on. Prometheus/47s just released an aspheric kit for their quark. That would be amazing for this light.
What size is the mcpcb? I hope it will fit a SBT90.2.
21700 and USB-C is the thrower I’ve been waiting for :+1:
Also hope there will be a SST-20 2700K or LH351D shaved dome version. What the market lacks is a WW thrower to cut through fog.
Looks amazing! better than i thought. Please make an SBT90.2 version as well. We’d all love to see it. It’s 3v as well so the driver should be cheap and easy to manufacture.
