Boost HL could top that. But not by much.
Manual focusing might help some…or not.
Is there like 2% to gain by using UCL2 or a similar lens?
Am I missing something?
Anyway, that’s not much. There are very few stock lights as close to the limit as this one…
In the TLF we got some outdoor beamshots (probably requires registration to see the images in full size): Noctigon K1 | Taschenlampen Forum
Awesome pencil beam. Looks like a lot of fun, but not so useful for real tasks.
Nice beamshots, made an account registration for those 
But you are completely right, i have a L21A with white flat and 5A driver, does about 550+ kCd so its very compareable, its real fun, but not very practical (or should i say useful ?)
Thanks for posting this! I’ve been waiting for some outdoor beamshots.
Thats a good idea Zed, especially for a lantern. I ended up ordering the silicone diffuser from banggood.
I’m not sure how popular these other emitters will be. 290KCD is still very impressive but I bet almost everyone will order W1.
I won’t order W1. I find cool white throwers have more visible backscatter, I don’t find ultra-tiny hotspots all that useful, I’m tired of linear drivers, and I haven’t yet found a light that throws far enough to make me stop caring about CRI.
I’m waiting to see how the XHP35 HI model performs, especially if Hank sources some of the 80 CRI Easywhites, with which I’ve had very good results in other lights in 4000K and 4500K. Barring that, I’d consider SST-20.
Yet none had any linear driver until K1.
All of the Emisar lights use Linear + Fet drivers. The Linear part of the driver is responsible for the regulation which many of us seek in a light.
I believe Zak’s comment was extending beyond the Noctigon line of products, and I too agree, waiting to see more buck and boost drivers and limit my purchases to these flashlights as well.
And you are absolutely right!
Waiting for the XHP35 version as well…
What can we expect from the XHP35? More lumen and less throw than XPL-Hi? Maybe alike 4000K SST-20?
Compared to XP-L HI - more lumens and similar throw.
So what would be the reason to get the XPL-hi? No tintshift?
XP-L HI doesn’t have a tint shift either.
The reason would be more lumens and therefore wider beam.
Yes thats what i said 
I meant: what i the reason to take the XPL-Hi over the XHP35? I don´t see any. If throw and tintshift is comparable and XHP35 makes more lumen, i would always choose XHP35.
Ah, right. 
XHP35 HI doesn’t have a tint shift either. I guess the main reason would be price.
ADDED:
Maybe tint selection as well. Maybe longer runtime / turbo time? XP-L will surely not need a thermal stepdown. XHP35 HI might.
The no-PWM linear driver in the K1 should be a bit more efficient than a 7135-based PWM driver. If the 7135 design has multiple channels though, it’s only a small difference.
A direct-drive FET is also frequently a nice addition, to increase the maximum brightness on lights which can actually handle the extra power. It’s mostly just for turbo use though.
Compared to a linear driver or a linear-plus-direct-drive hybrid driver, a boost driver typically is more efficient in the medium modes. However, it’s usually also not able to go as bright as a FET turbo, and tends to be less efficient on really low modes too. So, not as good for moon or turbo, but usually more efficient at most of the levels in-between.
There are some known cases where a boost or buck driver ended up being less efficient, like how the Lux-RC 371D driver is ~30% less efficient (even in medium modes) than a simple amc7135 driver… but that doesn’t seem to be the common case.
Yes, the difference is the driver, since it’s 12V the driver needs additional components which makes it more expensive than a regular 4V driver.
The XPL-Hi and SST20/40 are easier to drive, that will probably be the reason they are already available.
But the difefrence between SST40 and XHP35 probably won’t be very much, apart from the fact that the XHP35 HI will throw farther since it’s domeless and does not experience the bad tint of SST’s
A wider beam (The Osram throws like hell, but the hotspot is very tiny) a better tint, more efficiency, more usability, that’s my main reason to wait for the XHP35
I’m a huge fan of lineair drivers, simple, cheap, small, do the job more than adequate, very robust/reliable, efficiency is fine. And although it has not been proven to occur often, I fear for voltage spikes coming from drivers with inductors (I had a precious 90CRI XHP50.2 killed by a KD boost driver).
Yeah linear up to 1Amps in D4, over that is direct drive in D4, but not 5A linear or 8A linear drivers, quite a massive difference.
So, out of curiosity I noticed a fair amount of people on r/flashlight have been mentioning getting shipping notice for the lights going out as early as the 30th of November as well as receiving the light in the mail. It maybe my paranoia but I also placed an order once the K1 dropped on hank’s site and my order and payment has been confirmed almost 12 days ago by paypal….
Am I just overthinking things or have I been overlooked or missed in the shipping of the light ?
