Noctigon K1 info / review

Just a thought, but for big lights like my D18 and Q8, you can grab some cheap LED replacement bulbs and cut the globe to fit. Pics to follow

You can now order the K1 with SST20 or XPL HI emitters

Thanks for the update!

Great news. Hank, what current is linear driver set up for XP-L HI and SST20 emitters?

Now all versions with lumen and candela infos:

W1 (Osram CSLNM1.TG), 6000K, 650KCD
W2 (Osram CSLPM1.TG), 6000K, 550KCD
XP-L HI V3 1A (1300lm, 290KCD)
XP-L HI V3 3A (1300lm, 290KCD)
XP-L HI V2 5D (1300lm, 290KCD)
SST-20 6500K (1300lm, 330KCD)
SST-20 5000K (1300lm, 330KCD)
SST-20 4000K (850lm, 95 CRI, 230KCD)
SST-20 3000K (850lm, 95 CRI, 230KCD)

The SST-20 5000 K should be a good tradeoff with usable spot and good throw.

Lumen values suggest that it’s probably around 5 A (i.e. the 4.9 A version as Hank wrote in this post).

Thanks for the cross post…

For a thrower, I see only 600kcd+ as an option…
In fact,I wonder if someone in the aftermarket will boost the 650kcd number…I haven’t bought one yet due to the new car, but it’s at the top of my list… we

Not going to happen, you can only achieve this by using a larger reflector

Any updates on the release of the XHP35 version ?

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 :wink:

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.
