KC1 keychain light is available now

We do have the option, only that SFT-40 LED is not available yet.

Only that the throw is not that great, I measured about 25kcd throw on high.

It’s the throwiest of all Nichia’s so let’s say it’s a good one

It’s actually right on par with a maxed out 219C, which believe it or not is the previous ‘thrower’ of the 9050+ Nichia’s. Due to the quad die structure, the 219c might eek out a win.

In the end, I think a quad 219c under ledil angie vs b35am under 35mm single optic is going to be an interesting comparison.

D4S vs DM11. These are my estimates, some of which are based on Hank’s previous comments or specs on intl-outdoor

Max W 60 vs 22.5
Max kcd 20 vs 25
Max lm 3000 vs 1550

kcd @@ 20W 11 vs 24
cd/lm 6.7 vs 16
spot angle 18 vs 11

I know this is Blasphemy to mention another Brand, but there is another popular light with a 35mm head, single optic, with slightly frosted center that uses the xhp35 HI, that is only capable of 22,500 cd (with a 5500k emitter mind you).

All of that to say - if the BM35a is as nicely tinted as i am hearing, and the CRI is high, then 25kcd is actually rather good i would say! considering all of the information.

What will the throwiest LED offered be on launch? I was planning on ordering it with the SFT-40, I’m afraid it wont offer much over the KR1 other than aux if it doesn’t have a more impressive emitter than the W2.
Any idea if the flashlight will be released in the coming 2 weeks or not?

I don’t remember where I saw the post on the buck driver, but it’s what made me interested enough to post. I assume it was on BLF, but I occasionally check Reddit for news on Hank’s lights. Anyway, Hank said the DM11 would use the same boost driver that was already used on the XHP35 Hi K1.

Hank do you already know what will be the throwiest option for the DM11? Will it top the KR1?

The throwiest option will be Osram CSLNM1. If it’s driven to peak brightness (4-5A) we should see ~160kcd from it with this optic. The beam should look virtually identical go Acebeam E10 and Thrunite Catapult Mini, it’ll just be a little brighter hopefully.

KR4 tint ramping version is available for now,

D4V2 tint ramping version will be available as well.

Awesome!

Awesome. Is there a D4v2 or do you only mean D4sv2?

there is now a tint ramping D4V2 (source )

Just got these today! They are great! Thanks Hank!

Ugh! What LEDS to choose! I’ve settled on 2700K Nichia 219B. But for the other channel. 4000K 351d? Sst20? Or 4500k Nichia 219B?

I think 2700/4500 219b sounds like the right answer. 4000/2700 sst20 is also nice.

Do you think it would be odd to mix emitters? Nichia 219B and sst20 or 351d?

Different beam profiles, I don’t think it’ll blend nicely.

I wonder how the LH351D with its higher forward voltage performs with just two LEDs and the linear driver.

219B 2700/4500 or LH351D 2700/5000? Efficiency, max output, throw? How do they compare with this driver?

The 90CRI LH351D has similar Vf curve to the SST-20, see maukka’s tests : Samsung LH351D color testing - #12 by maukka

Well at least this sample, and another I checked myself.

I don’t see the LH351D in the menu though ? Is it a special request ? I don’t know what CRI is offered.
