Come to think of it, I would like to see this led in lots of lights of varying sizes, especially if they are built with proper heat transfer/ sinking to all of the body and head.
The problem with the k75 is that there is very little heat transfer from the switch section where the led is mounted to the quite large head if the light. That makes it get hot way too quickly to use for long term searching on turbo.
My plan is to do the same thing to it that I did to a very hot rodded k40 i had- strip the anodizing from the corresponding Male and female threads of the head to pull connection and re- assemble it with lots of high quality thermal paste. It made a huge difference in heat transfer, and therefore quicker cooling, in that light.
Ideally there would be a light that had a one piece head and pill section, with proper fins going all the way to the bezel, tapering in depth as they get closer to the bezel. This NL 40 looks like that sort of construction so if they just scale it up in size…
I actually think it will hit above 220kcd. Around 300 kcd and 4000 lumens is my guess.
I have a nl40vn with a flat white 2mm.
It does 320kcd
Can I ask, what driver you are using? Does it has his own driver specific design for ? I mean booster?or buck?
Sorry I don’t know what driver Vinh is using. He uses his own vn or vnx drivers. I believe him and Richard from Mountain Electronics produces them. But I opted for the single mode version.
If you look sbt90.2 in this thread and the other(I forgot where), it claim outputing 4000lumen and at the same time, guess the candela? 320kcd or roughly above 300kcd. Isn’t that great if it was true…
It has long thrower and higher lumen, the beam comparison look like it has larger hotspot with greater intensity…to put thing simple, it outhrow xhp50.2, sst40 and probaly the larger hotspot in long distance you’ve ever seen, Unlike before…sorry, just my own opinion if you dont mind.
Price $30-40 for sbt90.2 bead. Host would probaly gonna cost another 30. Erm sumarise all I think we’ve got rought $60-$80. Wew exPansive stuff…

Just a thought, I don’t own but one 26650 light, a Skylumen Delta and it’s only responsible for pushing 700 lumens so I wasn’t too familiar with the cell. Thanks for your input!
This LED should be combined with a larger diameter reflector for even better throw.
80 mm would be nice.
To me size/ weight matters. I’d rather have a nice thrower/ flood combination light with an emphasis on throw in the palm of my hand than have to carry a large reflector strapped over my shoulder. Those lights that throw 2 or so miles exist but for most people are just a conversation piece. Human eye can hardly gainfully and tangibly make out objects at that distance to make difference. I vote for keeping head as small as possible , but enough to provide impressive throw and dissipate heat.
The one with a large reflector can always be a different version of it…
I agree, I’m actually searching for the smallest SBT90 or CFT90 high output thrower I can find. This is the smallest one I’ve found, which is why I am interested in the purchase! At a 53mm head, that is the maximum I would want for jacket carry.
The diameter of this light is only 53mm…that’s not that big….and for it to get past 200k LUX, with a ton of lumens!….. that’s amazing. This new LED is a rockstar.
Think about it this way. What would a sliced and diced 3 volt xhp50.2 do in this 53mm head??? 80k LUX @ 3400LM??

Yeah, that’s what attracted me to this light, the smaller pocketable head size. That also usually means that the light should have good bright flood along with the throw. I’m hoping what others are saying turns out to be true, that the throw could be in the 300k area, that would be outstanding. I usually like a side clicky, because it just feels more natural when holding the light, but that’s not a deal breaker for me. A couple of my friends that are cops told me the department requires them to carry rear clicky lights now because in a panic situation, the rear button can be found easier than a light with a side button.

This is ridiculously cheap. The emitter in itself costs like 40€ when bought in bulk.

26650 i think.
can someone say compared to a xhp70 or xhp50 emitter, what makes this different and why is it so expensive?

When do we get to order?

80 mm would be nice.
Interested in purchasing! Put me on the list
thanks!
I agree, I’m expecting 300kcd. That’s serious output!
But can a 26650 run 4K+ lumens very well and efficiently on turbo?
why wouldnt it ? a 26650 highdrain can easy run a d4s quad emitters no problem…

Dunno why ppl are expecting 300kcd. Max it will probably do is 250 at turn on.

Haven’t kept up with 26650 batterries. The last I know of that delivered the highest output was the Shockli.
Any other recommendations ?
Efest is good also.

I believe the aspire 4300 is the lowest internal resistance 26650 now. This cell is the same as the golisi 4300 which HKJ tested.
