hmmm, i expect better number from that led, maybe 5000lumen and 250kcd

The reason should be the diameter :wink:

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

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

:open_mouth:

Can I ask, what driver you are using? Does it has his own driver specific design for ? I mean booster?or buck?

Interested!

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…

What battery is it gonna use?

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.
