Can anyone identify these HD12 LEDs?
Me Opple LM4 says those are CRI75 LEDs, but I don’t put my trust in this device… Tint seems legit though - reads 4662K in low mode with DUV 0.0118

The photo on the page shows different corner marks, but check out the photo in the datasheet.

Looks like the main LEDs are connected in series, so they are powered by a boost driver indeed.
Also I wonder how one can extract that mcpcb? Where are the wires?
That’s interesting, I was sure they would just use CSP LEDs on this light, just like in the TS10 and HD10 but somehow they opted for 3535 LEDs. Can you send pictures of the TIR optics?
Would anybody owning this headlamp care to comment on how it feels in practical use?

I have very mixed feelings: https://www.reddit.com/r/flashlight/s/xX5nz3HgLD
BTW: later application of the d-x-fix foil did not help much.

Mine is around neutral and seems high CRI, as other measurements confirmed. The beam is a bit narrow, but surprisingly that didn’t bother me in real use, just the first view was a bit… odd. The UI is very good for me, the headband is comfy and light, but for harder use i wouldn’t trust the oring too much. On the other hand, the oring is placed so that it is protected quite good. Sustain is a bit higher than that of my hd10, for a light that size more than enough. The red is surprisingly very good.
I bought it more out of curiosity and because it was cheap, but it has become my most used headlamp since i have it. Mostly because its light, simple, good brightness, a good amount of reach and the brightness is enough for most tasks. But i didn’t expect too much from it, so maybe thats the reason i am so positive about it.
