Typo, it’s Manker E02
Jerommel did the LED swap with his Manker E02 and the thermal pad was soldered directly to the copper slug. Manker uses hollowed PCB.

Sorry, I didn’t document the electroforming modification. It was when I joined CPF. I didn’t bother posting since some of my previous posts were banned there. Now looks like my country’s IP address also banned by CPF. The result was somewhat messy because I grew copper starting at the LED’s thermal pad. It looks like a sci-fi stuff - an LED on a pink copper coral.
As long as you can get the right copper plating solution it’s a fun project. I plan to make copper electroformed flowers with E21A “welded” in the center. Should make a very nice ornament.
This for example was made using real flower:
