Try a PM to the project owner?

I can't do that. I live outside of China and I can't register because it gives me the wrong phone number when registering, even though it's correct.
I don't have WeChat because I don't have a WeChat friend to help me register.

Try contact via their website on their profile page:

@triolatice   I'm pretty sure that's a 100W led COB with the LED substrate removed.

This one isn't the same as it has heatsinking but do a google for COB LED and you'll probably find the one you want
