From searching around, I've read LM301z, LM301b, and Osram. Not sure what the truth is, but those are fine diodes. The LM301z is a lesser binned, or cheaper made LM301b?
The driver is listed as "Sosen." Don't know anything about Sosen drivers.
I'm sure it's a good light, but not as proven as the Mammoth components maybe.
The Mammoth is using latest/greatest LM301b/h, and Inventronics driver (my HLG 350r uses an Inventronics driver too fwiw)
The Mammoth would be my pick, but either way is gonna grow some quality dope.
