Could someone tell me what the industry standard ring light is?

[Edith blazek]

If there is one that is. I'm guessing there isn't and most of the time when that quality of light is needed it's just constructed out of a couple of smaller lights like literibbons or asteras but I want to know if there's an industry equivalent of those ring lights mountable on the lens itself so if there is, let me know.

Kino used to make a ring light, the kamino, I think? It's been awhile but that was a popular little thing in the 90s.
