Is this LED light in series or parallel or both?

Is it a mix of both?
I think I've noted 13 series circuits here, all feeding from the one big positive pad (see green overlay).
If this is the case, how does the power get equally distributed to each of the 13 series circuits? Please be kind I have a limited idea of electronics.
I believe this light uses a constant current driver, but don't have specs at the time.

They use ground planes and power planes on most LED boards in a series/parallel. You won't find many small traces. The power gets distributed very close to even because of similar resistance/threshold voltages of the series.
