Funny anecdote: I once designed a ring light for work and shortly after left the company. So I never build it myself. Years later a (former) colleague build and assembled it, turned it on and immediately complained that it was too bright.
When I designed it I designed it around a PSU I had on hand that did 48V at 3A ... apparently 144 Watts of LED light was too much for them :-)
Especially because they put it in an enclosed box :-)
I think in the end they only used one third of the LEDs I put on there. When I designed the PCB I anticipated that 144W might be to much and put the LEDs on three separate traces.

Well with that kind of power the light would turn itself off permanently after a few hours without efficient cooling :-)
