It depends on the PSUs - if one has a floating output; you're in the clear.Hi,

I am very new, Planing to to have step down with a knob to limit voltage and using 2 CPU heatsinks and fanHow will you limit its current and cool the LED? Please post its datasheet.
SorryHave you bought the parts yet?
Try to spell out exactly what you need in the end.
And I’m confused, you state 3 different voltages for the higher supply.
