Power Supply VS 50 Watt Chinese LED.

I Dial in 27v, but limit the current to 0.02amps (CC/CV)

0.54watts of energy being supplied to the diodes, now the voltage it reads AFTER connecting the LED varies on the wavelength of the LED and band gap or something or other, but just what is precicly going
on here... with the voltage...

how come we don't see 27v at 0.02amps from every row?

This is correct. The higher the frequency (shorter the wavelength) of the light emitted by an LED, the higher the voltage required.

That was AWESOME amount of light being emitted at 1A. WOW!

Y'know I never noticed that correlation before you mentioned it. :astonished:
