I recently harvested 5 bright white COB LEDs from a light fixture and am trying to figure out what kind of power it would take to power them individually.
The fixture contained a transformer with an output of 36VDC 0.47A Max and was epoxy potted so I can't see if there were any resistors inside.
The LEDs were simply wired in series, so ignoring any resistors, can I assume that the voltage drop across each LED is somewhere around 7.2V? I tried measuring the Vf of an individual LED on my meter but couldn't get a reading. (36/5=7.2) If not, is there any way to calculate/estimate what it would take to power these LEDs individually?
