As an experiment, and for my own education into electronics I am trying to light up one LED diode in my 60wLED bulb. I have pulled the bulb apart, I have tested the bulb, and it still illuminates. Now, I am trying to test each of the 8 LED's. I have applied a variable 6-12V power source to the LED, yet it still won't illuminate. Can anyone suggest what I might be doing wrong?
I can confirm that the power source is putting out the correct voltage 7.5V and or 9V, because I checked it with a multimeter.
