Using my DMM and the diode selector, the SMDs 3528 in a brand new Led bulb does not light. I used this method to test the classic "round" leds but in this case it does not work. What seems to be wrong here?
The forward voltage of the LED might be higher than the test voltage of the multimeter, usualy red LEDs have the lower forward voltage and blue and white ones have the higher voltage.
