Q: The device is labelled 9V 1A, but the description says 500mA - what is the correct value?

Griddlockk Generally, LEDs require between 20mA to 350mA. From the specs I have read on similar products, I would use these with 300mA. This is a 1-Watt bulb. Watts = Volts x Amps. So, if you were to supply 333mA at 3V, you would get your 1 Watt of power. I don't know if these have internal resistors, so assuming that they don't, you will need to add one into your circuit. Remember, LEDs are merely diodes that give off light, and they have very little resistance on their own. The proper resistor value is calculated with the formula R = (V / I), resistance equals volts divided by amps. R = (3V / 333mA) = 9 Ohms So a 10 Ohm resistor will for sure keep the LED safe at 3V. For the sake of argument, lets say you wanted to run this LED at 12V and only 250 milliAmps... R = (12V / 0.250A) = 48 Ohms.

Kisdobos Myguitar effect works only with 9V 1A, so I can say it IS 9V 1A . It works well.
