An LED is now a power emitter. Things just keep getin' curioser and curiouser. This is without a doubt like the deaf and the blind trying to communicate; I can't interpret ASL (American Sign Language) and you can't hear me screaming. Why does an LED, used to incicate that the power is on, require several hundred milliamps and a switching regulator? This great long thread has completely failed to articulate a coherent answer, or even explain the purpose of such a device.
