LED 120Vac

Simple, very low consumption and safe circuit to supply a LED with 120Vac. Due to the capacitive reactance behavior, changing the capacitance of C1 will change the current supplied to LED in a direct proportion: the higher is the capacitance, the higher will be the current to LED, and vice-versa. Thus it's possible to use different type of LED as well as other values of input AC voltage just adjusting the C1 capacitance value.
