Re: Lamp Current vs Voltage
O.k., well, given that it's so cheap to make it, is it possible to design a circuit with redundancy, such that if one component fails, then another one takes its place? Or even just three complete units, with some sort of a sensor which would 'decide' which one to feed electricity to, and which to d...
