1. A lamp control system comprising:

  • a plurality of parallel lamp modules, each parallel lamp module comprising control electronics configured to selectively couple a DC power source with a load to selectively drive the load;

    a separate control circuit for each parallel lamp module, each control circuit being configurable to send a same control command to the control electronics of each of the parallel lamp modules at the same time so that each of the control electronics is configured to selectively drive the load identically; and

    at least one relay configured to selectively couple one of the parallel lamp modules with the load and decouple each of the remaining parallel lamp modules from the load so that the control electronics of the one parallel lamp module selectively drive the load according to the control command.
