Abstract

Systems and methods are provided for lighting systems, including high output lighting systems for various environments. The lighting systems include a lighting controller for driving lighting modules and transmitting a data signal to the lighting modules. The data signal varies between logical states. The lighting controller provides a low loss rectified power signal. The lighting controller further provides data within the power signal by forming a positive polarity rectified power waveform corresponding to data in a first state and a negative polarity rectified waveform signal corresponding to data in a second state using substantially loss-less circuitry.
