Abstract
Methods to identify a fluorescent lamp among multiple fluorescent lamps include: receiving input to a circuit including multiple fluorescent lamps operated by corresponding multiple control signals, each fluorescent lamp configured to output radio frequency (RF) signals in response to receiving a detection signal, the input to identify which first control signal is provided to a first fluorescent lamp; in response to receiving the input, providing a first discovery signal in place of each control signal provided to each fluorescent lamp, one fluorescent lamp at a time; determining that the first fluorescent lamp outputs RF signals; and identifying the control signal that was replaced with the detection signal that caused the first fluorescent lamp to output the RF signals.
