Abstract
According to one aspect, a control circuit for a tubular light emitting diode (TLED) lamp may include an input detection circuit that detects, from an input signal, a type of control desired based on a characteristic of the input signal and generate an output signal, a digital control circuit that controls operation according to a digital lighting protocol, and an analog control circuit that controls operation according to a voltage associated with the input signal. The digital control circuit may be enabled or disabled based on the output signal. The analog control circuit may be enabled or disabled based on the output signal.
