1. An underwater light, comprising:
a controller printed circuit board assembly (PCBA), including:
a microcontroller subsystem including a microcontroller,
a light-emitting diode (LED) driver subsystem in communication with the microcontroller subsystem, the LED driver subsystem receiving pulse-width modulated (PWM) signals from the microcontroller subsystem and being controlled by the PWM signals, and
a power subsystem providing power to the microcontroller subsystem and the LED driver subsystem;
an LED printed circuit board assembly (PCBA) in communication with the controller PCBA, the LED PCBA including a plurality of LED strings in communication with and driven by the LED driver subsystem; and
a connector connecting the controller PCBA to the LED PCBA, the connector establishing bidirectional communication between the controller PCBA and the LED PCBA and communicating LED drive signals between the LED driver subsystem and the plurality of LED strings.
