Underwater Light Having Programmable Controller and Replaceable Light-Emitting Diode (LED) Assembly

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 communicating LED drive signals between the LED driver subsystem and the plurality of LED strings.
