Can underwater lights stay on overnight?
They can, and they should. Marine-grade LEDs are built for continuous immersion.
Designed for duty cycles
Our fixtures are potted, sealed and heat-sinked to the water itself, so running dusk to dawn is well inside spec. Water is the best cooling system a light can have.
Why consistency helps
Fish learn schedules. A light that runs the same hours every night produces better fishing than one used occasionally.
