Placement decides whether a dock looks designed or decorated.
Even spacing along the outboard face, one fixture per lift cradle, a light at the dock's terminal end, and nothing aimed where it will glare into the living space.
On seawalls we space wider and let the halos overlap softly for a continuous ribbon of light.

How much electricity do underwater lights use?
Far less than people assume — a typical dock runs for pocket change per month.
Can underwater lights stay on overnight?
They can, and they should. Marine-grade LEDs are built for continuous immersion.
How deep should underwater lights be?
Usually 12–24 inches below the mean low water line. Depth controls the halo.
Christopher will confirm these numbers on site and refine the plan to your dock.
