Dock Lighting Sizer & Quote Builder
Configure each dock lighting run, then add it to your quote. We’ll size tinned copper marine-grade wire and a DC power supply using an evenly distributed-load approximation and your allowed voltage drop.

Tip: Pick a model to auto-fill watts. You can still fine-tune the watts per light for your exact product.

Tinned Copper Marine-Grade Wire
Best option for longevity. Resists corrosion far better than bare copper. Flexible for vibration and movement around docks. Meets ABYC standards.
