12V and 24V Submersible LED Fishing Lights

Comlite’s 12V/24V range covers 20W to 800W underwater fishing lights that run straight off a boat battery or a portable pack — no generator, no mains connection. Models include self-sinking portable units for kayaks and small boats, dimmable lights with protective cages for inshore work, and high-power 400W-800W units for commercial boats.

The number that decides everything on a battery system is runtime. Divide the wattage by the system voltage to get the current draw: a 20W light on 12V pulls about 1.7A, so a 100Ah battery runs it for roughly 48 heures. The same battery runs a 120W light for about 8 hours and a 450W light for just over 2 heures. Choose the wattage for the species and water, then size the battery for how long you plan to fish.

Choosing a 12V/24V Fishing Light

• Match the system. Most small boats and kayaks are 12V; larger vessels run 24V. Several models in this range accept both.
• Size the output to the water. 20-60W for kayaks, canoes and small ponds; 200-450W for inshore boats; 600-800W for commercial boats working deep water.
• Pick the colour for the water. Vert (520-560 nm) travels farthest in coastal and estuary water; le bleu convient aux eaux claires au large; white is best for loading and working light.
• Check the cable and the cage. Commercial boats and rocky ground need a protective cage and a cable long enough for the drop you plan to work.

If you have mains power at a dock, pond or fish farm, see our 220V AC underwater fishing lights, ou onboard and dock lights for fixed installations. Request a quote with your boat voltage, target species and working depth.
