Flood Beam
noun
Definition of Flood Beam
A flood beam is a wide, evenly distributed beam of light designed to illuminate large areas with consistent brightness.
In marine applications, flood beams are used for navigation, docking, fishing, and other activities where broad, shadow-free visibility is critical.
Unlike spotlights that focus light into a narrow beam, floodlights are engineered to spread light over a wide angle, typically 45° to 120°, providing even coverage and excellent peripheral vision without glare.
Flood beam lights are popular as spreader lights, deck lights, and dock lights, helping illuminate bait rigging, anchoring, and night operations on both fishing and recreational vessels.
Typical Uses
-
Fishing: Bright, glare-free illumination for rigging and deck work.
-
Docking: Improved visibility when approaching or leaving the marina.
-
Deck Lighting: Wide, even coverage for passengers or work areas.
-
Navigation: Enhances safety and visibility during night operations.

Frequently Asked Questions
What’s the beam angle for flood lights?
Flood beams typically range from 45° to 120°, offering broad, even light coverage across the deck or dock.
Are flood beam lights waterproof?
Yes. Most marine-rated flood lights are IP67-certified, meaning they can handle heavy spray, rain, and submersion.
Can I use them for fishing?
Absolutely. Flood beams provide bright, wide light that’s ideal for bait rigging, cleaning, or fighting fish at night.
Do they work on 12V systems?
Yes. Most models are compatible with 12V or 24V DC systems, making them plug-and-play for boats of all sizes.
How do flood beams differ from spot beams?
Floods light up wide areas, while spot beams focus on long-distance, narrow illumination for targeting or navigation.
