Nautical deep-sea lights are essential devices for navigation at night or in low-visibility conditions. Typically installed on the bow, roll-bar, or deck of boats and yachts, these lights illuminate large areas of the sea in front of the vessel or near the seabed, also useful for docking, fishing, or emergencies.

🔦 Types of nautical deep-sea lights

1. Narrow beam LED headlights Illuminate far, cool light, low consumption -> Quick navigation and search
2. Wide beam LED lights Illuminate close and wide areas -> Maneuvers, fishing, seabed
3. Submersible/underwater lights Installed under the transom -> Night fishing, visibility of the seabed
4. Halogen or Xenon headlights (old generation) High power, but high consumption -> Older ships or outdated systems
5. Adjustable/remote spotlights (spotlights) Electronically adjustable -> For megayachts, patrol boats, SAR

✅ Features to evaluate

• Luminous power : expressed in lumens (e.g. 2,000–20,000+ lm)
• Beam angle : narrow for long distance, wide for close area
• Waterproof : IP67–IP69K (resistant to immersion and water jets)
• Materials : anodized aluminum, 316 stainless steel or marine ABS
• Voltage : 12V or 24V, compatible with marine systems
• Mounting bracket : adjustable, with anti-vibration protections

🔧 Practical uses on board

• Night navigation in inland or poorly marked waters
• Sighting of floating obstacles or buoys
• Anchoring in the roadstead or night-time maneuvers in port
• Night fishing (fish lure or bottom lighting)
• Inspection and recovery of objects at sea
