   • Used for channel observation, deck operation and rescue
   • High power, long irradiation distance, waterproof and wave-resistant
3. Accommodation & Cabin Lights
   • Applied in living quarters, wheelhouse, engine room, corridors and toilets
   • Focus on soft lighting, fireproof, damp-proof properties
4. Deck & Outdoor Lights
   • Installed on decks, bulkheads and flybridges
   • Require high protection: IP66/IP67, salt-fog resistant and UV resistant
5. Emergency Lights
   • Automatically turn on when main power fails
   • Used in escape routes, engine rooms and wheelhouses, complying with marine safety regulations
6. Local Working Lights
   • Inspection lights for engine rooms, kitchen working lights and reading lights
   • Adjustable angle, oil-proof and damp-proof
7. Decorative & Ambient Lights
   • Exclusive for yachts: RGB light strips, underwater lights, railing lights and ambient spotlights

4. Underwater Lights: IP68, suitable for long-term immersion

IV. Classification by Light Source Type

• Incandescent lamps (gradually phased out)
• Halogen lamps
• LED lamps (mainstream at present)
  • Energy-saving, compatible with low voltage, long service life and vibration-resistant
• Fluorescent lamps (mostly used in engine rooms and cargo holds)

V. Classification by Supply Voltage

• Low-voltage DC: DC 12V, 24V (mainstream for yachts and small vessels)
• AC: AC 220V, 110V (large vessels)
• Emergency power supply: Powered by 24V emergency batteries

VI. Classification by Vessel Type (Yacht-specific)

1. Luxury Yacht Lights: Intelligent dimming, RGB ambient lighting, stylish design
2. Work Boats / Fishing Boats Lights: Durable, high brightness, high waterproof performance
3. Sailing Boat Lights: Low-profile installation, wind-resistant and power-saving
