Drop-In LED Upgrades for the Most Common Marine Bulb Bases
These Scandvik LED replacement bulbs are designed to swap directly into fixtures using G4, Bayonet, or Festoon base types — the three most common bulb formats found in marine cabin lights, reading lights, and interior fixtures. Built on high-output SMD 5050 LED technology, they deliver similar or brighter output than the halogen or incandescent bulbs they replace, while drawing 60%+ less power.
Multi-voltage rated at 10–30 VDC, these bulbs work on both 12V and 24V systems without any modification. They run cool to the touch, which reduces heat buildup in enclosed fixtures and improves safety in confined cabin spaces.
Key Features
- Fits G4, Bayonet, and Festoon base types
- High-output SMD 5050 LEDs — equal or brighter than halogen/incandescent equivalents
- 60%+ more efficient — significantly lower amp draw
- Multi-voltage: 10–30 VDC (12V and 24V compatible)
- Low operating temperature — cool to the touch
- Sold in clamshell packaging
Best Use Cases
- Upgrading halogen or incandescent bulbs in marine cabin lights, reading lights, and interior fixtures
- Reducing electrical load on 12V or 24V marine systems
- Replacing failed bulbs in G4, Bayonet, or Festoon-base fixtures without changing the fixture
