Collection: Bulbs

Replacing a bulb on a boat involves more variables than a typical home swap. Base type matters first: options here cover BA15S single-contact, BA15D double-contact, G4 pin, E26 screw, and festoon sizes including 31mm and 42mm, and fitting the wrong base simply will not work. Lunasea Lighting makes up the bulk of this selection with LED alternatives across all those bases, while Jabsco covers sealed beam replacements for searchlights and Golight supplies halogen bulbs alongside matching lenses and reflectors for their spotlight systems. Voltage range is the next check, as marine systems vary and Lunasea's silicone encapsulated LED bulbs are rated for 10-30VDC, making them compatible across 12V and 24V setups.

Color temperature is a practical choice, not just an aesthetic one. Cool white delivers higher apparent brightness useful for task and navigation lighting, while warm white reduces glare and suits cabin and cockpit spaces. Lunasea also offers a red festoon option suited to preserving night vision. LED bulbs across this range deliver meaningful lumen output well above equivalent halogens and draw less current, which matters on an anchored boat running off battery. Silicone encapsulation on many Lunasea models adds resistance to condensation and spray.
