Lunasea Single-Sided 4 LED Festoon - 10-30VDC/0.7W/60 Lumens - Warm White

The Lunasea Single-Sided 4 LED Festoon is a high-efficiency low-voltage lighting solution designed for marine, RV, and tactical vehicle applications where space is limited and reliable long-term performance is non-negotiable. Built with a precision internal buck regulator, this 60-lumen festoon bulb maintains stable output across the full 10–30VDC input range, making it ideally suited for systems with variable charging conditions common in field deployments and offshore environments.

Rated at 0.7W with a warm white color temperature, the LLB-202W-21-00 delivers efficient illumination across a 120-degree viewing angle in a compact 31mm form factor. The integrated buck regulator eliminates the need for external voltage regulation, reducing wiring complexity and failure points—a critical design choice for vehicles operating in harsh conditions. Extended service life of up to 50,000 hours minimizes replacement cycles during extended operations, reducing logistics burden and downtime. The single-sided LED configuration and narrow profile make this bulb compatible with standard festoon-style fixtures found in cabin lights, instrument panel lighting, and utility compartment installations.

This festoon bulb serves operators, maritime professionals, and vehicle specialists who require dependable cabin or instrument lighting in 12V or 24V systems. Its warm white output preserves night vision adaptation better than cool white alternatives, a consideration for tactical and nocturnal applications. The low power draw (0.7W) makes it suitable for battery-critical installations where parasitic drain must be minimized. Replacement is straightforward in existing fixtures, requiring no rewiring or additional hardware.

Lunasea Lighting has established itself as a producer of marine-grade LED lighting components, and the festoon series reflects that focus on voltage stability and environmental durability. For buyers upgrading aging incandescent or halogen cabin lights to efficient LED solutions, the internal regulator and extended lifespan represent meaningful operational advantages over unregulated aftermarket festoon bulbs.
