Warm white double contact bayonet base LED bulb

Product Description

Upgrade your lighting with our Double Contact Bayonet LED Bulb, featuring 18 warm white SMD LEDs engineered for uniform illumination in dome lights, reading lamps, chart lights, and more. This low-power LED retrofit is perfect for interior use aboard boats, RVs, campers, or vehicles.

Operating on 10–30 V DC, each bulb is equipped with a built-in filter to eliminate electromagnetic interference (EMI) and voltage regulation to guard against spikes—ensuring smooth, flicker‑free light in any environment.

With a slim 2.5 W power draw, this bulb remains cool‑running, extending the service life of light fixtures and preserving onboard battery power. The double contact bayonet base (9/16″ × 3/4″) ensures secure, drop‑in compatibility in fixtures with two bottom electrical contacts and side‑plane pins. At just 7/8″ in diameter and ~1‑3/8″ long, it’s compact enough for tight dome or reading light housings.

This energy‑efficient LED bayonet bulb delivers soft, warm white illumination—ideal for cozy interior lighting—while running cooler, consuming less power, and eliminating glare or hotspot issues found in other LED bulbs. Marine boaters and RV enthusiasts can confidently replace older incandescent bulbs to reduce strain on electrical systems and improve onboard lighting quality.
