Warm White Back Pin G4 Halogen LED Replacement

Product Description

Upgrade your boat’s reading lights or other fixtures with our 2-Pin Halogen LED Replacement Bulb, designed to fit G4 installations where the bulb is inserted from behind (back pin). This bulb features a slightly larger disk than the LG4B12WW-25, allowing it to house 21 warm white (3200K) SMD LEDs that deliver a bright 270 lumens — the equivalent of a 17W halogen bulb but without the excess heat and energy consumption.

The extra-long 1-inch pins make it easy to install inside many shades commonly found on marine reading lights. For custom fits, the pins can be trimmed without affecting performance or safety. With an outer diameter of 1.38", this LED bulb provides excellent light coverage in a compact design.

Engineered for durability, it operates on a wide 10–30V DC range and includes an EMI filter plus voltage regulation to protect your sensitive electronics from interference and voltage spikes, ensuring safe and reliable operation on your vessel.

Backed by a 2-year warranty, this LED halogen replacement bulb is the perfect upgrade to brighten your boat’s interior lighting with energy-efficient, long-lasting warm white light.
