Description

The Diode Dynamics 31mm SMF2 LED bulb is engineered as a direct replacement for factory 31mm festoon bulbs, commonly found in vanity mirror lights. This bulb upgrades the original yellowish incandescent light to a modern cool white LED appearance, significantly enhancing both aesthetics and illumination. Each SMF2 bulb is populated with two 5050-size SMDs and outputs 24 lumens of true, measured light, approximately doubling the output of a standard 31mm bulb. The design incorporates constant-current circuitry and transient suppression for superior reliability and longevity, preventing flickering or premature failure. Its durable metal terminals ensure a snug and secure fit within the socket, minimizing vibration-related issues. Diode Dynamics backs this product with an industry-leading three-year replacement warranty, underscoring its commitment to quality and customer satisfaction.
