Design. The 31mm SMF2 LED bulb is a direct replacement for any 31mm-size bulb, commonly found in map lights, dome lights, and trunk lights in many vehicles. Populated with two 5050-size SMDs, the SMF2 upgrades the factory yellowish incandescent bulb to a more modern LED appearance. The SMF2 was designed with an embedded load resistor and implanted diode for superior reliability. With its durable metal terminals, it will fit snugly in the socket, and its light weight means it won't vibrate loose over time.
Reliability. Unlike other bulbs on the market, this bulb is built with constant-current circuitry, along with transient suppression. That means this bulb will last for years, not months, with no flickering or failure. And like every Diode Dynamics product, it's backed by an industry-leading three-year replacement warranty.
Brightness. With 19 lumens of true, measured output, the SMF2 LED will provide similar light output to your original 31mm-sized bulb. If you are looking to increase output, we'd recommend checking out our HP6 option! All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare.
Colors. In addition to vibrant colors of blue, red, amber, and green, the SMF2 is available in a cool white 6000K and warm white 3000K option as well. Whether you want a modern cool white appearance, or a traditional warm white color, we have the color to fit your need!
Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike every other LED distributor, we assemble and engineer products ourselves in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations.
