The 28mm SMF1 LED bulb serves as a direct replacement for any 28mm-size bulb, commonly found in vanity mirror lights in many vehicles.
Populated with one 5050-size SMD, the SMF1 upgrades the factory yellowish incandescent bulb to a more modern LED appearance.
Designed with an embedded load resistor and implanted diode, the SMF1 ensures superior reliability.
With durable metal terminals, it fits snugly in the socket, and its lightweight construction means it won't vibrate loose over time.
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.
With 8 lumens of true, measured output, the SMF1 LED provides similar light output to your original 28mm-sized bulb.
In addition to vibrant colors of blue, red, amber, and green, the SMF1 is available in a cool white 6000K and warm white 3000K option as well.
