The 28mm SMF1 LED bulb serves as a direct replacement for any bulb of 28mm size, 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.
Its durable metal terminals allow for a snug fit in the socket, and its lightweight construction means it won't vibrate loose over time.
Unlike other bulbs on the market, this bulb features constant-current circuitry along with transient suppression.
This design allows the bulb to last for years, not months, without flickering or failure.
Like every Diode Dynamics product, it is backed by an industry-leading three-year replacement warranty.
With 8 lumens of true, measured output, the SMF1 LED provides similar light output to your original 28mm-sized bulb.
If you wish to increase output, consider checking out our SMF2 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 for comparison.
In addition to vibrant colors such as blue, red, amber, and green, the SMF1 is also available in a cool white 6000K and warm white 3000K option.
Whether you prefer a modern cool white appearance or a traditional warm white color, we have the color to fit your need!
