The 31mm SMF2 LED bulb serves as a direct replacement for any bulb of 31mm size, commonly found in dome lights, map lights, and trunk lights in various vehicles.
Populated with two 5050-size SMDs, the SMF2 upgrades the factory yellowish incandescent bulb to a more modern LED appearance.
Designed with an embedded load resistor and implanted diode, the SMF2 ensures superior reliability.
Its durable metal terminals allow for a snug fit in the socket, and its lightweight construction prevents it from vibrating loose over time.
Unlike other bulbs available, this bulb features constant-current circuitry along with transient suppression.
This design means the bulb will 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 19 lumens of true, measured output, the SMF2 LED provides similar light output to your original 31mm-sized bulb.
If you wish to increase output, consider our HP6 option!
All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or estimates.
We test the true output in-house and provide you with the real numbers for comparison.
In addition to vibrant colors such as blue, red, amber, and green, the SMF2 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 meet your needs.
