Cool White 28mm SMF2 LED Bulb Pair Diode Dynamics

The 28mm SMF2 LED bulb serves as a direct replacement for any bulb of 28mm size commonly found in vanity mirror lights in many vehicles.

Populated with two 5050-size SMDs, the SMF2 upgrades the factory yellowish incandescent bulb to a more modern LED appearance while adding significantly more total light output than the factory bulb.

Designed with an embedded load resistor and implanted diode, the SMF2 ensures superior reliability.

With durable metal terminals, it fits snugly in the socket, and its lightweight design prevents it from vibrating 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.

With 16 lumens of true measured output, the SMF2 LED provides about double the total light compared to the original 28mm-sized bulb.

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 the real numbers for comparison.

In addition to vibrant colors of blue, red, amber, and green, the SMF2 is available in cool white 6000K and warm white 3000K options.

Whether you want a modern cool white appearance or a traditional warm white color, we have the color to fit your need.
