Single 39mm SMF2 LED Bulb Warm White Diode Dynamics

The 39mm SMF2 LED bulb serves as a direct replacement for any bulb of 39mm size, commonly found in dome lights, trunk lights, and door 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 ensures longevity, lasting for years without flickering or failure.

Like every Diode Dynamics product, it comes with an industry-leading three-year replacement warranty.

With a true, measured output of 39 lumens, the SMF2 LED provides slightly more light than your original 39mm-sized bulb.

For increased 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 real numbers for comparison.

The SMF2 is available in vibrant colors including blue, red, green, and amber, as well as cool white 6000K and warm white 3000K options.

Whether you prefer a modern cool white appearance or a traditional warm white color, we have the right option for your needs.

Diode Dynamics has been a trusted name in automotive LED lighting for over a decade.

Unlike other LED distributors, we manufacture and engineer our products in the United States, ensuring high quality and a fast time-to-market for the latest and brightest LED technologies.

We focus on offering quality LED products that meet your expectations.
