The 39mm SMF2 LED bulb serves as a direct replacement for any bulb of 39mm size, commonly found in dome lights, door 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 fit snugly in the socket, and its lightweight design prevents it from vibrating loose over time.
Unlike other bulbs available, 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 comes with an industry-leading three-year replacement warranty.
With a true, measured output of 39 lumens, the SMF2 LED provides slightly more light output than the original 39mm-sized bulb.
For increased output, consider the HP6 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 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 color to meet your needs.
After over a decade in business, Diode Dynamics has become the most trusted name in automotive LED lighting.
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 newest and brightest LED technologies.
We focus on offering only quality LED products that will meet your expectations.
