39mm SMF4 LED Features

  • Increased output with LED appearance
  • Plug and play, simple installation

Overview

Design. The 39mm SMF4 LED bulb is a direct replacement for any 39mm-size bulb, commonly found in door lights, dome lights, and trunk lights in many vehicles. Populated with four 5050-size SMDs, the SMF4 upgrades the factory yellowish incandescent bulb to a more modern LED appearance, while adding more light output than the factory bulb. The SMF4 was designed with an embedded load resistor and implanted diode for superior reliability. With its durable metal terminals, it will fit snugly in the socket, and its light weight means it won't vibrate loose over time. 

Reliability. Unlike other bulbs on the market, this bulb is built with constant-current circuitry, along with transient suppression. That means this bulb will last for years, not months, with no flickering or failure. And like every Diode Dynamics product, it's backed by an industry-leading three-year replacement warranty.

Brightness. With 52 lumens of true, measured output, the SMF4 LED will provide double the amount of light output compared to your original 39mm-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 you the real numbers to compare.

Colors. The SMF4 is available in warm white 3000K, amber, and green. If you are looking for additional color options, we'd recommend checking out our HP6 option!

Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike every other LED distributor, we manufacture and engineer products ourselves in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations. Please contact us if you'd like to discuss your lighting project!
