28mm SMF2 LED Features
- Direct replacement for factory 28mm festoon bulb
- Increased output with LED appearance
- Plug and play, simple installation
Design. The 28mm SMF2 LED bulb is a direct replacement for any 28mm-size bulb, 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 far more total light output than the factory bulb. The SMF2 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 16 lumens of true, measured output, the SMF2 LED will provide about double the total light compared to your 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 you the real numbers to compare.
