The Diode Dynamics 28mm SMF1 LED bulb set of four in cool white replaces 28mm festoon bulbs commonly used in vanity mirror lights, giving a modern LED look with light output comparable to the original incandescent. Each SMF1 uses one 5050 SMD and is rated at 16 lumens, and includes an embedded load resistor and implanted diode along with constant-current circuitry and transient suppression for long-term reliability. The molded construction and sturdy terminals ensure a secure fit, installation is plug-and-play, and the bulbs are covered by a three-year replacement warranty.
