The Diode Dynamics 28mm SMF2 LED bulb in blue is a direct replacement for 28mm festoon bulbs commonly used in vanity mirror lights, upgrading yellowish incandescent lamps to a modern LED appearance while providing about double the light of the original bulb. Populated with two 5050 SMDs and rated at 24 lumens, the SMF2 includes an embedded load resistor and implanted diode plus constant-current circuitry and transient suppression. Durable metal terminals ensure a snug fit and plug-and-play installation, and the bulb is backed by a three-year replacement warranty.
