The Sonoff B02-F-ST64 is a smart LED filament bulb that blends a classic Edison aesthetic with modern connectivity. Designed for E27 bases, it provides 700 lm of brightness at 7W and features an amber glass finish in the vintage ST64 shape, making it a subtle addition to lamps or pendant lights where visual style matters. You can adjust the color temperature from a warm 1800K to a crisp 5000K via the eWeLink app on Android or iOS, allowing you to shift the mood of a room from cozy to focused. The bulb connects over 2.4 GHz Wi-Fi and supports voice commands through Amazon Alexa, Google Assistant, and SmartThings, so you can dim the lights or trigger one of the four preset modes without reaching for a switch. Built with durable LED filaments and glass, this 220V bulb is rated for up to 15,000 hours of use. It is well-suited for those who want to automate their home lighting through scheduling or group control while maintaining the timeless look of traditional filament lamps.
