Zemismart Filament Light Bulb E27

This bulb blends a vintage filament look with modern Matter-enabled smart control, giving you flexible lighting that works smoothly across multiple smart home systems.

The ST64 bulb combines a classic warm-glow filament style with full smart functionality. Because it’s Matter-certified over Wi-Fi, it can plug into nearly any smart home ecosystem—SmartThings, Siri, Alexa, Google Home—without relying on brand-specific hubs. Its adjustable brightness and wide white-temperature range let you shift from soft amber light to a clearer, cooler tone depending on the room or time of day. The design is aimed at people who want the charm of an exposed filament bulb but with the convenience of app and voice control for everyday lighting changes.
