Matter Smart Bulbs, ST19/ST58 E26 Led Bulb Compatible with Alexa, Smart Light Bulbs, WiFi Bulbs, RGBTW Color Changing

Key Features

• NOTE: Before you buy, please confirm fit: this is a ST19/ST58 E26 smart light bulb sized 2.28 in / 58 mm (diameter) × 5.04 in / 128 mm (height), ideal for pendant lights, table lamps, floor lamps, and open vintage-style fixtures where the bulb is visible. It supports 2.4GHz Wi-Fi only (not 5GHz). This bulb is not compatible with wall dimmer switches (may cause flickering/buzzing), so adjust brightness via the /Matter app or voice control and use a standard on/off switch
• Spiral Filament Look: This ST19 Edison-style smart bulb features a visible 3D spiral LED filament, creating a decorative "floating ribbon" look even before you turn it on. The vintage glass shape is perfect for exposed sockets, pendant lights, cafés/bars, and clear glass shades, giving your lighting a premium, decor-forward feel while you switch colors, tunable whites, and scenes in the app or by voice
• 16M Colors & Tunable White: This color changing smart bulb offers 16 million colors plus tunable white 1800K-6500K (RGBTW), so you can go from cozy warm ambience for relaxing to crisp cool whites for reading or work. It combines RGB and tunable white in one E26 Wi-Fi bulb, making it easy to set the right atmosphere for movie nights, parties, dinner time, or bedtime with a tap or simple voice command
• Powerful Smart Matter: This Matter smart bulb works with major Matter platforms like Alexa, so you can add it to the smart home system you already use and keep control consistent across devices. Matter support helps reduce app switching and simplifies multi-brand setups, giving you a smoother smart home experience and a more dependable way to manage smart lighting at home
• Smart Schedules & Routines: Timers, schedules, and sunrise/sunset automation help lighting match your daily rhythm, so you can wake up gently, relax in the evening, and turn lights off automatically without manual switching. This is ideal for bedrooms, living rooms, and entryways, meaning your app-controlled smart bulb supports comfort and energy saving in the background
• Group & Remote Control: Group multiple E26 smart bulbs in the app and control them together, so you can turn on/off, dim brightness, or change colors across a whole room at once (e.g., "Living Room," "Dining Area," or "Bedroom Lamps"). Remote control from anywhere helps you keep lighting consistent and coordinated when you're away
