From Sengled: Smart Lighting Expert. Lighting up the world since 1997 Sengled WiFi Classic Smart Light Bulbs are the simplest way to get started with smart lighting. No hub is required — just install the LED bulb like a standard light bulb and connect it to your home's 2.4GHz Wi-Fi network. Control the bulb through the Sengled Home app (iOS and Android) to manage the smart lights, including adjusting the brightness, setting schedules, creating scenes and monitoring energy. You can also control the lights with your voice when paired to your Google Assistant smart speakers.
