Sengled smart Wi-Fi LED 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 2.4 GHz Wi-Fi network. Control the bulb through the Singled home app to manage your lights, including adjusting the brightness, setting schedules, creating scenes and monitoring energy. You can also control the light with your voice when paired to your Amazon Alexa device.
