A smart bulb is an energy-efficient light bulb that can be controlled remotely using a smartphone, tablet, or smart home device. These bulbs often connect to your home Wi-Fi network, allowing you to adjust brightness, color, and scheduling from anywhere. Many smart bulbs are compatible with voice assistants like Amazon Alexa or Google Assistant, enabling hands-free control. They can also be integrated into home automation systems, allowing them to work in sync with other devices, such as smart thermostats or security cameras, enhancing convenience and energy management in your home.
