Smart bulbs are energy-efficient light bulbs that can be controlled remotely using a smartphone, tablet, or smart home device. They connect to your home Wi-Fi network, allowing you to adjust brightness, color, and even set schedules for when the lights turn on or off. These bulbs often work with voice assistants like Amazon Alexa or Google Assistant, enabling hands-free control. Many smart bulbs also offer features like color-changing options and energy usage tracking, making them a popular choice for modern homes looking to enhance convenience and efficiency.
