Smart bulbs are energy-efficient light bulbs that can be controlled remotely using a smartphone, tablet, or voice assistant. They connect to your home Wi-Fi network, allowing you to adjust brightness, color, and scheduling from anywhere. This technology helps save energy and can enhance home security by simulating occupancy when you're away. These bulbs often integrate with smart home systems like Amazon Alexa or Google Assistant, enabling voice commands for hands-free operation. Many smart bulbs also offer features like color-changing options and customizable lighting scenes, making it easy to create the perfect ambiance for any occasion.
