Smart bulbs are the quick and easy way to bring wirelessly controlled lighting to your home, even if you live in an older house, condo, or apartment. They require constant power and a steady Wi-Fi connection, and flipping the physical switch that controls your light socket temporarily breaks the setup. That's why smart home builders often turn to smart switches instead. Smart switches connect to your smart home through the wiring in your wall, and work with any type of bulb — including incandescent, LED, or halogen bulbs.
