The Kasa smart Wi-Fi light bulbs from TP-Link make it easy to upgrade ordinary lamps and fixtures. The range includes a multicolour bulb that can display a wide choice of colours and shades of white for ambience, entertainment and decor, and a dimmable bulb that lets users adjust brightness for reading, relaxing or working. Both connect directly to the home Wi-Fi network without a hub and can be controlled from a smartphone app or by voice through popular assistants. Schedules and timers allow lights to turn on and off automatically, which helps save energy and makes a home look occupied while owners are away. As LED bulbs, they offer efficient, long-lasting illumination.
