{"title":"Smart bulb","description":"\u003cp\u003eA smart bulb screws into a standard socket, turns on at the wall like any other bulb, then is adjusted from a phone: brightness, hue, schedules. The choice comes down to three concrete points: the fixture's socket, the control method (Bluetooth or Wi-Fi) and the colour temperature suited to the room.\u003c\/p\u003e\n\n\u003ch2 id=\"quest-ce-quune-ampoule-connectee\"\u003eWhat is a smart bulb and what is it for?\u003c\/h2\u003e\n\u003cp\u003eA smart bulb is an LED bulb controlled from a mobile app or by voice, with no extra switch. You adjust brightness, sometimes colour, and schedule timings. It screws into a standard E27 or E14 socket, or fits a GU10 spot, like a classic bulb. Remote and voice control runs through Alexa or Google Assistant; exact compatibility should be checked on each product page.\u003c\/p\u003e\n\n\u003ch3\u003eSmart bulb: uses room by room\u003c\/h3\u003e\n\u003cp\u003eIn a bedroom, it takes over the bedside lamp's role: warm white for reading, very low brightness for lights out, without getting up. Proximity control is enough in a single room and avoids depending on the network. In a living room, the same model follows the day, neutral for working, warm in the evening.
