It screws into a standard socket and is adjusted from a remote, an app or a voice assistant. Its use: mood, decor, visual signal, not the main lighting of a work room.\u003c\/p\u003e\n\n\u003ch3\u003eColour, saturation, intensity: the three settings of RGB light\u003c\/h3\u003e\n\u003cp\u003eThe hue chooses the colour (red, green, blue and their mixes), saturation sets its purity, intensity sets the power. A highly saturated colour at low intensity gives a clean halo behind a piece of furniture or on a wall; the same colour pushed to full tints the whole room and tires the eye. To dress a corner of a living room, a strong colour at low intensity is often enough, and \u003ca href=\"https:\/\/designix.fr\/collections\/ampoules-pour-salon\"\u003ebulbs designed for the living room\u003c\/a\u003e cover this use case. The result also depends on the fitting: an opaque shade concentrates light downwards, a glass diffuser spreads it. Before ordering, check the opening of your fitting in \u003ca href=\"\/collections\/luminaire\"\u003ethe Designix lighting catalogue\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhat an RGB bulb does not replace\u003c\/h3\u003e\n\u003cp\u003eA colour bulb cannot do the job of work lighting: reading, cooking or working on a screen needs a stable, even white. So keep a white light point in the room, ceiling light, desk lamp or wall light, and reserve colour for accents. A fixed colour for one evening also does not replace a warm-to-neutral white variation, which remains the right tool for going from dinner to tidying up.\u003c\/p\u003e\n\n\u003ch2 id=\"rgb-rgbw\"\u003eWhat is the difference between RGB and RGBW LEDs?\u003c\/h2\u003e\n\u003cp\u003eAn RGB bulb mixes three colours, red, green and blue, to produce reconstructed hues and whites. An RGBW bulb adds a dedicated white channel: whites are cleaner and colours stay crisp. RGBW suits better a room where you alternate coloured mood and everyday white light.\u003c\/p\u003e\n\n\u003ch3\u003eRGBW: white in addition to colours\u003c\/h3\u003e\n\u003cp\u003eOn a plain RGB bulb, white comes from mixing the three channels: it often leans blue or greenish, rarely towards a comfortable warm white. The dedicated white channel corrects this and lets you light normally without changing bulbs. Some models add a white adjustable in temperature, from warm around 2700 K to neutral around 3000 K: that is the most versatile formula for a living room. For a white result without colour, compare with \u003ca href=\"\/collections\/ampoules-coloris-blanc\"\u003ewhite-coloured bulbs\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eWhen RGB alone is enough\u003c\/h3\u003e\n\u003cp\u003eIf the bulb is only for mood, behind a piece of furniture, under a display cabinet or in a corner, the dedicated white channel is superfluous and complicates control.

For everyday lighting at home, a well-chosen \u003ca href=\"\/collections\/ampoules-led-1\"\u003eclassic LED bulb\u003c\/a\u003e in the right temperature stays simpler to use than a colour you will only switch on occasionally.\u003c\/p\u003e\n\n\u003ch2 id=\"pilotage\"\u003eConnected RGB bulb, remote or Bluetooth: how to control it?\u003c\/h2\u003e\n\u003cp\u003eThree families coexist: the remote supplied with the bulb, control by app over Wi-Fi or Bluetooth, and smart home protocols such as Zigbee, which require a compatible bridge. All let you choose colour, saturation and intensity; the difference lies in range, the number of bulbs controlled together and compatibility with voice assistants.\u003c\/p\u003e\n\n\u003ch3\u003eConnected RGB bulb: Wi-Fi, Zigbee or Bluetooth?\u003c\/h3\u003e\n\u003cp\u003eWi-Fi links the bulb to the home network: you control it from anywhere, and several bulbs can be grouped in the same scene. Bluetooth works without a hub, but only at close range and with a limited number of points. Zigbee requires a compatible bridge: it handles a large number of bulbs better and stays responsive, at the cost of an extra box. So Zigbee, Wi-Fi or Bluetooth bulbs are also chosen according to the installation already in place. A \u003ca href=\"\/collections\/ampoules-led-a-variateur\"\u003edimmable LED bulb\u003c\/a\u003e remains the solution when you only want to adjust intensity at the wall, without an app.\u003c\/p\u003e\n\n\u003ch3\u003eRGB bulb with remote: the solution without an app\u003c\/h3\u003e\n\u003cp\u003eThe supplied remote avoids the phone, the account to create and the network: you press, the colour changes.

E27 is the large screw base, found on most pendants, floor lamps and ceiling lights.
