{"title":"Dimmable LED strips","description":"\u003cp\u003eDimmable LED strip lights are chosen first by their voltage (12 V, 24 V or 220 V) and by the dimmable mention on their datasheet, then by the white temperature. The dimmer must match the strip and its power supply, otherwise dimming flickers or stays stuck at full brightness.\u003c\/p\u003e\n\n\u003ch2 id=\"definition\"\u003eWhat is a dimmable LED strip and what is it for?\u003c\/h2\u003e\n\u003cp\u003eA dimmable LED strip is a strip whose brightness can be lowered and raised again with a compatible dimmer. It is used to adjust a ceiling outline, a niche or a piece of furniture without rewiring. The dimmer must match the strip voltage and the type of power supply.\u003c\/p\u003e\n\n\u003ch3\u003eDimmable LED strip: what it changes in the room\u003c\/h3\u003e\n\u003cp\u003eFixed indirect lighting imposes a single mood. A dimmer makes the same strip capable of a soft wash of light in the evening and a more readable level for reading or cooking. On a ceiling outline, it often replaces a second light source. \u003ca href=\"https:\/\/designix.fr\/collections\/rubans-led-pour-salon\"\u003eLED strips for living rooms\u003c\/a\u003e play mainly on this register, with a warm white that flatters woodwork and fabrics.\u003c\/p\u003e\n\n\u003ch3\u003eDimmer, dimmer switch or controller: do not confuse them\u003c\/h3\u003e\n\u003cp\u003eA dimmer switch lowers the brightness of a circuit. The dimmer often refers to the wall control or remote that drives this dimming. The controller manages the colours of a multi-channel strip. A single-colour strip is content with a dimmer switch, a colour version requires a dedicated controller, as on \u003ca href=\"\/collections\/rubans-led-rgb\"\u003eRGB versions\u003c\/a\u003e. To see the whole range, go through \u003ca href=\"\/collections\/luminaire\"\u003ethe Designix lighting catalogue\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2 id=\"dimmable\"\u003eHow do you know if an LED strip is dimmable?\u003c\/h2\u003e\n\u003cp\u003eAn LED strip is dimmable if its datasheet explicitly states that it accepts dimming and if the dimmer is compatible with its voltage. A non-dimmable strip may flicker or heat up with a dimmer switch. Check the manufacturer mention, the voltage and the type of signal before buying.\u003c\/p\u003e\n\n\u003ch3\u003eThe mentions to check on the product datasheet\u003c\/h3\u003e\n\u003cp\u003eThree lines matter: the supply voltage, the dimmable mention, and the type of control accepted (phase-cut dimming, 0-10 V signal, controller driving). A strip rated 12 V does not dim behind a mains dimmer switch without a suitable driver. The driver manual also gives the minimum load, below which dimming becomes unstable. Doubt is cleared by cross-checking both manuals, strip and power supply.\u003c\/p\u003e\n\n\u003ch3\u003eWhy some strips flicker with a dimmer\u003c\/h3\u003e\n\u003cp\u003eFlickering almost always comes from an incompatibility, not from a strip defect: load too low for the dimmer switch, non-dimmable driver, or strip length too short compared with the power supply threshold. Localised overheating appears when dimming is applied upstream of a driver designed for a fixed voltage. In that case, change the power supply or the control, not the strip. The detail of the models is in \u003ca href=\"\/collections\/rubans-led\"\u003eall the LED strips\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2 id=\"tension\"\u003e12 V or 220 V dimmable LED strip: which to choose?\u003c\/h2\u003e\n\u003cp\u003eThe choice depends on the strip power supply. A 12 V or 24 V strip works with a driver or transformer, and dimming is done via a compatible dimmer placed upstream. A 220 V strip connects directly to the mains with a suitable dimmer switch. The strip voltage and the dimmer voltage must match.\u003c\/p\u003e\n\n\u003ch3\u003e12 V dimmable LED strip\u003c\/h3\u003e\n\u003cp\u003eLow voltage requires a driver between the mains and the strip. The dimmer is placed upstream of the driver if it is dimmable, or downstream if it is designed for low voltage. The advantage of 12 V and 24 V remains safety and ease of connection in a piece of furniture or a niche. On long lengths, voltage drop is compensated by feeding both ends. See the \u003ca href=\"\/collections\/rubans-led-24v\"\u003e24 V LED strips\u003c\/a\u003e for long linear runs.\u003c\/p\u003e\n\n\u003ch3\u003e220 V dimmable LED strip\u003c\/h3\u003e\n\u003cp\u003eA 220 V strip connects directly to the mains, without a separate driver, which simplifies installation on a ceiling or a skirting board. In return, not all 220 V strips are dimmable, and the mention must be in black and white. The chosen dimmer switch must accept LED loads and the actual power of the strip.

Between two marks, the LEDs are wired in series: a cut in the middle leaves a dead section. Measure before cutting, counting the modules, and keep the offcut for secondary use rather than throwing it away. An aluminium profile is cut to the same dimension, which avoids adjustment during assembly.\u003c\/p\u003e\n\n\u003ch3\u003eConnecting after cutting\u003c\/h3\u003e\n\u003cp\u003eOnce the section is separated, connection is made with a clamp connector or by soldering onto the pads. Current direction matters: a strip connected backwards does not light up, without being damaged. The added or removed length changes the driver load, to be recalculated if you approach its limit. A signal amplifier takes over on very long linear runs. \u003ca href=\"\/collections\/rubans-led-rgbw\"\u003eRGBW strips with dedicated white\u003c\/a\u003e require the same rigour, with one more channel to respect.\u003c\/p\u003e\n\n\u003ch2 id=\"pieces\"\u003eWhich LED strip to choose for the living room, kitchen or a wet room?\u003c\/h2\u003e\n\u003cp\u003eFor the living room, a warm white 2700 K or neutral 3000 K suits a soft or readable mood. In the kitchen, choose a protected strip if the location is exposed to splashes. In a bathroom or near a pool, the waterproof version is essential.

A warm white 2700 K gives a rendering close to incandescent, a 3000 K stays sharper on a white wall.
