Dimming depends on the bulb and the dimmer driving it. A bulb made for dimming says so on its packaging, and the dimmer itself must be LED-compatible, otherwise flicker, blinking or incomplete switch-off.\u003c\/p\u003e\n\u003ch3\u003eHow to recognise a dimmable GU10 bulb?\u003c\/h3\u003e\n\u003cp\u003eLook for the dimming wording on the box, or the wave-shaped icon. A standard bulb fitted behind a dimmer blinks, buzzes or refuses to light properly. A dimmable bulb also lights normally on a simple switch: it behaves like a classic bulb and only uses its dimming function when a dimmer drives it. Useful if you plan to fit the dimmer later. Sets already designed for dimming are found in \u003ca href=\"\/collections\/spots-led-a-variateur\"\u003eLED dimmable downlights\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eBulb or dimmer: which one decides the dimming?\u003c\/h3\u003e\n\u003cp\u003eBoth, and that is where most disappointments come from. The dimmer sets the adjustment range, the bulb must accept that range. A non-dimmable bulb fitted behind a dimmer does not follow the instruction: it blinks, switches off mid-travel or buzzes, and wears out faster. Technically the setup works, but the dimmer then only serves as a switch.\u003c\/p\u003e\n\n\u003ch2 id=\"compatibilite\"\u003eHow to tell if a dimmer is LED-compatible?\u003c\/h2\u003e\n\u003cp\u003eA dimmer is LED-compatible if dimming stays continuous from maximum to minimum, without flicker or buzzing. Older dimmers, designed for halogen, often expect a higher load than an LED provides: replacing them with a model built for LEDs solves most cases.\u003c\/p\u003e\n\u003ch3\u003eOld dimmer or LED dimmer: how to decide\u003c\/h3\u003e\n\u003cp\u003eSimple test: turn the brightness to maximum, then slowly down to minimum. The light should follow without jerks, without blinking, without hissing. If it drops out at the bottom of the range or switches off suddenly, compatibility is the problem. A halogen bulb of equivalent wattage serves as a control: if it dims well and the LED does not, the dimmer is at fault. At the bottom of the range, aim for dimmed light rather than total darkness. To change style along the way, take a look at \u003ca href=\"\/collections\/spots-orientables-coloris-blanc\"\u003eadjustable downlights in white\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eHalogen floor lamp with a dimmer: what to do with LEDs?\u003c\/h3\u003e\n\u003cp\u003eYou can fit an LED, provided the base matches and the dimmer accepts the load. With an old dimmer, the LED may flicker or switch off badly. Two outcomes: replace the dimmer with a model made for LEDs, or keep a filament bulb if the fixture allows it. Moving to LEDs often means adapting the dimmer, not just the bulb.\u003c\/p\u003e\n\n\u003ch2 id=\"veilleuse\"\u003eWhy does my LED bulb stay lit when the dimmer is off?\u003c\/h2\u003e\n\u003cp\u003eAn LED that stays faintly lit almost always comes from the dimmer: some let through a residual current strong enough to light an LED, while a filament bulb does not light. A quality dimmable bulb, or a dimmer designed for LEDs, most often removes this phenomenon.\u003c\/p\u003e\n\u003ch3\u003eFlickering and buzzing: the causes to check\u003c\/h3\u003e\n\u003cp\u003eThree causes keep coming back: too low a load for the dimmer, a non-dimmable bulb, or wiring to review, missing neutral or reversed live. Flickering at low brightness points more to the dimmer's minimum load. You rule out the leads one by one, starting with the bulb, then testing the same model on another circuit.\u003c\/p\u003e\n\u003ch3\u003eWhat to do if dimming drops badly or stops too early?\u003c\/h3\u003e\n\u003cp\u003eFirst check the number of bulbs behind the same dimmer: few LEDs on a dimmer designed for a high load give a short range. Then test a better quality dimmable bulb on the circuit. If nothing changes, the dimmer needs replacing. Residual current, for its part, often disappears simply by changing bulb model.\u003c\/p\u003e\n\n\u003ch2 id=\"poses\"\u003eRecessed, surface-mounted or adjustable downlights: which mounting to choose?\u003c\/h2\u003e\n\u003cp\u003eA recessed downlight sits flush with the ceiling and suits a hollow ceiling or a slab with clearance; a surface-mounted downlight is fitted when no cut-out is possible, for example under a concrete slab; the adjustable type is reserved for walls and worktops that need precise lighting.\u003c\/p\u003e\n\u003ch3\u003eIP44 GU10 dimmable downlights for a damp room\u003c\/h3\u003e\n\u003cp\u003eIn a bathroom, look at the ingress protection rating: IP44 generally covers water splashes around a bath or shower. For the rest of the room, a standard model is enough. Gradual light on waking, set by dimmer, beats a harsh switch-on.

A GU10 connects directly to the 230 V mains. A GU5.3 goes through a 12 V transformer, and its dimming then depends on the transformer as much as on the dimmer. An E27 base is found on pendants, wall lights and floor lamps. Before buying, check the base of the fixture already in place, not that of the bulb in your hand.

Prefer a recessed model in a hollow ceiling, surface-mounted on a solid slab, and adjustable to aim at a wall or a worktop.\"}},{\"@type\":\"Question\",\"name\":\"Are GU10 bulbs dimmable?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Not all: dimming depends on the bulb and the dimmer. A dimmable GU10 carries the corresponding wording on its packaging; a standard bulb fitted behind a dimmer blinks, buzzes or refuses to light. Both parts must be compatible for smooth dimming from maximum to minimum.\"}},{\"@type\":\"Question\",\"name\":\"How to tell if a dimmer is LED-compatible?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"You check by adjusting the brightness: continuous dimming, without blinking or buzzing, indicates correct compatibility. A dimmer designed for halogen often expects a higher load than an LED bulb provides, which makes lighting unstable. The LED dimmer wording remains the most reliable clue.\"}},{\"@type\":\"Question\",\"name\":\"Is it possible to fit a non-dimmable LED bulb on a dimmer?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Technically the setup works, but it is not advised: a non-dimmable bulb does not follow the dimming and may blink, buzz or switch off mid-range. The dimmer then only serves as a switch, with a risk of premature bulb wear.\"}},{\"@type\":\"Question\",\"name\":\"Why does my LED bulb stay lit even though the dimmer is off?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It is a residual current left by the dimmer: too low to light a filament, it is enough to make an LED glow. The phenomenon grows with an old dimmer or a low load. Replacing it with a model designed for LEDs, or choosing a better quality dimmable bulb, most often removes it.\"}},{\"@type\":\"Question\",\"name\":\"What problems can occur with an LED light dimmer?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The most frequent: flickering, buzzing, blinking, delayed switch-on, inability to dim low, or residual glow when the dimmer is off.
