Wiring an LED to 220 V: what works and what burns out
This article is also available in French: Brancher led sur 220v
An LED bulb with an E27, E14, GU10 or G9 base screws straight into a 230 V socket, with no transformer or resistor. For a complete light fixture, connect live, neutral and earth to the existing 230 V output. Switch off the circuit breaker before identifying the wires.
How do you wire an LED to 220 V?
Three steps are enough: switch off the circuit breaker, identify the conductors, tighten the terminals. Nothing more is needed as long as the product is rated for 230 V. Only 12 V or 24 V models require an additional power supply.
- Switch off the circuit breaker for the relevant circuit
- Identify live, neutral and earth before touching the wires
- Tighten the terminals and check that no strand is sticking out
The rest comes down to one piece of information, written on the socket, the packaging or the label on the unit. An LED light fixture designed for 230 V connects like any other light point in a home.
The complete method, wire by wire, is detailed in our guide to wiring a light fixture safely. Keep it to hand if your installation is old.
220 V LED without a transformer: when it is possible
Whenever the product carries its own electronics. A 230 V bulb, a recessed spotlight sold as 230 V, an integrated LED pendant: all three connect to the output as they are.
Before stripping any wire, learn to recognise live, neutral and earth. Three colours, three roles, and one possible mistake on each.
On a DCL box
The DCL box is the ceiling base with its three terminals and cover. It serves as the connection point for a pendant or a ceiling light. It contains the same trio of conductors, with markings.
The step-by-step guide is here: installing a light fixture on a DCL box. Once the base is in place, changing the fixture takes a few minutes.
Do you need a transformer for an LED spotlight?
No if the spotlight is sold as 230 V: its driver is built into the housing or the base. The power supply becomes mandatory when the product is rated 12 V or 24 V. The voltage shown on the packaging is the only information that decides.
| LED source | What to put in between | Connection point |
|---|---|---|
| E27, E14, GU10 or G9 bulb | Nothing | Fixture socket |
| 230 V LED spotlight | Nothing, built-in driver | DCL box or recessed box |
| 12 V or 24 V LED strip | Power supply | The power supply receives the 230 V |
| 220 V LED strip | Nothing, rectifier supplied | 230 V output controlled by a switch |
A 230 V GU10 spotlight fits into a GU10 socket powered at 230 V. A spotlight of the same shape in 12 V requires a transformer per point, or one transformer for the whole line.
The power supply: choose it before the fixture
It is sized on total wattage, not on the number of points. Add up the watts, then look at the area to be lit. Our reference on watts per m² helps set the right wattage for a living room or a kitchen.
What the driver inside the fixture does
It rectifies the mains alternating current, steps down the voltage and stabilises the current. When it is built in, there is nothing to house or choose. When it is external, you need to plan an accessible location for it.
A fixture rated 230 V removes the transformer question, and that is the case for most of the models we list.
LED fixtures ready to connect to a 230 V output
Can you connect a 12 V lamp to a 220 V circuit?
No, never directly. A 12 V lamp connected to 230 V receives a voltage nineteen times too high and burns out within seconds. You need to put a 230 V to 12 V unit in between, or switch to an equivalent 230 V model.
A 12 V strip connected to a 230 V output
The strip heats up, the LEDs blow, and nothing limits the current. The correct connection goes through a unit whose wattage exceeds that of the strip, with a margin for heating.
The same reasoning applies to an old low-voltage halogen setup: it is better to replace a halogen with an LED than to tinker with the existing transformer.
Why an LED flickers when the power supply is unsuitable
Flickering often signals an undersized unit, an incompatible dimmer or a poor contact. The product works, but badly. Choosing a dimmable or variable bulb suited to the dimmer solves most cases.
Which fixture do you want to connect to your 230 V output?
How do you wire LEDs without a plug?
You start from a 230 V ceiling output or a wall recessed box, never from a plug. The switch cuts the live wire, the neutral stays connected permanently. This is the setup that powers a ceiling light, a pendant or a wall light from the wall.
220 V LED strip on a switch
A 220 V strip connects like a light fixture: live cut by the switch, neutral direct. The rectifier supplied with the kit goes between the output and the strip. An LED ceiling light follows exactly the same diagram.
What a two-way switch changes
Two switches control the same output, linked by a traveller wire. This is the usual setup for a living room pendant visible from the hallway.
A wall light with a built-in switch sometimes saves running an extra line. For a large living space, a dining room chandelier can also very well be controlled from two points.
Unsure about your fixture's voltage or the output's wattage? Describe your installation and we will tell you what connects and what needs to go in between.
Do LEDs need direct or alternating current?
Direct current to light up, but the mains alternating current suits them: the driver rectifies the 230 V and steps down the voltage. A 230 V socket bulb carries this electronics in its base, so there is nothing to add at the time of connection.
The conversion work remains invisible in use. Our guide to wiring an LED at home covers the details of common cases.
What resistor for a 220 V LED?
None, on a socket bulb: current limiting is already in the base. A resistor is only justified in a low-power electronic assembly, never in a domestic light fixture.
The sensitive point lies elsewhere. A dimmable LED poorly matched to its dimmer flickers, even when correctly powered. Check compatibility before replacing the bulb.
What our product pages say
Our LED lighting collection has 18,269 references as of 28 September 2026. On a sample of 250 of these pages on the same date, the declarations are clear:
