Replacing xenon with LED: what really changes at home
This article is also available in French: Remplacer xenon par led
Check the base of the bulb you are replacing before ordering: E27, E14, GU10, G4 or G9. Also note the colour temperature and the current wattage. Xenon, for its part, belongs to the automotive world. At home, what you are replacing is a halogen, a spotlight or a fluorescent tube.
What gives the best light, xenon or LED?
For a car headlight, LED and xenon are on a par for brightness, with LED using less power and lasting longer. For a room at home, the answer is simpler: an LED gives better light than a halogen or a fluorescent tube, with three to five times fewer watts. Visual comfort then depends on the colour temperature.
A catalogue sorted by base and by use avoids mistakes when ordering, and that is exactly the principle behind our LED bulbs.
Why xenon is mostly heard of in the automotive world
Xenon is a gas used in discharge headlights and in certain arc lamps. It produces a white, very powerful light, reserved for road lighting. That is why a search for "replacing xenon with LED" brings back almost only headlight pages: xenon is not used in indoor light fittings.
At home, what you really replace with LED
- Halogen bulb with an E27 or E14 base, still common in bedside lamps and wall lights
- Halogen spotlight GU10 or 12 V, in kitchens and bathrooms
- Neon or fluorescent tube with a G13 base, in garages, utility rooms and hallways
- Classic incandescent, whose wattage is divided by five with LED
Good news: in most cases you keep the fitting and only change the source. An older light fitting often accepts an LED without modification, as long as the base and the dimensions match.
When the fitting itself is wearing out, replacing the whole pendant light sometimes costs less than improvising an adapter.
To fine-tune watt-for-watt equivalents, our LED bulb comparison sets out the most useful reference points.
Can LED bulbs be fitted to conventional light fittings?
Yes, in the vast majority of cases. An LED bulb replaces a halogen as long as the base, voltage and dimensions match. Spotlights and tubes can be changed too, sometimes by removing a transformer or ballast that is no longer needed.
Replacing a halogen bulb with an LED
Simply match the base and aim for the equivalent wattage. A 40 W halogen is replaced by a 5 to 6 W LED, a 60 W by an 8 to 9 W. The light produced is comparable, the heat given off much lower.
Two details matter: the shape, which must fit under the lampshade, and the colour of the light. Our guide to replacing a halogen with an LED details the most common equivalents.
Replacing halogen spotlights with LED spotlights
Two families coexist. GU10 spotlights run on 230 V: the swap is direct. 12 V spotlights depend on a transformer, to be kept if it powers other points, to be removed if it serves only that spotlight.
- GU10: direct replacement, no tools
- 12 V: check the transformer compatibility before buying
- Diameter: 50 mm remains the standard for recessed fittings
- Beam: 36° for general lighting, 24° for a worktop
The guide to switching a halogen spotlight to LED covers the tricky transformer cases.
Replacing a neon or fluorescent tube with an LED tube
The LED tube comes in two versions: with the ballast kept, or with the ballast removed. The second gives instant start-up and eliminates flicker. The G13 base and the length stay the same.
The step-by-step guide to replacing a neon tube works for a garage as well as a utility room.
If you are still torn between two bases for the same room, describe the fitting you have: contacting us is enough to settle it before ordering.
What are the drawbacks of LED bulbs?
Three criticisms come up again and again: a light sometimes judged cold, imperfect compatibility with older dimmers, and a higher purchase price than a halogen. In return, consumption drops noticeably and lifespan is counted in years. Most disappointments come from the choice of colour temperature.
On a five-bulb living room chandelier, going from five 40 W halogens to five 5 W LEDs lightens consumption without touching the look of the room.
Is LED lighting dangerous for the eyes?
No, as long as you choose good-quality light and do not stare at a bare high-intensity source. Domestic LEDs do not emit significant UV. Eye strain comes mainly from too strong a contrast between a dark room and a very bright point.
One rule of method: favour wide diffusion and moderate intensity. Our feature on going all-LED covers room by room the uses that tire the eyes least.
Colour temperature: the real criterion per room
It is measured in kelvins and decides the mood far more than the stated wattage.
- 2700 K: warm light, bedroom and reading corner
- 3000 K: warm white, living room and dining room
- 4000 K: neutral white, kitchen and bathroom
- 6000 K: cool white, garage and outdoors
A mix of temperatures in the same room is immediately visible. Our explanations on warm or cool light help you decide depending on the room.
Then there is the dimmer case: on an older installation, not all LED ceiling lights behave the same way, some buzz at low intensity.
Which source do you want to replace at home?
Which LED bulb should you choose for each room?
Start from the base, then from the use: a bedside lamp is chosen warm and low-powered, a kitchen is thought out in neutral white and with a directed beam. The base is read on the old bulb, the use is decided room by room. The protection rating depends on humidity.
Which base for which room?
From a survey of 250 references in our catalogue as of 29 September 2026, the base is stated on 226 listings: integrated LED and E27 are tied, at 26 % each, ahead of E14 (12 %) and GU10 (10 %).
| Base | Common use | Key point |
|---|---|---|
| E27 | Table lamps, pendants, ceiling lights | The most widespread, all formats |
| E14 | Bedside lamps, small lampshades | Slim format, modest wattages |
| GU10 | Recessed spotlights, kitchen, bathroom | 230 V, direct replacement |
| G4 | Small 12 V spotlights, furniture lighting | Check the transformer |
| G9 | Wall lights and compact fittings | Very small, watch the dimensions |
If a base remains unclear, the method to identify an E27 or GU10 base comes down to two measurements.
Changing the source is not always enough: when the fitting dates from another era, the LED lighting collection brings together 18850 references as of 29 September 2026, from the discreet ceiling light to the pendant that structures a room.
Which protection rating for a damp room?
The IP rating indicates resistance to dust and water. On the same survey of 250 listings, IP20 is stated on 94 % of references, IP65 on 4 % and IP44 on 2 %: most of the catalogue is aimed at dry rooms.
- IP20: bedroom, living room, office, hallway
- IP44: bathroom, outside the shower zone
- IP65: terrace, facade, poolside
- IP67: uses heavily exposed to water
Another useful reference point: the 2-year warranty is stated on the whole of this survey of 250 listings.
