Switching to all-LED at home: the room-by-room guide

Changing light bulbs every six months and watching your electricity bill climb is a daily reality for many homes still equipped with halogen bulbs. Switching to all-LED resolves both issues at once: each light source is replaced by an LED version chosen based on its base and room, for reduced consumption and a much longer lifespan.

Based on a survey of 144 pendant lights in our catalog on September 19, 2026, LED technology is present in 99% of the items: for manufacturers, the shift is almost complete. Now it remains to be carried out in your home without making mistakes. Our range of LED lighting allows you to keep your existing fixtures while modernizing the light, room by room.

Is it possible to install LEDs everywhere in a house?

Yes, every room can switch to LED, from ceilings to accent lamps. The only real nuance lies in the environment: a bathroom or an outdoor area exposed to splashes requires a suitable ingress protection (IP) rating, not the same bulb as a dry living room.

This is a point that generic guides forget. In our survey of 144 pendant lights, the IP20 rating dominates at 84%, compared to 7% for IP65, the value that resists water splashes. IP20 is suitable wherever it is dry; near a shower or a sink, you should aim higher.

As for the rest, it is all a question of the bulb base. Checking if you are using E27, G9, GU10, or E14 avoids unpleasant surprises, and our guide to bulb types helps identify yours. Once the base is known, our LED bulbs can directly replace your old ones.

Does an LED bulb get hot?

An LED gets very little heat compared to a halogen or incandescent bulb, which dissipated most of their energy as heat. The small electronic block warms up slightly, without posing a danger to a nearby lampshade. This is a real safety benefit in a child's bedroom or a closed closet.

This difference explains why replacing a halogen lamp with an LED model also changes the feel of a room: less heat, and stable light the moment you switch it on.

You then choose the ambiance. A warm white for a cozy living room, a more neutral white in a kitchen: the color temperature makes all the difference in comfort, for the same consumption.

What are the disadvantages of LED lamps?

The drawbacks are related to compatibility, not the technology itself. Not all LEDs are dimmable: in our survey, intensity adjustment was only confirmed for 35% of the entries. Plugging a standard LED into an old dimmer switch causes flickering or buzzing.

Before ordering a dimmable piece, it is better to distinguish between a dimmable bulb and verify that your dimmer is designed for LED loads. Otherwise, stick to a simple on/off setup without losing quality.

Doubtful about a base, an IP rating, or dimmer compatibility? You can ask our team for advice before outfitting a sensitive room like the bathroom.

Why do my LEDs stay on despite the switch being off?

An LED that remains dimly lit when the switch is off almost always indicates a wiring fault: the switch is cutting the neutral instead of the live wire, or residual current is still crossing the circuit. The electronic component of the LED is enough to glow with this trickle of current.

The fix involves correct wiring, sometimes removing a switch indicator light that allows some voltage to leak. To avoid this inconvenience during installation, it is better to know how to connect an LED safely and cut the power at the circuit breaker before any intervention.

Where to start, room by room?

Start with the rooms used most frequently: living room, kitchen, hallway—places where hours accumulate and where the savings are quickly visible. Then move on to ceiling lights, and finish with accent lamps and the bathroom, which requires the correct protection rating.

On the ceiling, an integrated LED model avoids the question of the base and provides homogeneous light; our LED ceiling light references cover living areas as well as hallways. It is often the most cost-effective replacement in a house.

To adjust power without over-lighting, think in lumens rather than watts. Our method to calculate the necessary lighting provides a reliable benchmark per room and per use.

Proceed in order so as not to forget anything:

• Note the base of each light point (E27, GU10, G9, E14).
• Choose the color temperature according to the desired ambiance.
• Check the IP rating in damp rooms.
• Verify dimmer compatibility before choosing any dimmable model.

Before buying in bulk, taking the time to choose your bulbs carefully will save you from returns. And in a social room, successful lighting changes everything: see how LED works in the dining room, above the table.

Each pendant light in our survey carries the CE certification and a 2-year warranty across all 144 entries examined: two concrete benchmarks when outfitting an entire house. The selection is also commented on by buyers, which can be viewed on the Google Designix page.

Converting a home to LED is neither long nor risky: it is a sequence of simple choices—base, rating, temperature—conducted room by room. Our lighting department brings together everything needed to outfit each space in the same spirit.
