Quelle puissance LED pour l'éclairage extérieur ?

Comptez 5 à 10 W pour baliser une allée, 15 à 25 W pour une terrasse de 20 m², 30 à 50 W par projecteur pour une façade. La puissance se déduit de la surface et de la hauteur de pose. On part de la zone à éclairer, on passe par les lumens, et les watts arrivent en dernier.

Quelle puissance pour un spot ou un projecteur LED extérieur ?

Un spot LED extérieur se situe entre 3 et 10 W pour du balisage, 10 à 20 W pour une terrasse. Un projecteur démarre à 30 W et monte à 100 W pour couvrir une cour ou un parking. Le spot cible un point précis, le projecteur inonde une zone large.

3000 K ou 4000 K : quelle température de couleur pour l'extérieur ?

Choisissez 3000 K pour un extérieur de maison : la pierre, le bois et les feuillages y gagnent. Passez au 4000 K pour une allée partagée, un parking ou un commerce, où la lisibilité prime. En façade, le 3000 K vieillit mieux.

IP44, IP65 : quel indice de protection pour un luminaire extérieur ?

Retenez IP44 sous un auvent, une pergola couverte ou une avancée de toit. Passez à IP65 partout ailleurs : façade exposée, bord de terrasse, appareil posé au sol. Pour un point immergé, c'est IP67 .

What LED wattage for outdoor lighting?

Allow 5 to 10 W to light a path, 15 to 25 W for a 20 m² terrace, 30 to 50 W per floodlight for a facade. The wattage is derived from the surface area and the mounting height. You start from the area to be lit, go through lumens, and watts come last.

A balcony and terrace renovation never starts with wattage. You first draw what must remain readable in the evening: the step, the dining area, the wall.

Our selection of outdoor lighting reads the same way, by use rather than by displayed wattage.

How many lumens for outdoor lighting?

Allow 200 to 400 lumens for an entrance, 800 to 1,200 lumens for a 20 m² terrace, 2,000 to 4,000 lumens for a facade. Two fixtures of the same wattage do not light the same: the difference between lux and lumens explains why flux matters more than the advertised watts.

How many lumens per m² outdoors?

Aim for 50 to 100 lm/m² for an ornamental garden, 150 to 200 lm/m² for a terrace where you dine, 300 to 400 lm/m² for a staircase or an access area. Multiply by the surface area, divide by the number of light points, and you get the expected flux of each fixture.

This division avoids the most common mistake: a single floodlight in the middle of a long terrace leaves both ends in the dark. Two 15 W points spread out give softer light and a terrace and garden enhanced in the evening.

Under a pergola, the reasoning holds, with lower wattages and light that does not go up to the sky.

Path lighting: 5 to 10 W, 200 to 400 lm, 50 cm from the ground
Terrace of 15 to 20 m²: 15 to 25 W combined across two or three points
Entrance or gate: 10 to 20 W, beam directed towards the ground
Facade, large garden: 30 to 50 W per floodlight, mounted at 3 or 4 m

If your outdoor space requires several coordinated light points, write to us about your project: the choice of wattages is made together, on plan.

What wattage for an outdoor LED spotlight or floodlight?

An outdoor LED spotlight sits between 3 and 10 W for path lighting, 10 to 20 W for a terrace. A floodlight starts at 30 W and goes up to 100 W to cover a courtyard or a car park. The spotlight targets a precise point, the floodlight floods a wide area.

Path lighting: 3 to 5 W spotlight, narrow beam
Terrace: two or three 7 to 10 W spotlights
Courtyard, long path: 30 to 50 W floodlight
High facade: 50 to 100 W floodlight, directed downwards

What wattage for an outdoor LED spotlight?

3 to 7 W is enough for a recessed ground spotlight that highlights a wall, 7 to 15 W to light a flowerbed or a step. Above 20 W, a domestic spotlight becomes dazzling and casts hard shadows.

Our selection of outdoor LED spotlights is mainly about the beam angle, more than the wattage.

A sensor changes the game: a point that switches on as you pass can stay at 8 or 10 W and only light at the right moment. For this setup, see our guide on outdoor lighting with a sensor.

What wattage for an outdoor LED floodlight?

Allow 30 W for a 30 m² garden, 50 W for a courtyard, 100 W and more for a manoeuvring area. The range also depends on the angle: at equal wattage, a narrow beam reaches further than a wide beam.

For a path or an access, an 8 to 15 W outdoor post light often replaces two floodlights, with a lower and less aggressive rendering.

What LED wattage for solar outdoor lighting?

The panel caps the useful wattage: 3 to 10 W for a wall light or a bollard, 15 to 30 W only on models with a large panel. Brightness depends mainly on the battery and the hours of sunshine, not on the figure printed on the box.

For a path, an outdoor solar lamp avoids any cable laying.

A solar wall light is better suited to a facade far from the electrical panel.

Which outdoor area do you want to light first?

3000 K or 4000 K: which colour temperature for outdoors?

Choose 3000 K for a home exterior: stone, wood and foliage benefit. Move to 4000 K for a shared path, a car park or a shop, where readability comes first. On a facade, 3000 K ages better.

What is the difference between 3000 K and 4000 K?

Kelvin measures the hue of the light, not its wattage. 3000 K leans amber, 4000 K stays neutral, with neither yellow nor blue.

Marker	3000 K	4000 K
Hue	Warm white, close to halogen	Neutral white
Outdoor use	Terrace, facade, private garden	Shared path, car park, company entrance
Evening effect	Atmosphere, warmed materials	Visibility, uniform lighting

Is 3000 K light warm or cold?

It is warm. 3000 K sits just above a classic halogen bulb, a slightly amber white, never yellow. To place the markers between yellow, warm, neutral and cold, our article on white or yellow light covers the full scale.

Two habits: keep the same temperature on all points in the same space, and be wary of 6000 K, which turns facades blue and hardens materials.

IP44, IP65: which protection rating for an outdoor light?

Remember IP44 under an awning, a covered pergola or a roof overhang. Move to IP65 everywhere else: exposed facade, terrace edge, fixture placed on the ground. For a submerged point, it is IP67.

Can you put an LED bulb in any outdoor light?

No. Out of the 4,589 references of LED wall lights in our catalogue as of 28 September 2026, a survey of 165 product sheets gives the declared protection rating: IP20 in 85% of cases, IP65 in 8%, IP44 in 5%, IP54 in 1%. Barely 14% of this survey is therefore suitable for installation in an exposed outdoor area.

Technology is not the obstacle: on this same survey of 28 September 2026, LED is declared on 99% of the sheets and CE certification on 100%.

The useful habit remains the existing socket: most wall lights and lanterns take E27 bulbs, to be chosen in LED version and warm white to stay consistent with the rest.

Socket: identical to the bulb being replaced
Protection rating: at least equal to that of the light
Temperature: the same as the other points in the space
Wattage: never above the maximum marked on the socket

Can you use a more powerful LED bulb than the one intended?

Often yes, with two caveats: the socket and the heat. A more powerful bulb heats up more in a closed volume, and some lights indicate a maximum wattage not to be exceeded.

In practice, switching from a 40 W halogen to a 7 W LED is enough to gain light. Our guide to replacing a halogen with an LED gives the equivalents.

For a whole facade or a building, the reasoning changes scale: facade lighting is calculated in cumulative flux and projection distance.

Before buying your outdoor light

Identify the area: sheltered under an awning, exposed to rain, or in full sprinkler range
Note the protection rating required by that area: IP44 at minimum, IP65 if water falls on it
Read the colour temperature: 2700 to 3000 K for a warm mood, 4000 K for working light
Check whether the bulb is included or whether the light takes an E27, GU10 socket or an integrated LED
Check dimmability if you want to lower the light in the evening
Check the stated warranty: on our survey of 165 references as of 28 September 2026, it is 2 years in 99% of cases

Frequently asked questions about outdoor LED wattage

What wattage for outdoor lighting?

Allow 5 to 10 W per point for an entrance or a path, 8 to 15 W for a terrace and 10 to 20 W for a facade to highlight. Wattage alone says nothing: it is the combination of lumens and surface area that decides, and the protection rating that makes the light usable outdoors.

How many lumens for outdoor lighting?

A path is content with a few hundred lumens per point, a terrace sits around 1,000 lumens per point, and a facade needs rather 1,500 to 2,500 lumens if the wall must be readable. Multiply these markers by the number of points, not by the total surface area.

What is the difference between 3000 K and 4000 K?

3000 K is a warm white light, slightly amber, that flatters stone and wood; 4000 K is a more neutral white, almost cold, that renders colours more sharply. Outdoors, 3000 K extends the living room mood; 4000 K is reserved for work and traffic areas.

Can you use a more powerful LED bulb than the one intended?

Yes for an LED, provided you respect the maximum wattage marked on the socket and check that the circuit's power supply follows. A more powerful LED gives off little heat, but a closed light retains heat: stay within the range indicated by the manufacturer.

Which LED for outdoors?

Aim for an LED with a protection rating suited to the area, in E27 or GU10 socket if you want to be able to change the bulb, or an integrated LED if the light is sealed. On our survey of 165 wall light references as of 28 September 2026, only 8% declare an IP65.
