There's nothing like that first evening spent on a well-lit balcony to immediately feel the difference: the air cools down, the light creates a soft ambiance, and what was "just an outdoor corner" becomes a true extension of the living room.
Four simple rules are all it takes to transform your space: appropriate brightness (lumens) , a suitable IP rating , a warm color temperature , and thoughtful placement . Do some of the terms seem too technical? Don't worry. Our team has created an article to help you understand everything so you can then effectively light your outdoor space.

1) Why choose a wall light for a balcony/terrace?
Outdoor wall lights are compact, easy to install, and particularly well-suited to spaces like balconies or patios. A tip: install one near a lounge area or outdoor table. This is often enough to transform your space from purely functional to inviting. Minimalist and sleek wall lights are also frequently used outdoors.
2) Power & lumens: how much light?
Good lighting isn't just about "lots of light," but about "the right amount for the purpose." For a standard balcony or terrace, aim for 300-600 lumens (check the bulb packaging for this information) per wall light. The larger or more functional the space (dining, reading), the higher the lumen output will need to be.
Below is a table with our recommendations for different types of spaces:
| Space | Use | Lumens indicator |
|---|---|---|
| Small balcony (2-4 m²) | Gentle atmosphere | 200–400 lm |
| Medium-sized terrace (6-12 m²) | Atmosphere + traffic | 300–600 lm |
| Dining/reading area | Functional | 600+ lm or multiple points |
3) IP rating & materials: choose for outdoor use
The logic is simple: the more exposed the light is to the elements, the higher the IP rating should be. For a covered balcony, IP44 may suffice. For an unprotected facade, aim for IP65 or higher.
Suitable materials
- Aluminium / stainless steel : lightweight, corrosion resistant.
- Treated steel / brass : strong, but be careful with the finish when exposed to sea.
- Polycarbonate / technical plastic : ideal for solar applications, but choose UV-resistant.
4) Placement, height and spacing
To avoid glare and obtain pleasant light: place the wall light between 1.8 m and 2.5 m high. If you have a long wall, space your wall lights every 3-4 m depending on the beam pattern.
5) Color temperature & rendering (CRI)
To create that inviting outdoor space, opt for warm lighting (2700-3000 K). This is confirmed by French experts who recommend 2200-3200 K as ideal for outdoor use.
French regulations: The Decree of December 27, 2018 imposes a maximum temperature of 3000 K in certain contexts to limit blue light.
6) Suitable wall light types
- Wired LED: powerful and reliable, often dimmable. Requires wiring.
- Solar: easy wireless installation, a good renovation option. Check battery life.
- Motion detector (PIR): ideal for entrances/frequented areas — beware of false triggers.
- Adjustable / dual emission: aesthetic to highlight wall + floor, create light effects.
7) Installation & safety
- Turn off the power before any intervention.
- Suitable IP rating: IP44 minimum for covered balconies, IP65+ for exposed facades.
- Fixing and sealing: prevent water infiltration or corrosion.
- For solar panels: install them where they receive good direct sunlight.
- If in doubt, call a qualified electrician.
8) FAQ: Frequently Asked Questions
For a standard balcony, 300-400 lm is sufficient for ambiance; 500-600 lm if meals or reading are regular.
Yes, if the light fixture is sheltered (awning, covered balcony). Otherwise, for a facade directly exposed to rain, choose IP65+.
2700 K is warmer; 3000 K offers slightly more contrast without appearing cold. In any case, stay below 3000 K to limit blue light.
