An indoor green-wall design can benefit greatly from integrated horticultural LED lighting. This specialised light highlights the natural beauty of plants while creating an attractive, luminous atmosphere in your space. Here is what you need to know to choose and install light fittings for houseplants.
Why choose recessed horticultural LED lighting?
Successful indoor green walls need professional horticultural lighting. These recessed LED spotlights provide a suitable light spectrum while blending discreetly into your décor. Discover the ideal recessed LED spotlight for your green wall. These horticultural LED lights provide powerful illumination without taking up space, making them ideal for modern interiors.
A light spectrum suited to plant growth
The white light from these LEDs closely reproduces the natural spectrum plants need to grow. This technology is particularly effective for foliage plants, orchids and ferns, supporting photosynthesis with:
- Blue wavelengths (400–500 nm) : essential for foliage growth.
- Red wavelengths (600–700 nm) : encourage flowering and vivid colours.
With coverage of around 1 m² per spotlight, this horticultural lighting provides even intensity across your green wall. Tests show a 30% increase in foliage density after just four weeks of use.
Long life and low energy use
High-end LED technology provides an exceptional lifespan exceeding 50,000 hours, reducing maintenance needs. With outputs from 35W to 50W, these lights can save considerable energy while helping protect the environment.
The high-quality power supply provides stable, flicker-free light, creating a calm atmosphere for work or relaxation.
Thermal protection and no harmful UV
With no ultraviolet or infrared emissions, these grow lights protect plants while maintaining a suitable temperature. The anodised-aluminium cooling system allows installation close to leaves without scorching.
These completely silent lights are ideal for quiet spaces such as meditation rooms, bedrooms or work areas. Discreet and effective, they create a soothing light that highlights plants and supports wellbeing.
Types of lighting for indoor green walls
Several options are available for lighting green walls. The right horticultural lighting system depends on your layout, budget and preferred appearance. Good lighting must meet plant needs and fit harmoniously into your interior.
Recessed spotlights and horticultural LED bars
Waterproof recessed spotlights (IP66), available in depths from 100 to 155 mm, withstand the humidity of green walls. Discreetly installed in a suspended ceiling, these recessed green-wall lights provide precise illumination while remaining almost invisible.
- Adjustable spotlights : their 360° adjustment lets you direct light intensity to each part of the green wall.
- Horticultural bars : the XModule V5 150W model, for example, lights large areas evenly without creating hot spots.
- Modular tracks : adjustable LED lights adapt as the plants grow.
- Easy installation : pre-wired supports allow quick, configurable installation, even without advanced electrical skills.
For optimal lighting, position your light fitting around 90 cm from the green wall. This distance evenly illuminates an area of 1 m × 1.2 m. Available in white or anthracite, these systems suit modern plant-wall designs.
| Light fitting type | Output | Coverage area | Installation |
| Recessed spotlight | 35–50 W | 1 m² | Suspended ceiling |
| XModule LED bar | 80–150 W | 1.5–3 m² | Linear mounting |
| Modular track | 20–40 W per spotlight | Variable | Ceiling or wall |
| Flexible LED strip | 10–25 W/m | Custom outline | Perimeter or backlighting |
Adjustable tracks and flexible LED strips
Low-voltage IP65 LED strips (5–12V) are easy to install around a green wall. Paired with a dimmer, they let you adjust intensity to suit your needs. Their flexibility enables creative layouts that rigid lights cannot provide.
These discreet solutions fit neatly into a planted ceiling or false ceiling, creating a refined lighting atmosphere. Ideal for premium spaces such as showrooms and luxury boutiques, they highlight the green wall while remaining out of sight.
Installation and customisation of plant-wall lighting
A successful green-wall installation needs light fittings of high quality, as well as careful architectural integration. Learn how to customise your horticultural lighting, discover the best installation techniques and use smart controls to showcase your plants indoors.
Our 35W recessed LED spotlight has a 360° beam and 90° swivel CREE chips. It reproduces sunlight with the right intensity for healthy plant growth. Discover the ideal recessed LED spotlight for your green walls and combine horticultural performance with discreet styling.
Custom design and architectural integration
Our light fittings for an LED-lit artificial green wall suit many architectural styles: metal or solid-wood frames, round or rectangular designs and custom shapes up to 1 metre in diameter. These made-to-measure solutions integrate the light source into the structure for even illumination through foliage and moss.
Each installation can be adapted to alcoves, columns and reception areas. Elegant finishes and discreet profiles highlight the greenery, creating the impression of a real natural window.
- Wall-washing technique : an oval flood beam provides even light across the entire surface, eliminating dark areas with a minimum-to-average light ratio of ≥0.4.
- Optimum positioning : placing spotlights one-third of the way up the wall and aiming them from above reproduces the natural solar cycle and supports balanced plant growth.
- Quality control : a 25 cm photometric grid can be used to check light uniformity before completion.
- Certified references : our projects in Nantes, Bordeaux and Valencia demonstrate the performance and durability of our indoor plant-lighting solutions.
Smart lighting control and scheduling
Our connected lights allow precise spectrum and intensity adjustment (0–100%), with sunrise and sunset simulation. Turn your LED-lit artificial green wall into a dynamic ecosystem that adapts to the seasonal needs of your plants.
- Easy programming : synchronise 12-hour light cycles with irrigation to support growth and save energy.
- Natural variation : a 50W spotlight at 70% in the morning and 30% in the afternoon imitates natural changes in light.
- Simple installation : standard IEC connectors make it easy to wire more than 10 light points in series.
The technology can be adapted to each species: moderate intensity for ferns, strict dark phases for orchids, or bright light for succulents. With colour rendering above 95 , the colours in your plant display remain true, while the fitting lasts longer with less frequent maintenance.
Plant selection and simple care
Choose preserved plants such as goldenrod, amaranth or asparagus, which retain their natural appearance without watering or pruning and need little horticultural light. They are ideal for hard-to-reach spaces.
Our premium artificial plants are UV-resistant and have highly realistic textures, retaining their colour without natural light. Their exceptional colour rendering under our lights creates a polished appearance all year.
Maintenance is limited to dusting every three months with a microfibre cloth. Combined with durable CREE LEDs and metal or treated-wood structures, this simple care helps extend the life of your installation without affecting its appearance.
Frequently asked questions
How do you light an indoor green wall effectively?
