Garden analysis

Before starting any garden lighting project, conducting a thorough area analysis is fundamental. Consider landscape characteristics, plants layout, architectural elements, and pedestrian flows. Identify focal points and areas that require specific emphasis. It’s advisable to plan systematically, dividing the garden into thematic areas, identifying elements and spaces to be illuminated such as:

• Pathways – pedestrian connections linking various garden areas and also connecting the lot access to the residence, garage, etc. Make sure not to leave dark areas, especially near steps, thresholds, etc. Avoid overly strong or misdirected lights that could dazzle and consume excess energy, ensuring the right comfort for walking paths. Common solutions include recessed spotlights near walls or low walls, walkover lights with grazing light (to be planned before laying the pavement), or bollards;
• Living, dining, relaxation areas – frequently used zones where the garden is enjoyed and where most time is spent. These areas need horizontal and vertical illumination. For instance, illuminating the dining table area for evening meals discreetly yet functionally. You can consider suspended lights for pergolas, floor-standing lamps, or other original solutions. If there’s an outdoor kitchen or barbecue, think of light points that make the cooking area visible without disrupting the ambiance. In relaxation areas, there can be numerous design solutions to experiment with, from floor lamps to wall lamps, table lamps, LED strips or luminous furnishings (seats or vases), etc;
• Vegetation – consider the size of plants during their growth and pay attention to their shape, leaf color, flowers, etc. For example, tall trees should be illuminated from bottom to top, perhaps with an adjustable spotlight, to highlight their tall forms and branch texture. Bushes up to 80 cm tall can be illuminated from top to bottom with lanterns that enhance their shapes and colors. Another solution is using recessed spotlights or projectors that illuminate from bottom to top, filtering light through the foliage;
• etc.

Light Selection

Choosing the right lights is crucial. Apart from aesthetics, consider functionality and energy efficiency. Remember, these lights remain on for many hours, so consumption shouldn’t be overlooked.
LED lights offer flexibility and energy savings. Choose color temperatures that suit the desired atmosphere: warm tones for a welcoming ambiance, neutral tones to highlight details and natural colors, and cool tones for a more modern feel. For instance, barbecue areas, fireplaces, and kitchens require neutral tones, around 4000 K. Generally, warmer shades work better for illuminating greenery and relaxation areas, below 2700/3000 K. Above 4000 K, lights are usually reserved for more architectural elements like fountains, walls, or structures.

LED light temperature

With garden design software, after creating the 3D garden model, you can insert lighting fixtures, adjust light intensity and temperature, and experience the desired effect. Simulate various lighting effects (diffused light, spotlights, LED strips, etc.) at different times of the day and assess the impact of artificial light on the landscape and garden structures in various lighting conditions, optimizing the placement of light points for impactful aesthetic effects. Moreover, through the use of a 3D BIM model, conduct in-depth analyses of lighting energy efficiency. This includes energy consumption simulations, assessments of LED or other low-consumption technology use, and optimizing lighting to reduce energy wastage. Finally, use the BIM model as a real-time model control tool and utilize IoT platforms to manage lighting (switching on and off times, light intensity, etc.), as well as water systems, video surveillance, alarms, etc.

Where it’s not possible to install a new system, there are solutions on the market that don’t rely on electrical connections, such as solar-powered or battery-rechargeable options. These enable illumination even in the farthest corners of the garden without the need for excavations or connections. Additionally, they offer the advantage of being movable based on needs.

Aside from light, careful consideration should be given to the type of support. There are lamp posts, various-height bollards, step markers, directional spotlights, wall lamps, and numerous other variants with classic or modern, minimalistic, or decorative forms and materials. Calculating the distance between lighting fixtures is crucial to avoid unnecessary light dispersion or leaving completely dark areas.

Lighting effects and techniques

In garden lighting projects, manipulating light is an art form that transforms outdoor spaces into captivating settings. Effectively utilizing lighting effects and techniques can highlight natural and architectural beauty, creating engaging atmospheres. Here are some insights into lighting techniques and effects:

• Uplighting and downlighting – uplighting involves illuminating upwards to emphasize vertical elements like trees, sculptures, or architecture. This technique creates a significant visual impact and adds drama to the nighttime landscape. On the other hand, downlighting illuminates from above to below, providing soft and diffused light useful for lighting pathways, seating areas, or flowerbeds without creating annoying or dazzling reflections;
• Backlighting and silhouette lighting – backlighting involves placing light sources behind the object you want to highlight. This technique can create a contour effect, outlining plants or structures, producing a magical atmosphere, and emphasizing the garden’s depth. Silhouette lighting, meanwhile, creates silhouettes of objects or plants by positioning the light source between the observer and the element, highlighting its contour in a suggestive manner;
• Washing and grazing techniques – washing involves evenly spreading light on a wall or a wide surface, creating a soft and uniform atmosphere. This technique is often used to highlight walls, hedges, or decorative walls. On the other hand, grazing illuminates a surface from above or below to highlight textures or details, emphasizing the contours and specific features of elements;
• Dynamic and colored effects – besides basic techniques, employing dynamic and colored effects can add depth and personality to the garden. Using dynamic lights, such as projectors with movement effects, can create exciting and changing environments. Using colored lights, through filters or RGB lights, allows changing the atmosphere and adapting it to specific events or seasons;
• Light mixing – another key aspect is mixing different color temperatures and light intensities. Using lights with various tones and directions can create interesting contrasts and dynamically shape the space, allowing you to play with illusions and depth;
• Shades and pinpoint light – light can be used to create shades through the use of diffusers or semi-transparent materials. This technique can be particularly effective in creating a soft and romantic atmosphere. Using pinpoint light, such as directional spotlights or recessed lights, allows emphasizing specific details without excessive light dispersion.

5 rules to remember

To conclude, let’s recap the 5 things to remember in a garden lighting project:

1. Illuminate hedges and borders – To ensure visibility of the border, two approaches are possible:
   • If there are flower beds in front of the hedge, it’s advisable to install adjustable spotlights that project light directly onto the hedge. This creates a luminous barrier that defines a distinctive boundary. If walls replace hedges, LED strips placed at the base will draw a luminous border along the perimeter. However, it’s essential to avoid projecting light inwards, as it could dazzle people in the garden;
   • In cases where there are no flower beds, lanterns can be placed within the hedge, directing light downwards to outline the boundary through luminous spots among the leaves. If an outdoor area with a dining table is planned, it’s crucial to avoid obstructing the view with annoying lights. Additionally, illuminating towards the house might pose a safety risk.
2. Illuminate pathways with recessed lights – Safety is a priority in garden lighting. It’s essential to illuminate pedestrian pathways and driveways with recessed spotlights, to be arranged before laying the pavement. This solution ensures the safety of pedestrian paths and garage access ramps, reducing the risk of accidents due to poor visibility. Light sources should always be shielded by anti-glare filters to avoid discomfort during walking;
3. Illuminate trees based on height and leaf characteristics – Garden trees offer an opportunity to create an evocative atmosphere. However, not all trees require the same type of lighting. For tall trees, it’s advisable to illuminate them from bottom to top with an adjustable outdoor spotlight. However, trees with broad and dense leaves are not suitable for this type of lighting as they cancel out the interplay of light and shadow;
4. Illuminate low plants from above – Plants ranging from 30 to 80 centimeters in height should be illuminated from top to bottom;
5. Integrate lights into vegetation for a discreet effect – To make garden lighting more captivating, it’s advisable to hide light sources within vegetation. This way, attention will be focused on the plants rather than the light sources, creating a more natural and engaging effect.
