Spotlights & Floodlights
Spotlights project a narrow, focused beam to highlight specific features like trees, statues, or architectural elements. Floodlights cast a wider beam to illuminate larger areas such as walls or garden beds. Both can be adjusted to achieve different lighting effects.
Well Lights
Well lights (also called in-ground lights) are installed flush with the ground surface, making them nearly invisible during daylight hours. These fixtures project light upward and are ideal for illuminating walls, columns, and tall landscape features without the fixture being visible.
Step & Deck Lights
These specialized fixtures are designed to be mounted on vertical surfaces of steps, stairs, or deck risers. They provide crucial illumination for safety while maintaining a subtle, unobtrusive appearance that complements your hardscape design.
Hardscape Lights
Hardscape lights are specifically designed to mount directly to outdoor structures like retaining walls, pillars, and under capstones. These low-profile fixtures create a wash of light across surfaces without being visually prominent themselves.
Specialty Fixtures
This category includes underwater lights for ponds and fountains, string lights for festive areas, and bollard lights for more substantial pathway illumination. Each serves specific decorative or functional purposes in your landscape lighting design.
Landscape Lighting Techniques and Design Principles
Understanding basic lighting techniques helps you create a more dynamic and professional-looking landscape lighting installation. These methods can be combined to create a cohesive lighting design that highlights your property’s best features.
Uplighting
Uplighting involves positioning fixtures at ground level to cast light upward onto features like trees, walls, or architectural elements. This technique creates dramatic shadows and highlights textures, making it ideal for showcasing the vertical elements in your landscape.
Downlighting
Also called moonlighting when installed in trees, downlighting positions fixtures above the area to be illuminated, casting light downward. This creates a natural-looking effect that mimics moonlight filtering through branches, producing gentle, dappled shadows on the ground below.
Silhouetting
This technique places lights between a feature and a wall or flat surface, creating a dramatic silhouette effect. The light washes the background while the foreground object appears as a dark outline, emphasizing its distinctive shape and form.
Cross Lighting
Cross lighting uses multiple fixtures positioned at different angles to illuminate a feature from several directions. This reduces harsh shadows and ensures the subject is well-lit from all viewing angles, making it ideal for focal points in your landscape.
Design Principle: Layering Light
Professional landscape lighting designs typically incorporate multiple lighting techniques in layers. Combine ambient lighting (overall illumination), task lighting (functional illumination of specific areas), and accent lighting (highlighting features) to create depth and visual interest throughout your outdoor space.
