How to Plan Landscape Lighting
Outdoor landscape lighting serves three purposes: safety (path and step lighting), aesthetics (accent and uplighting), and security (flood and motion lights). Each requires different lumen levels — more is not always better, especially for ambiance lighting where glare ruins the effect.
Path Lighting Spacing
For path lights in the 100-200 lumen range, space fixtures 6-8 feet apart. Brighter 250+ lumen fixtures can be spaced 8-10 feet. The goal is overlapping light pools without dark gaps. Stagger path lights slightly rather than perfectly aligning them for a more natural look. Fixtures should aim slightly downward, not outward (which creates glare at eye level).
Uplighting and Accent Techniques
For uplighting a tree, place the fixture 1-2 feet from the trunk aimed upward at 30-45 degrees. Use a narrow beam (15-30 degrees) for tall narrow trees; wider beams (30-60 degrees) for spreading canopies. For stone walls or textured surfaces, graze the light at a steep angle to create shadows that accentuate texture — this is called "wall washing."
12V vs Line Voltage
Low-voltage 12V systems are safe enough for DIY installation in most jurisdictions. A single transformer (150-300W) can power 20-40 LED path fixtures. Line voltage (120V) is used for high-output security floods and areas far from the transformer. All 12V wiring can be buried shallowly (6 inches) compared to 120V conduit requirements.

How many lumens do I need for landscape lighting?
Path and step lights: 100-200 lumens. Accent and spotlight fixtures: 200-400 lumens. Flood and area lights: 700-1300 lumens. Security lights: 1300-2000+ lumens. These ranges differ significantly from indoor lighting because outdoor fixtures illuminate specific objects or zones rather than entire rooms.
What is the difference between path lights and spotlights?
Path lights shine downward to illuminate walkways and borders at low height (typically 12-18 inches tall). They use diffuse, wide-angle light in the 100-200 lumen range. Spotlights (or accent lights) are directional fixtures that focus a beam on a specific object — a tree, sculpture, or architectural feature. They use 200-400 lumens with a narrow 15-45 degree beam angle.
Should I use 12V or 120V landscape lighting?
12V low-voltage systems are safer, easier to install (no electrician needed), and energy-efficient. They're ideal for path lights, accent spotlights, and deck lighting. 120V line-voltage systems are used for security flood lights, well lights requiring high output, and areas far from a transformer. Most residential landscape lighting uses 12V LED systems.
How far apart should landscape path lights be placed?
Typical path light spacing is 6-8 feet apart for standard 100-200 lumen fixtures. Brighter fixtures (250+ lumens) can be spaced 8-10 feet. The goal is overlapping pools of light without dark gaps, not maximum brightness. For a sophisticated look, stagger lights slightly rather than placing them in a perfectly uniform line.
