Landscape Lighting Design: How to Lay Out Path, Tree and Step Lights
Plan landscape lighting in zones, stagger path lights 5 to 15 feet apart, size uplights to each tree and keep the light warm and shielded. Here is the layout method, with the numbers.
Good landscape lighting design starts on paper: split the yard into zones, light the walks and steps people use, and pick one or two features worth showing. Then the numbers take over: path lights 5 to 15 feet apart and staggered, uplights matched to the size of each tree, and warm light at 3000K or lower.
Quick answer
Plan zones first (safety, accent, living), then place fixtures. Stagger path lights 5 to 15 feet apart, about 6 inches off the walk edge. Use one 35° uplight on a small tree, two on a medium tree and a mix of narrow and wide beams on a large one. Keep the light at 3000K or warmer and put each zone on its own schedule.
How do you design a landscape lighting layout?
To design a landscape lighting layout, walk the yard after dark, sketch it and split it into zones, such as safety, accent and living, each on its own schedule. Then place fixtures: path lights 5 to 15 feet apart and staggered, uplights sized to each tree, and warm light no higher than 3000K.
Start the plan with zones, not fixtures
Walk the yard after dark before you buy anything. On a sketch, mark where people walk, what is worth seeing (a good tree, a stone wall, the front of the house) and where people sit.
Those become your zones. Kichler recommends wiring each zone (a patio, a fire pit area, a group of trees) as its own circuit so it runs on its own schedule. A daisy chain, with every fixture wired in sequence, uses the least wire, but everything is either on or off.
A simple three-zone plan works for most homes:
- Safety: front walk, entry steps and driveway edge. On from dusk until late.
- Accent: trees, the front of the house and walls. Off at bedtime.
- Living: patio, fire pit and seat walls. On when you are out there.
If the yard itself is still being planned, lay out the spaces first with our guide to backyard layout. The lighting follows the same lines.
Path light spacing and placement
CAST Lighting recommends placing path lights 5 to 15 feet apart, staggered on both sides of the walk and set about 6 inches back from the edge. The goal is pools of light with softer gaps between them, not a continuous strip. Put extra light where people trip: steps, landings and any change in surface.
Start in the middle of that range, 8 to 10 feet, then adjust with the lights on. Steps and tight curves pull the spacing in. CAST also says to choose fixtures a little taller than the plants around them and to aim the light down at the walking surface.
The classic mistake is the runway: matched pairs of lights marching down both sides of a straight walk. Staggering fixes most of it, and so does skipping a fixture where a porch light already covers the walk. For walk shapes and widths, see our front walkway ideas.
| Feature | Fixture | Placement |
|---|---|---|
| Walks and paths | Path light with a downward spread | 5 to 15 ft apart, staggered, about 6 in. off the edge |
| Steps | Riser light or under-tread light | One per step |
| Seat or retaining wall | Hardscape light under the cap | Set before the cap goes on |
| Small deciduous tree | One 35° accent | Grazing the trunk, aimed into the canopy |
| Medium deciduous tree | Two 35° accents | Cross-lit from two sides |
| Large deciduous tree | One 15° plus two or three 35° or 60° | Narrow beam on the trunk, wider beams on the canopy |
| Larger fir | Two 60° accents | Set back from the base, aimed at the tree |
Uplight placement by tree size
Kichler’s tree lighting guide sizes the fixtures to the tree, as in the table above. A few details matter:
- Small tree: if people see it from two directions, use two 35° lights instead of one.
- Medium tree: two 35° lights beat one 60°, because narrower beams push more concentrated light into the canopy.
- Large tree (60 to 100 feet): the 15° light at the base covers the trunk up to the first branches, the wider lights sit away from the trunk, and one or two more can mount in the canopy pointing up.
- Firs: set the two 60° lights farther out and shine them onto the tree, not up into it.
A beam opens with distance: Kichler notes a 15° beam may spread to 20° or 30° by the time it reaches the canopy of a tall tree. Light one or two trees well instead of every tree a little.
Downlighting, or moonlighting
A tall tree near a patio can carry a downlight that throws branch shadows on the ground. Kichler places one 60° fixture at least 4 feet above the lowest branches, ideally 20 to 25 feet up, on a tree-mount box with about 2 inches of growing room and slack wire at the base.
Lights in steps, seat walls and retaining walls
Kichler’s hardscape lighting basics cover a light in the riser of each step or under each tread cap, lights on deck posts and railings, and 12-volt lights tucked under the top cap of a seat wall or retaining wall. Wall lights typically go in before the cap is set, and the wire needs a channel through the wall. That is the case for planning lighting with the hardscape, not after it. Our retaining wall ideas show the wall and seat wall types that take cap lights well.
Builder’s note: If lights are going into a wall or steps, run the wire while the block is going up, before the caps are set, and leave a little extra wire at every fixture. That slack lets someone pull the light out for service later without lifting the cap.
Color temperature, glare and dark sky
Color temperature is measured in kelvins (K), and the lower the number, the warmer the light looks. Under DarkSky International’s approval guidelines, residential fixtures cannot exceed a nominal 3000K and must dim to 10 percent or less of full output.
Kichler calls 2700K warm or soft white and suggests it for warm surroundings: brown or cedar, natural stone and red, orange or yellow foliage. Mixed color temperatures in one view make fixtures look mismatched, so pick one for each area.
Glare is the other half. The five principles from DarkSky and the Illuminating Engineering Society say outdoor light should be useful, targeted, no brighter than necessary, controlled and warm-colored. You should see the lit object, not the bulb. DarkSky’s neighborhood lighting guidance adds that properly directed, shielded lighting improves visual comfort and nighttime visibility by cutting glare, so the well-aimed fixture is also the safer one. Uplights send some light skyward by nature, so keep them tight to the target, low in output and fitted with a glare shield.
Controls, power and a word on wiring
Most landscape systems are low voltage. Kichler’s zone guide explains that the transformer converts household power to 12 volts, and recommends one with more capacity than you need now so added fixtures don’t cause voltage drop and uneven light. Transformer size, wire gauge and run lengths deserve their own plan, worked out before any trenching.
For control, the DarkSky principles call for timers or motion sensors, so light is on when needed, dimmed when possible and off when not. CAST notes that LEDs use 80 to 85 percent less energy than halogen lamps. And contact 811 a few days before anyone digs, even for shallow cable trenches: some utilities are buried just inches down.

Common landscape lighting mistakes
- The runway: evenly paired path lights on both sides of a straight walk.
- Too bright: high output everywhere flattens the yard. Light a few things well.
- Glare: bare lamps visible from seating areas, windows or the street.
- Cool white: higher-kelvin light looks bluer and harsher than warm white on stone and plants.
- One switch for everything: without zones, the patio lights burn all night.
- Fixtures that get buried: a path light that clears the plants in spring can disappear by late summer.
DIY or hire a pro
A plug-in low-voltage kit with a handful of path lights is a reasonable weekend project. Bring in help for a new outdoor outlet or any line-voltage work (an electrician’s job), lights built into new walls and steps, fixtures high in large trees, or several zones with long wire runs.
If you’d like the yard drawn first, our online landscape design plans lay out the patio, walls and planting to scale, and the zones above give you a starting point for the lights. To see where lighting fits in the rest of the plan, read our guide to hardscape design.
Frequently Asked Questions
How far apart should path lights be?
CAST Lighting recommends 5 to 15 feet apart, staggered on both sides of the walk and set about 6 inches off the edge. Start around 8 to 10 feet and adjust at night, adding light at steps and curves.
How many lights does it take to uplight a tree?
Kichler recommends one 35° light for a small deciduous tree and two for a medium one. A large tree gets a 15° light on the trunk plus two or three wider canopy lights.
What color temperature is best for landscape lighting?
Warm white, 2700K to 3000K, suits most homes. DarkSky Approved residential fixtures top out at a nominal 3000K, and Kichler recommends 2700K for natural stone, cedar and red, orange or yellow foliage.
Should landscape lights be on a timer?
Yes. DarkSky recommends timers or motion sensors so lights are off when nobody needs them, and wiring in zones lets the walk lights stay on later than the accent lights.
Can lights be added to an existing retaining wall?
Usually, but it is more work. Under-cap lights normally go in before the cap is set, so adding them later means lifting caps and finding a path for the wire.
How deep should low-voltage landscape lighting wire be buried?
Kichler’s installation instructions for its 12-volt landscape fixtures call for burying the cable at least 6 inches below the surface, and they say the thinner fixture lead wire is not meant for direct burial. The same sheet says not to install the fixture within 10 feet of a pool, spa or fountain. Call 811 before anyone digs.
What beam angle should I use for landscape lighting?
Kichler suggests starting with a 35° beam and adjusting from there. A narrow beam around 10° suits the top of a tall tree or the peak of a house, and a wide 60° beam fits conifers and other broad targets. A beam spreads wider the farther the fixture sits from what it lights, so placement matters as much as the angle.
Where should uplights go around a tree?
It depends on the tree. On a medium deciduous tree, Kichler aims the lights to graze the trunk while focusing on the canopy. On a large tree, a narrow beam sits at the base and the wider fixtures go away from the trunk. For dense trees and conifers, CAST Lighting says to place fixtures outside the drip line.
What is the difference between uplighting and downlighting?
Uplighting puts the fixture low and aims it up; Kichler calls it the foundational technique for trees, house fronts and landscape features. Downlighting, or moonlighting, mounts a fixture high in a tree and aims it down so the branches cast shadows on the ground. Kichler places it at least 4 feet above the lowest branches, ideally 20 to 25 feet up.
