Austin Landscape Lighting Guide: Uplights, Path Lights & WLED

Landscape lighting transforms a yard that disappears at sunset into one that comes alive after dark. Done well, it extends your usable outdoor hours by four to five per night, adds curb appeal from the street, eliminates security blind spots, and reveals the landscape and architecture you invested in. Done poorly — or with box-store kits and guesswork — it creates glare, hot spots, dark holes, and the dreaded airport-runway look that makes your walkway feel like a landing strip.

This guide covers every fixture type, placement rule, wiring fundamental, and design technique you need to understand landscape lighting — whether you are planning a new system from scratch or evaluating what a contractor is proposing.

The Five Lighting Techniques

Professional landscape lighting uses five core techniques. Each creates a different effect, and the best designs layer all five together.

1. Uplighting (the workhorse)

Fixtures sit at ground level and aim upward to illuminate trees, architectural features, columns, walls, and focal points. Uplighting creates dramatic shadows, reveals texture, and defines the three-dimensional structure of everything it touches. It is the single most impactful technique in landscape lighting — a few well-placed uplights on trees and the house facade transform a property at night.

Placement rules:

• Trees: Use the 1-to-3 rule — place the fixture one-third of the tree’s height away from the trunk. A 15-foot tree gets a light about 5 feet from the base. Angle 30–60 degrees upward
• House facade: Place fixtures 1–2 feet from the foundation, angled 45–60 degrees upward. Space every 8–10 feet along the facade for even coverage
• Columns and pillars: One fixture at the base of each column, centered, angled straight up or slightly outward
• Textured walls (stone, stucco): Place close to the wall (6–12 inches) and aim upward at a steep angle to graze light across the texture, revealing depth and shadow in the surface

2. Downlighting

Fixtures mount above the area they illuminate — under eaves, soffits, pergola beams, or pavilion ceilings — and aim downward. Downlighting provides functional illumination for outdoor living spaces, cooking areas, and dining zones. It is the most natural-looking directional light because it mimics how we experience light indoors (from above).

Placement rules:

• Mount under eaves or soffits, spaced 6–8 feet apart for an even wash across the ground plane
• Under pergola beams, one fixture per beam or every other beam depending on spacing
• Under pavilion ceilings, use recessed or surface-mount fixtures on a 6–8 foot grid
• Keep fixtures behind the roof edge so the light source is hidden from ground-level sight lines — you should see the light effect, not the fixture

3. Moonlighting

A specialized form of downlighting where fixtures mount high in tree branches (15–25 feet up) and aim downward through the canopy. The result is soft, dappled light with natural shadow patterns on the ground — simulating moonlight filtering through leaves. Moonlighting is the most atmospheric landscape lighting technique and the finishing touch that separates a designed lighting system from a collection of fixtures.

Placement rules:

• Mount 15–25 feet high on a primary branch, aimed outward and downward at 45–60 degrees
• Use mature trees with broad canopies — live oaks are ideal in Austin
• Keep lumens low (150–300) to preserve the soft, subtle effect. Overpowered moonlights create harsh pools instead of gentle dappling
• Use 3000K for a slightly cooler tone that reads as natural moonlight rather than artificial light
• For large canopy trees, use 2–3 moonlighting fixtures on different branches to create overlapping shadow layers

4. Path lighting

Low fixtures along walkways, driveways, and garden edges that cast a downward pool of light onto the walking surface. Path lighting is functional first — it prevents trips and falls after dark — but it also contributes ambient ground-level glow that makes the landscape feel inhabited.

Placement rules:

• Space fixtures 6–8 feet apart using a staggered pattern — alternate sides of the path rather than placing fixtures directly across from each other
• Place 12–18 inches back from the path edge so they illuminate the surface without becoming trip hazards or getting clipped by mowers
• Use 100–200 lumens per fixture — path lights should glow, not glare. Each fixture should illuminate 2–3 feet of ground around its base
• At intersections and grade changes, add an extra fixture to mark the transition
• Avoid perfectly symmetric spacing — intentionally vary the interval by a foot or two for a more natural rhythm

5. FCOB strip wash lighting

FCOB (Flip Chip on Board) strip lighting produces a continuous, dot-free ribbon of light that is ideal for linear applications. It creates a wash effect — a soft, even glow along a surface — rather than the point-source illumination of traditional fixtures.

Applications:

• Under-cap wall wash: Mounted under the cap stone of retaining walls and seat walls so light washes down the wall face
• Step lighting: Under the nose of each step for a continuous line of light that defines the edge
• Under-rail deck lighting: Under the top rail of deck railings
• Cove lighting: Under pergola or pavilion eaves
• Pathway edging: Low to the ground along walkway edges as an alternative to path lights

Fixture Types and When to Use Each

Color Temperature: Choosing the Right Warmth

Color temperature is measured in Kelvin (K) and determines how warm or cool the light appears. This is the most critical decision in your lighting system after fixture placement.

• 2700K (warm white): The standard for residential landscape lighting. Warm amber glow that complements stone, wood, and earth tones. Use this as your default
• 3000K (neutral warm): Slightly crisper and cleaner. Makes green foliage pop. Good for modern and contemporary designs, and for moonlighting where a cooler tone reads as more natural
• 4000K+ (cool white to daylight): Commercial and institutional. Never use for residential landscape lighting — it creates a cold, sterile, parking-lot feel

The critical rule: Match every fixture and strip in the system to the same Kelvin temperature. Mixing 2700K uplights with 3000K FCOB strips creates a visible color mismatch that looks unintentional and distracting. Pick one temperature and commit.

Designing a Lighting Plan

Step 1: Walk the property at night

Before selecting a single fixture, walk your property after dark with a bright flashlight. Aim it up at trees from different angles, wash it across walls, point it down paths. This exercise reveals which features are most dramatic when lit and from what angle. Take notes or photos — what looks best when lit from the left may look flat when lit from the right.

Step 2: Identify the priority features

Not everything needs lighting. Prioritize:

1. Trees — the most impactful single element to light. Mature live oaks, pecans, and cedars are stunning when uplighted
2. House facade — defines curb appeal at night
3. Walkways and steps — functional safety, non-negotiable
4. Retaining walls and seat walls — FCOB under-cap wash is transformative
5. Outdoor kitchen and dining — task lighting for cooking, ambient for dining
6. Water features — if you have one, light it
7. Specimen plants and garden art — accent lighting as the finishing layer

Step 3: Layer the techniques

A complete lighting design layers multiple techniques. Here is what a typical Austin backyard system looks like:

Wiring and Technical Fundamentals

Low voltage vs. line voltage

Residential landscape lighting runs on low voltage — 12V or 24V DC — stepped down from your home’s 120V AC by a transformer. Low voltage is safer (no electrocution risk from buried wire), does not require an electrician for the landscape portion, and allows flexible fixture placement. The only line-voltage component is the outlet the transformer plugs into, which does require a licensed electrician if one does not exist.

Transformer sizing

The transformer is the power supply for the entire system. Size it using the 80% rule: total fixture wattage should not exceed 80% of the transformer’s rated capacity.

• Add up the wattage of every fixture and every foot of FCOB strip on the system
• Divide the total by 0.8 to get the minimum transformer size
• Example: 200 watts of fixtures ÷ 0.8 = 250-watt transformer minimum
• For systems over 300 watts, split into multiple transformers on separate circuits for redundancy and easier voltage management

Wire gauge and voltage drop

Voltage drop is the enemy of landscape lighting. As current travels through wire, it loses energy to resistance — the longer the run and the thinner the wire, the more voltage drops. Fixtures at the end of a long, thin wire run will be noticeably dimmer than fixtures near the transformer.

Wiring layouts

• Hub-and-spoke (best): Transformer feeds a central junction box, and individual wire runs branch out to each fixture group. Keeps all runs short and voltage drop consistent. Professional standard
• Daisy chain (acceptable for short runs): Fixtures connect one after another along a single wire run. Simple but prone to voltage drop at the end of the chain. Only use for 3–4 fixtures on runs under 50 feet
• T-method: Wire runs from the transformer to the middle of a fixture group, then branches in both directions. Balances voltage drop across both halves. Good for long rows of path lights

Connections

Every connection point is a potential failure. Use waterproof, gel-filled wire connectors rated for direct burial. Never use standard wire nuts wrapped in electrical tape underground — moisture will corrode the connection within 1–2 seasons, causing flickering, dimming, and intermittent failure. Most landscape lighting service calls trace back to corroded connections, not failed fixtures.

Sample System Designs

Common Mistakes

• Too many path lights, not enough uplights. Path lights are the first thing homeowners buy, but uplighting trees and the facade creates 80% of the nighttime impact. Start with uplights, add paths second
• Using box-store kit fixtures. Plastic housings, 16-gauge wire, undersized transformers, and 4000K color temperature. They fail within 2–3 years and produce unflattering light. Professional fixtures cost more upfront but last 15–20 years
• Symmetric path light spacing. Evenly spaced lights in a straight line on both sides of a path creates the airport runway effect. Stagger placement, vary spacing slightly, and keep fixtures on alternating sides
• Mixing color temperatures. 2700K uplights with 3000K path lights with 4000K step lights. The eye notices instantly. One temperature for the entire system
• Undersized transformers. Running a transformer at or above capacity shortens its life and causes voltage fluctuations. Use the 80% rule and leave room for future additions
• Pointing lights at eye level. Every fixture should be aimed so the light source is invisible from normal sight lines — sitting, standing, and walking. If you can see the bulb, the fixture is poorly aimed
• Forgetting the first-fixture rule. The first fixture on a wire run should be at least 10 feet from the transformer. Fixtures too close to the transformer receive excess voltage and burn out faster
• Tape-wrapped wire nuts underground. Use waterproof gel-filled connectors. Every time. No exceptions
