Quick Answer
Planning a landscape lighting layout takes 6 steps: (1) walk your yard at dusk, (2) decide what to highlight, (3) pick the right light type for each spot, (4) count how many fixtures you need, (5) size your transformer, and (6) map your low-voltage wire runs. Most homeowners can plan a full backyard in about an hour — no electrician required.
Why Planning Matters Before You Buy
Most people buy landscape lights the way they buy patio furniture — they see a photo, pick what looks good, and hope it works. That's how you end up with too few lights, a transformer that's too small, or wires that run across your whole yard.
A good plan before you order saves you two things: return shipping and weekend regret. Here's the step-by-step process we walk customers through before they place an order.
Step 1: Walk Your Yard at Dusk
Don't plan this in the afternoon. Wait until 30 minutes after sunset, when the sky is just dark enough, and walk your yard with a notebook. Mark:
- Tripping hazards (steps, uneven path edges)
- Architectural features (the stone facade, a big tree, a water feature)
- Areas where you actually sit (patio, fire pit, dining table)
- Dark corners where neighbors' lights leak in
You're not designing a lighting showroom — you're figuring out where you need light to be safe and where you want light to feel nice.
Step 2: Decide What You're Actually Highlighting
Not every light does the same job. There are three main jobs, and each needs a different fixture:
| Job | What it does | Fixture type |
|---|---|---|
| Safety | Lights paths, steps, and trip hazards | Path light |
| Highlighting | Pulls a tree, wall, or statue into view | Spotlight / well light |
| Ambience | Warm glow on a patio or seating area | String light / deck light |
Most homes need all three. Don't try to solve everything with one fixture type.
Step 3: Pick the Right Light for Each Spot
Once you know the job, pick the fixture. We break this down in Path Light vs Spotlight vs Well Light, but the short version:
- Path lights line walkways and driveways — space them 6 to 8 feet apart.
- Spotlights point up at trees, walls, and flags — one per feature.
- Well lights sit flush in the ground for soft uplighting on plants and fences.
- Deck lights recess into steps and railings for safety.

Step 4: Count How Many Fixtures You Need
A simple rule of thumb:
| Area | How many lights |
|---|---|
| Walkway (30 ft) | 4–5 path lights |
| Front entry | 2 path lights + 1 spotlight on the house |
| Backyard patio | 2–3 spotlights on trees + string lights |
| Steps | 1 deck light per step riser |
Add up the total wattage (most LED fixtures are 3–5W each). That number tells you the transformer size you need — see our transformer sizing guide.
Step 5: Size Your Transformer
This is where most people go wrong. Your transformer needs to handle the total wattage of all fixtures plus a 20% buffer. If you have 12 fixtures at 5W each, that's 60W — get a 100W transformer minimum, not a 60W one.
For larger yards (20+ fixtures), a 600W transformer like our MLR-TF04 gives you room to expand later. You'll thank yourself next year when you want to add lights by the fire pit.
Step 6: Map Your Wire Runs
Before you dig, sketch how the low-voltage wire will run:
- Start at the transformer (mounted near an outdoor outlet)
- Run the main wire to the farthest light
- Tap off to each fixture along the way
- Hide wire under mulch, in a shallow trench, or behind shrubs — see our 5 ways to hide landscape wire
Keep wire runs under 100 feet for the brightest result. Longer runs cause voltage drop — we explain the math in our wire length guide.

Should I buy lights before planning the layout?
No. Plan first, then buy. Ordering lights before you've mapped the yard usually means you end up with the wrong count, wrong wattage, or both. Spend an hour with a notebook and tape measure first — it's worth it.
How many lights can I put on one transformer?
Add up the wattage of every fixture (usually 3–5W each), then pick a transformer rated at 20% more than that total. A 100W transformer handles about 18–20 standard LED path lights. For larger yards, size up — you can always expand.
What's the first step in planning landscape lighting?
Walk your yard at dusk with a notebook. Mark where it's dark, where you trip, and what you want to highlight. Don't start with shopping — start with observation.
Do I need an electrician to install landscape lights?
No. Low-voltage landscape lights run on a 12V transformer that plugs into a standard outdoor GFCI outlet. Most homeowners install them in a weekend with a screwdriver and a shovel. If you have a large yard or want to wire a main line into your house panel, that's when you call an electrician.
