Quick answer
Landscape lighting is the set of outdoor fixtures that light paths, steps, plants, walls and entries for safety and appearance, powered by low-voltage wiring, by the sun through solar cells, or by line voltage from the house.
The three power types differ most in who may install them. Low-voltage and solar systems are common homeowner projects. Line-voltage wiring is electrical work for a licensed electrician. Good design also limits glare and sky glow.
Quick facts
The key facts about Landscape Lighting, with sources:
Key takeaways
- Landscape lighting comes in three power types: low voltage, solar and line voltage. The type decides the wiring, the safety rules and who may install it.
- Do not wire line voltage yourself. Manufacturer instructions say to consult a qualified electrician and local code before installing any electrical product.
- A low-voltage transformer plugs into a covered, weatherproof GFCI outlet. Manuals say never to use an extension cord.
- Good lighting is shielded, aimed down, warm in color and no brighter than needed. The National Park Service and McDonald Observatory give the same advice.
- HOAs and local lighting ordinances can limit fixtures, so check before you buy.
Light for a purpose, not for coverage
Landscape lighting puts light where people walk, sit or look. It marks steps and paths, shows off a tree or a wall, and makes an entry easier to find. It is not a floodlight on a wall.
Iowa State’s extension writer lists the common fixture groups: tier or accent lights that define paths, mushroom lights for low borders, floodlights aimed along fences and walls, step and surface lights for safety, and well lights set at ground level to shine upward 4.
The best advice is the shortest. The National Park Service says to ask first whether a light is needed at all, then light only the task area 1. McDonald Observatory says lights “should have a clear purpose” 3.
That mindset keeps a yard from looking like a runway. The same Iowa State article warns against overlighting and says a subtle effect is usually better 4.
The three power types
| Type | How it is powered | Who usually installs it | What to watch |
|---|---|---|---|
| Low voltage | A transformer plugs into a 120-volt outlet and steps power down to 12 or 15 volts for the fixtures 54 | Often a homeowner or a landscape lighting contractor; a licensed electrician if no proper outlet exists 56 | GFCI outlet, no extension cord, load limit of the transformer, wire length 56. See low-voltage landscape lighting |
| Solar | A panel charges a battery in each fixture or on a separate panel; no wiring | Homeowner | Output depends on sun exposure and season; no primary source loaded for run times |
| Line voltage | Fixtures run on the house’s 120-volt supply through wiring in conduit or cable | A licensed electrician | Local electrical code and inspection; manuals say consult a qualified electrician 5 |
Never do line-voltage work yourself
Line-voltage wiring, new circuits, junction boxes and receptacles are electrical work. Toro’s transformer manual says to consult a qualified electrician and local electrical codes before installing any electrical product and warns of serious injury from shock 5.
Turn off the breaker, and let a licensed electrician do it. Call 811 before digging for any cable run.
How a low-voltage system is laid out
Most yard systems are low voltage. A transformer sits on a wall near a covered outdoor outlet. A cable runs from it out into the beds. Fixtures attach along the cable.
The transformer has a total wattage it can supply, and the fixtures together must stay under it.
Ring’s transformer manual gives a 200-watt maximum as an example of a rating 6, and Toro’s manual says the amperage should not exceed the rating posted on the transformer door 5. Your transformer’s label sets yours.
Placement matters. Ring says to mount its unit more than 1 foot above the ground and the Volt manual says the bottom plate should be at least 1 foot up 67.
Toro’s says to locate its cabinet 4 feet above grade within 4 feet of a GFCI outlet 5. The numbers differ, so follow your own product’s manual.
Fixtures at the far end of a long cable can come out dimmer. That is voltage drop, covered on the low-voltage landscape lighting page. A timer, photocell or smart control decides when the lights run.
- GFCI outletCovered, weatherproof, no extension cord
- TransformerSteps 120 volts down to the rated output
- Cable runRated low-voltage cable to the beds
- FixturesTotal load under the transformer rating
- ControlTimer, photocell or smart control
Example: checking a yard light against the National Park Service steps
The National Park Service gives a six-step test for any outdoor light 2. The example below applies it to a floodlight on a back wall. The inputs are an invented example. The tests are the Park Service’s.
| Step | The question | What the example light shows |
|---|---|---|
| 1. Light only if needed | Is this light needed at all? | It lights a gate people use at night. Keep it. |
| 2. Light only when needed | Can a motion sensor or timer limit it? | It burns all night. Add a motion sensor or timer 2. |
| 3. Light only where needed | Is it shielded and aimed down? | The bulb is visible from the street. Shield and aim it down 23. |
| 4. Choose warm light | Is it warm white or amber? | The bulb is cool white. Choose 2,700K or below 13. |
| 5. Use the minimum | Is it brighter than the task needs? | It is far brighter than the gate needs. McDonald says over 1,000 lumens is usually not necessary 3. |
| 6. Choose efficient lights | Is it an efficient lamp? | It is an old, hot bulb. Swap for an efficient LED of the right color 2. |
McDonald Observatory adds a fix for a typical wall floodlight: a shielded PAR38-size fixture with an undersized PAR20 bulb, tilted down 3.
Where the term shows up: design drawings, bids and HOA rules
You see the term on a landscape design plan as a fixture schedule, on a bid as a line for a transformer and fixtures, and in HOA rules about brightness and color. It also appears in dark-sky ordinances.
Landscape lighting often joins other work. A path through a bed, steps on a slope or a wall beside a patio may call for lights.
The landscape design service shows where a lighting plan fits, and the patios and walkways page covers the surfaces the lights serve. A pergola that carries lights may need electrical permits. HyreYard does not install lighting.
What it does well, and where it falls short
What it can do
Limits: weather, plants and neighbors
Solar fixtures depend on daylight. They need sun on the panel, and shade from trees or buildings reduces what a panel can store. We did not load a primary source on solar run times, so we give none. Check the maker’s data for your climate.
Plants grow. A fixture that lit a shrub in spring can end up buried by summer.
Iowa State says to check the cable at least once a year for damage and to clear dirt and leaves from fixtures 4.
Replace burnt-out lamps promptly, since a failed lamp changes the load on the rest 4.
Light also crosses fences. The Park Service says light emitted just above horizontal is most likely to cause light pollution, which is why shielding matters 1. The Observatory says to keep the bulb out of view from off the property 3.
What drives the bid
We do not publish prices. A lighting bid moves with the number of fixtures, their material and type, how long the cable runs are, transformer size, the controls, and trenching or digging through hardscape.
It also depends on whether a covered GFCI outlet already exists. If it does not, Toro’s and Ring’s manuals say to contact a qualified electrician 56. That adds electrical work to the job.
Lifespan depends on the fixture, the lamp, the weather and the upkeep, so we give none. Ask what the warranty covers and whether lamps are replaceable. Use the landscaping estimates guide to compare line items, and see the cost guide for what moves a quote.
How a lighting project usually runs
A homeowner can plan and, for solar or a plug-in low-voltage kit, install. A contractor or electrician handles anything beyond a plug-in kit. The order is general.
- Decide the jobs first. Name what each light is for: a step, a path, a tree, a gate. The National Park Service starts with “is it needed?” 1.
- Choose the power type. Plug-in low voltage, solar, or line voltage through an electrician.
- Check the rules. Look at HOA covenants and local lighting ordinances. See the HOA preemption research.
- Mark utilities. Call 811 before digging a cable trench.
- Place the transformer and run the cable as the product manual says. Do not use an extension cord 567.
- Aim and test at night. Shield bulbs, check glare from the street and set the timer.
Keep power and water apart
Toro, Ring and Volt manuals say to keep the power unit at least 5 feet from a pool or spa, and Toro and Volt say 10 feet from a fountain 57.
Ring says not to mount its power supply or lights within 10 feet of a pool, spa or fountain 6. Follow your own product’s manual and call an electrician for anything near water.
Keeping the system working
- Check cables each year for damage, as Iowa State advises 4.
- Clear fixtures of dirt, leaves and debris 4.
- Replace dead lamps right away 4.
- Trim plants that block or shade a fixture.
- Re-aim lights after plants grow or a storm. Keep the bulb out of view from off the lot 3.
- Review timers when seasons change.
Warning signs, and when to call an electrician
- A tripping GFCI or an outlet cover that will not close on the cord.
- A hot, humming or damaged transformer.
- Cut or exposed cable, especially after digging or edging.
- Lights that flicker or dim along the run.
- Any fixture near a pool, spa or fountain 5.
- Any plan to add a new outlet or line-voltage circuit.
Turn off the power and call a licensed electrician for any of these. Do not repair live wiring.
Codes, standards and local lighting rules
No federal rule sets how a home yard may be lit. Two kinds of rules do apply.
The first is the electrical code your city or county adopts, which is usually a version of the National Electrical Code. We did not read the NEC for this page, and editions and local amendments differ.
The Toro manual says the suitability of its transformer within a lighting system “shall be determined by local inspection authorities having jurisdiction” 5.
The second is local lighting rules. McDonald Observatory says seven counties in Far West Texas are required by state law to have lighting ordinances, that ordinances often grandfather old fixtures for about five years, and that new or replacement fixtures must comply now 3.
That is one region’s rule, not a national one. Ask your city, county and HOA.
Product instructions bind in a third way. Manufacturer warnings are written for the listed product, and using it differently can void the listing. Follow the manual.
Landscape lighting compared with related terms
| Term | What it is | Difference |
|---|---|---|
| Landscape lighting | Fixtures that light a yard for use and appearance | The whole category |
| Low-voltage lighting | A transformer-fed system at 12 to 15 volts 5 | One power type; see low-voltage landscape lighting |
| Security lighting | Bright, often motion-triggered lights | Aims at detection, not appearance; the same shielding and color advice can apply |
| String or festoon lights | Plug-in decorative strings | Seasonal and temporary; not a designed system |
| Hardscape lighting | Lights built into steps and walls | Part of the structure; see retaining walls |
Lighting myths
- Myth Brighter is safer.
- Reality The National Park Service says more light does not guarantee safety and can reduce visibility 1.
- Myth Low voltage needs no care.
- Reality Manuals still require GFCI protection and ban extension cords 567.
- Myth Cool white is cleaner light.
- Reality The National Park Service says LEDs above 2,700K emit more blue light that can cause glare and affect wildlife 1.
- Myth A kit’s wattage is a guide, not a limit.
- Reality Each transformer has a maximum load; Ring’s example is 200 watts 6.
Dark-sky ordinances differ by place
The regional variable is the local lighting ordinance. McDonald Observatory describes Far West Texas counties that must have ordinances by state law, with grandfathering that often runs about five years and enforcement that usually starts with a complaint and a chance to fix the problem 3.
Other states have no such law. Your city, county and HOA decide. For HOA limits, see the research page below.
Choosing a type, and the next step
Choose solar for a few accent points in a sunny spot where wiring is not practical. Choose low voltage for paths and beds where you want steady light and control. Choose line voltage only with an electrician and a permit where required.
The next step is to list what each light is for, then ask your city and HOA about limits. Compare bidders with how to choose a landscaping company and read how we vet for what HyreYard checks. Questions on landscape work are answered in our FAQ.
- If A few accent lights in a sunny spot
- Then Solar may fit; confirm run time with the maker
- If New circuit, junction box or fixtures on house power
- Then Line voltage: electrician and permit 5
Questions about Landscape Lighting
What are the main types of landscape lighting?
Low voltage, solar and line voltage. Low voltage uses a transformer that steps 120-volt household power down to about 12 volts. Solar fixtures have a panel and battery and need no wiring. Line voltage runs on house power and needs an electrician. Most yard projects use low voltage or solar.
Can I install landscape lighting myself?
Plug-in low-voltage and solar kits are common homeowner projects if you follow the manual. Line-voltage wiring is not. Toro’s transformer manual says to consult a qualified electrician and local codes before installing any electrical product. Use a covered GFCI outlet and never an extension cord.
Do landscape lights need a GFCI outlet?
Yes for low-voltage transformers. Toro, Ring and Volt manuals say to connect to a covered, weatherproof receptacle protected by a Class A GFCI, with an in-use cover. If the yard has none, contact a qualified electrician. Do not run an extension cord to the transformer.
What color temperature is best for outdoor lights?
Warm light, 2,700K or below. McDonald Observatory and the National Park Service both give 2,700K as the ceiling, and the Park Service says 2,200K or amber may suit sensitive places. LEDs above 2,700K emit more blue light that adds glare and sky glow.
How bright should yard lights be?
Less than most people expect. McDonald Observatory says it is usually not necessary to exceed 1,000 lumens per bulb for outdoor residential use, and about 500 is typically enough. A shielded fixture can use less. The Park Service says more light does not guarantee safety.
What makes lighting dark-sky friendly?
Shielding, aim and restraint. The National Park Service’s steps are to light only if, when and where needed, shield and direct down, choose warm light, use the minimum and choose efficient lamps. The bulb should not be visible from off the property.
Do solar landscape lights work in winter or shade?
Less well. Solar fixtures depend on sun on the panel, so shade and short winter days reduce what they store. We did not load a primary source with run-time figures, so we give none. Check the maker’s data and place panels in the sunniest spot.
How far should a transformer be from a pool?
Follow your manual. Toro and Volt say at least 5 feet from a pool or spa and 10 feet from a fountain. Ring says not to mount its power supply or lights within 10 feet of a pool, spa or fountain. Water raises the shock risk, so call an electrician for work near it.
Can my HOA limit landscape lighting?
Often yes. Many covenants set brightness, color or fixture rules, and some cities have lighting ordinances. State law may limit what an HOA can restrict in landscaping. Read your covenants and our HOA preemption research, and ask the board before you buy fixtures.
Does landscape lighting need a permit?
Plug-in low voltage often does not, but local rules differ. New outlets, circuits and line-voltage wiring usually do. The Toro manual says suitability of its transformer in a system is decided by local inspection authorities. Ask your building department before work starts.
