Landscape lighting installation
Most landscape lighting is low voltage. The electrician’s job is the safe power source and any line-voltage fixtures.

The short answer
Landscape lighting installation usually means a low-voltage system: a listed transformer plugged into a GFCI-protected outdoor outlet, cable buried shallowly to fixtures, and a timer or photocell. A licensed electrician installs the outdoor outlet or a hardwired transformer, and any line-voltage fixtures, which follow full outdoor wiring rules.
Low voltage vs line voltage
Low-voltage systems are safer to handle and flexible. Line-voltage fixtures give more light but need buried cable or conduit at code depths, weatherproof boxes and GFCI protection.
Transformer size is the sum of fixture wattage with headroom. Long runs need heavier cable for voltage drop.
What the job includes
A GFCI outdoor outlet with in-use cover, the transformer, cable runs, fixtures and controls.
Call 811 before digging.
Permit, time and what changes the price
A new outdoor outlet usually needs a permit; plug-in low-voltage systems often do not.
Price drivers: fixture count and type, transformer, trenching, line-voltage work. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Planning
Light paths, steps and entries first for safety, then accents. Avoid glare into neighbors’ windows.

Transformer sizing and voltage drop
Add up the wattage of every fixture and choose a transformer with headroom; many installers aim to load it to around 80% so it runs cool. Long cable runs lose voltage, so the farthest lights look dimmer unless the cable is heavier or the run is split.
Multi-tap transformers let installers raise voltage on long runs. The voltage drop calculator shows how wire size and distance affect it.
Timers, photocells and smart transformers control when lights run. Smart models need Wi-Fi coverage at the transformer location.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
This page is general information, not a diagnosis or a quote. Code rules vary by the NEC edition your state or city adopted and its local amendments.
