Path Light Symbol
Definition: The Path Light symbol represents a low-voltage landscape luminaire installed along walkways, garden paths, or driveways — used in landscape and exterior wiring diagrams to indicate a stake-mounted or ground-level light fixture connected to a low-voltage landscape lighting system (typically 12 V AC from a transformer), with a positive (+) and negative (−) supply, per NEC Article 411 and IEC 60364-7-714.
Also known as: walkway light, garden path light, landscape path light, low-voltage garden light, stake light, bollard light.
What the Path Light symbol means
The Path Light symbol represents a small exterior luminaire on a stake or low post designed to illuminate pedestrian walkways, garden borders, and driveways at night. Path lights are almost universally operated from a low-voltage landscape lighting transformer (12 V AC, 150–600 VA) fed from a GFCI-protected 120 V AC outlet, making them safe to handle and install without high-voltage electrical qualifications in most jurisdictions.
In landscape wiring diagrams and site electrical plans, the path light symbol indicates the position of each fixture along a pathway. Multiple path light symbols are connected in parallel on a low-voltage cable run from the transformer. The positive (+) and negative (−) terminals of each symbol represent the two conductors of the 12 V AC supply wire (typically 16/2 or 12/2 low-voltage cable) that loops from fixture to fixture before returning to the transformer.
How to identify the Path Light symbol
The Path Light symbol is drawn as a small vertical stake line topped with a circular or mushroom-shaped lamp head. On site plan wiring drawings, the symbol may appear as a stylised lantern on a short post (shorter than an outdoor lamp post symbol to indicate low-mounting height). Two connection terminals at the base represent the + and − supply conductors. The path light symbol is typically smaller and more closely spaced than the outdoor lamp post symbol, reflecting the fixture's low profile (0.3–0.6 m height) and dense placement (1–2 m spacing) along walkways.
Function in a circuit
The path light provides low-level illumination along pedestrian pathways using a 12 V AC or 12 V DC LED module, halogen MR16 lamp, or integrated LED chip mounted in a weatherproof head. The 12 V AC supply from the landscape transformer is safe for direct burial cable and eliminates the shock risk associated with line-voltage outdoor wiring. Integrated photocell sensors or timer controls at the transformer switch all path lights simultaneously at dusk or on a schedule. Lumen output ranges from 30–400 lm depending on lamp type and desired illuminance level.
Standards: IEC vs ANSI
| IEC 60617 | IEC 60364-7-714 (Requirements for special installations — outdoor lighting installations) governs low-voltage landscape lighting systems in IEC regions. The path light symbol follows general IEC 60617 luminaire notation with a low-voltage annotation. IEC 60598-2-5 covers road and street luminaires including path-lighting types. |
|---|---|
| ANSI/IEEE 315 | NEC Article 411 (Lighting Systems Operating at 30 Volts or Less) governs low-voltage landscape lighting installations in North America, including path lights. NEC 410.10 requires outdoor luminaires to be listed and identified for wet or damp locations. ANSI/IEEE 315 represents path lights using the general exterior luminaire symbol with a 'low-voltage' designation on architectural electrical drawings. |
| Key difference | NEC Article 411 (North America) and IEC 60364-7-714 (IEC regions) both regulate low-voltage outdoor lighting; NEC sets the 30 V threshold for reduced-voltage lighting systems, while IEC uses SELV (Safety Extra-Low Voltage, ≤50 V AC or ≤120 V DC ripple-free) classification under IEC 61140. Schematic symbol conventions are similar in both standards. |

Typical values
System voltage: 12 V AC (transformer output) or 12 V DC (solar/LED driver). Lamp power: LED 1–8 W, halogen MR11/MR16 5–20 W. Lumen output: 30–400 lm. Cable: 16/2 or 12/2 direct-burial low-voltage landscape cable. Transformer: 150–600 VA, 12 V AC output from 120 V AC input. Maximum fixture count per transformer zone: determined by total wattage ÷ by transformer zone VA rating (not exceeding 80% loading). Fixture height: 0.3–0.6 m.
Where the Path Light symbol is used
- Garden pathway lighting: path lights along stone or paved garden walkways guiding foot traffic at night
- Driveway border lighting: path lights defining the edges of residential driveways
- Landscape bed edging: low path lights illuminating garden borders and planting beds
- Pool and water feature surrounds: path lights defining paved areas around pools (must comply with NEC 680)
- Commercial courtyard paths: path lights on hotel or office building courtyard walkways
- Stairway step illumination: low-profile path lights at the base of outdoor steps for safety lighting
Example
On a landscape electrical plan, eight path light symbols are drawn along both sides of a 15-metre garden walkway, connected in a parallel daisy-chain on a single run of 12/2 direct-burial low-voltage cable looping from a 12 V AC, 150 VA landscape transformer located at the house wall. Each path light symbol shows + and − terminals connected to the cable conductors. A photocell module on the transformer activates all eight lights at dusk automatically.
Key facts
- The Path Light symbol represents a low-voltage (12 V AC) stake-mounted landscape luminaire used to illuminate garden paths, walkways, and driveways, connected via + and − terminals to a landscape lighting transformer.
- Path lights operate on 12 V AC supplied by a low-voltage landscape transformer (NEC Article 411; IEC 60364-7-714), making the wiring safe for direct burial and installation without high-voltage qualifications.
- Multiple path lights are wired in parallel on a daisy-chain low-voltage cable run from a central transformer; total wattage on each transformer zone must not exceed 80% of the zone's VA rating.
- NEC Article 411 governs lighting systems operating at 30 V or less in North America; IEC 60364-7-714 and the SELV provisions of IEC 61140 govern equivalent low-voltage outdoor lighting in IEC regions.
- Path light LED lamps consume 1–8 W for 30–400 lm, replacing 5–20 W halogen MR11/MR16 lamps at significantly lower energy consumption and longer lamp life (25,000–50,000 hours).
- Direct-burial landscape cable for path lights is typically 16/2 AWG (for short runs, light loads) or 12/2 AWG (for longer runs or higher loads) rated for direct soil burial at 6-inch minimum depth.
- The path light symbol has two terminals: positive (+) and negative (−), representing the two conductors of the 12 V AC supply; polarity is not critical for 12 V AC systems but is important for 12 V DC solar or LED-driver systems.
Frequently asked questions
What does the path light symbol look like in a landscape wiring diagram?
The path light symbol is drawn as a short vertical stake line topped with a circular or mushroom-shaped lamp head, with two connection terminals (+ and −) at the base. It is similar to the outdoor lamp post symbol but smaller and lower-profile, reflecting the path light's low staking height of 0.3–0.6 m compared to a full post light.
What does a path light symbol mean on an electrical plan?
The path light symbol on an electrical plan indicates the installation location of a low-voltage stake-mounted landscape light fixture connected to a 12 V AC landscape transformer circuit. The symbol tells the installer where to place each fixture and how the low-voltage supply cable routes between fixtures and back to the transformer.
What voltage do path lights use?
Most residential landscape path lights operate at 12 V AC supplied by a low-voltage landscape lighting transformer that steps down the 120 V AC (North America) or 230 V AC (IEC regions) mains supply. Some solar-powered path lights operate at 12 V DC from an integral solar panel and battery. NEC Article 411 governs systems operating at 30 V or less in North America.
What standard governs path light installation?
In North America, NEC Article 411 (Lighting Systems Operating at 30 Volts or Less) governs low-voltage landscape path light installation, including cable burial requirements and transformer listing. In IEC regions, IEC 60364-7-714 (outdoor lighting installations) and the SELV provisions of IEC 61140 apply. All outdoor path lights must be rated for wet location use per NEC 410.10 or IEC 60598-2-5.
How many path lights can I connect to one transformer?
The number of path lights per transformer zone is limited by the transformer's VA (watt) rating. The total wattage of all connected fixtures should not exceed 80% of the transformer zone capacity. For example, a 150 VA transformer zone can safely power up to 120 W of fixtures: approximately 15 path lights at 8 W each. Always check the transformer manufacturer's maximum load specification.
What cable is used for landscape path lighting?
Standard landscape path lighting uses 16/2 AWG or 12/2 AWG direct-burial low-voltage cable, typically with a black and white conductor pair in a grey or black jacket rated for direct soil burial. NEC Article 411.4 permits the use of identified low-voltage landscape cable at a minimum burial depth. 12/2 AWG is preferred for long cable runs (over 15 m) to minimise voltage drop across multiple fixtures.
