Landscape Light (Low Voltage) Symbol
Definition: The Landscape Light (Low Voltage) symbol represents a low-voltage outdoor luminaire in wiring diagrams, typically a 12 V AC/DC pathway, accent, or spot light, drawn as a labeled fixture block with positive (+) and negative (−) supply pins, used in residential and commercial landscape wiring diagrams to indicate fixtures on a low-voltage transformer distribution cable, governed by NEC Article 411 and ANSI Y32.2 / IEEE 315 lighting symbol conventions.
Also known as: low voltage landscape light, 12V path light, garden light, outdoor accent light, landscape fixture, LV landscape luminaire.
What the Landscape Light (Low Voltage) symbol means
The Landscape Light (Low Voltage) symbol denotes a class 2 (low-voltage, limited energy) outdoor luminaire operating at 12 V AC supplied by a listed low-voltage landscape lighting transformer. In site and residential electrical wiring diagrams it marks each fixture location on a cable run, showing the distribution of 12 V power from a transformer to individual lights.
The two pins + (positive) and − (negative) represent the two-conductor low-voltage supply cable connections. NEC Article 411 classifies low-voltage landscape lighting as a class 2 circuit (≤30 V AC, ≤42.4 V peak), exempting the wiring from conduit requirements when using listed class 2 cable and transformers. The symbol communicates fixture placement, load contribution, and circuit continuity on the landscape lighting plan.
How to identify the Landscape Light (Low Voltage) symbol
The Landscape Light (Low Voltage) symbol is drawn as a small stylised luminaire — typically a light-bulb outline, a lantern silhouette, or a staked fixture shape — with two pins at the base: + (positive, left) and − (negative, right). The symbol may be labeled 'LL', 'LV LIGHT', or '12V' to distinguish it from line-voltage outdoor fixtures. On site plans it appears at the scaled fixture location, connected to a cable run line representing the 12 V two-conductor landscape wire.
Function and usage boundary
A low-voltage landscape light converts 12 V AC or DC electrical energy from the landscape transformer into light, typically using an LED lamp (modern) or halogen/incandescent bulb (legacy). The fixture is a load on the secondary winding of the step-down transformer; multiple fixtures are connected in daisy-chain or home-run configurations along the 12 V cable. The + and − terminals connect directly to the two conductors of the landscape cable, with no requirement for neutral or earth ground at the fixture per NEC Article 411.
Standards: IEC vs ANSI
| IEC 60617 | IEC 60598-2-5 (luminaires — particular requirements: floodlights) and IEC 60364-7-714 (electrical installations of buildings — requirements for external lighting installations) govern low-voltage outdoor luminaires. IEC 61558-2-6 specifies safety isolating transformers for low-voltage landscape lighting systems. |
|---|---|
| ANSI/IEEE 315 | NEC Article 411 (Low-Voltage Lighting) governs landscape lighting systems ≤30 V AC in North America, requiring listed transformers and class 2 cable. UL 1838 lists low-voltage landscape lighting systems. ANSI Y32.2 / IEEE 315 use lighting fixture symbols for schematic and site-plan representation. |
| Key difference | NEC Article 411 and IEC 60364-7-714 both exempt low-voltage landscape wiring from conduit requirements, but NEC uses the class 2 circuit classification (≤30 V, ≤100 VA) while IEC uses SELV (Safety Extra-Low Voltage, ≤50 V AC, ≤120 V DC) circuit classification. The schematic symbol conventions per ANSI Y32.2 and IEC 60617 are both labeled fixture blocks. |

Where the Landscape Light (Low Voltage) symbol is used
- Residential pathway and driveway edge lighting for safety and aesthetics along walkways
- Garden accent lighting to highlight trees, shrubs, and architectural features at night
- Deck and step lighting for safety illumination of level changes in outdoor living areas
- Pool and water feature accent lighting using listed wet-location 12 V fixtures
- Commercial property landscape and parking lot perimeter accent lighting
- Holiday and seasonal decorative lighting systems using 12 V LED strings on class 2 transformers
Key facts
- The Landscape Light (Low Voltage) symbol represents a 12 V class 2 outdoor luminaire with two pins: + (positive) and − (negative), connecting to the two-conductor low-voltage landscape cable.
- Low-voltage landscape lighting systems operate at 12 V AC supplied by a listed step-down transformer; NEC Article 411 classifies these as class 2 circuits (≤30 V, ≤100 VA per output) exempt from conduit requirements.
- Modern landscape lights use LED lamps (1–20 W) replacing legacy halogen bulbs (20–50 W); LED conversions reduce transformer loading by 60–80%, often allowing more fixtures on the same cable run.
- Voltage drop is the primary design constraint: 12 AWG class 2 cable has 1.588 Ω per 100 m; at 2 A load the drop is 0.32 V per 10 m, limiting long runs to the transformer's highest voltage tap or requiring home-run wiring.
- Most landscape transformers include 12/13/14/15 V taps or automatic voltage compensation to counteract cable voltage drop for fixtures distant from the transformer.
- IEC 60364-7-714 and IEC 61558-2-6 govern low-voltage outdoor lighting and safety isolating transformers in IEC-standard (international) installations; NEC Article 411 and UL 1838 govern North American installations.
- All low-voltage landscape wiring must use listed class 2 direct-burial cable; conductors must be buried at least 150 mm (6 inches) deep per NEC 411.4 to protect against accidental damage.
Frequently asked questions
What does the Landscape Light (Low Voltage) symbol mean in a wiring diagram?
The Landscape Light (Low Voltage) symbol represents a 12 V outdoor fixture that is powered from a class 2 low-voltage landscape lighting transformer. It marks a luminaire location on a site plan or wiring diagram, with + and − pins indicating the polarity of the two-conductor 12 V cable connection.
What does the landscape light symbol look like?
The landscape light symbol is a small stylised luminaire — a light-bulb shape, lantern outline, or stake-and-head fixture shape — with two pins at the base labeled + (positive) and − (negative). On site plans it is drawn at the fixture's installed location along the 12 V cable run line, often labeled '12V', 'LL', or 'LV LIGHT'.
What voltage do low-voltage landscape lights use?
Standard low-voltage landscape lights operate at 12 V AC, supplied by a class 2 step-down transformer connected to the 120 V (North America) or 230 V (IEC regions) mains. NEC Article 411 permits any voltage ≤30 V AC for class 2 landscape lighting; in practice 12 V AC is the near-universal standard. Some modern LED landscape systems use 24 V DC for reduced voltage drop over longer runs.
Do low-voltage landscape lights need conduit?
No. NEC Article 411 exempts class 2 (≤30 V) landscape lighting cables from conduit requirements, provided listed two-conductor direct-burial class 2 cable is used and buried at least 150 mm (6 inches) deep. Conduit is required where cable runs under driveways, through walls, or in areas of mechanical damage risk, per NEC 411.4.
What standard governs low-voltage landscape lighting?
In North America, NEC Article 411 (Low-Voltage Lighting) and UL 1838 govern low-voltage landscape lighting systems. In IEC-standard regions, IEC 60364-7-714 (external lighting installations) and IEC 61558-2-6 (safety isolating transformers) apply. The schematic symbol follows ANSI Y32.2 / IEEE 315 and IEC 60617 lighting fixture conventions.
How many landscape lights can I connect to one transformer?
The number of fixtures is limited by the transformer's VA rating and cable voltage drop. For a 150 W transformer and 5 W LED fixtures, the maximum is 30 fixtures before reaching rated capacity; however, cable voltage drop typically limits a single cable run to 10–15 fixtures before the furthest fixtures receive insufficient voltage. Use the transformer's highest voltage tap, split into multiple cable runs, or use 12 AWG cable to maximise run length.
What is the designator for a landscape light fixture in a schematic?
Lighting fixtures, including low-voltage landscape lights, use the designator L (luminaire) or the prefix LT in electrical drawing conventions, numbered sequentially — L1, L2, etc. On residential site plans they are often identified by a fixture schedule number rather than an IEC 60617 or ANSI Y32.2 reference designator, since site-plan conventions differ from circuit-schematic conventions.
