Low Voltage Landscape Lighting System Components


Choose The Suitable Transformer

A transformer is a primary device that changes a 120-volt line voltage to 12 volts, suitable for lighting fixtures. Begin by determining the system’s total wattage, which should encompass the power needed for all light fixtures and devices, as indicated in the lighting diagram.

Multiply the total wattage by a safety factor of 1.25 to obtain the suggested wattage for the transformer.

For instance, if you have ten 20-watt light fixtures, your requirement is 10* 20=200 watts. Consequently, the recommended transformer power is 200* 1.25= 250W. You may opt for a transformer with an even higher power rating to guarantee sufficient power for all lighting fixtures. A higher-rated transformer generates less heat, which can indirectly extend the lifespan of electrical components. However, stay within 33% of the recommended power.

Ideally, the transformer can be installed near or within the home, such as in a garage or basement. Depending on your lighting plan, you may need multiple transformers.

Determining the right transformer size: The size of the transformer you need depends on the total wattage of your lighting system. Add up the wattage of all the light fixtures you plan to use. Select a transformer with a capacity slightly higher than the total wattage to ensure optimal performance and accommodate future expansions.

Understanding wattage and voltage requirements: Low voltage lighting systems typically operate at 12 or 24 volts, significantly lower than the standard 120 volts used in most households. Ensure your transformer’s voltage output matches the requirements of your light fixtures, and consider the wattage to prevent overloading the transformer.

Types of transformers: electronic vs. magnetic: Electronic transformers are generally smaller, lighter, and more energy-efficient than magnetic transformers but may produce more electrical noise. Magnetic transformers are more significant, heavier, and often more durable, making them suitable for larger or more complex lighting systems.

Choose the Correct Wire for Low Voltage Landscape Lighting

Types of low-voltage cables: Low-voltage landscape lighting systems use specialized lines, typically copper or aluminum, to carry low-voltage electrical currents. These cables come in various gauges (thicknesses) to accommodate different system sizes and distances.

Proper cable sizing and voltage drop: Use the appropriate gauge cable for your system to minimize voltage drop and ensure even lighting. Thicker lines (lower gauge numbers) can carry more current and are recommended for longer runs or higher-wattage systems.

The subsequent phase in setting up low-voltage outdoor lighting involves selecting wires to connect the transformer to every fixture. These wires are available in various numerical gauges and lengths.

For low-voltage outdoor lighting, you can select 10-, 12-, 14-, or 16-gauge wires, frequently used in such applications.

A more substantial wire is necessary for higher-power outdoor lighting installations, as it enables the current to travel greater distances.

For low-power projects under 200 watts, a thinner wire is more suitable.

We suggest opting for a 10- or 12-gauge wire for extended distances to avoid voltage drops. For instance, copper wire is an ideal choice for low-voltage outdoor lighting due to its lower resistance.

Take a look at this table.

Types of Wire Connectors

Many wire connectors are available, each with its specific use case. Here are some common types of wire connectors:

Twist-On Wire Connectors: These are also known as wire nuts and are among the most common types of wire connectors; they are made up of a plastic shell and a metal coil and are used to connect two or more wires by twisting them.

Crimp Connectors: These connectors create a permanent connection between wires. They consist of a metal tube crimped around the cables to make a secure connection.

Push-In Wire Connectors: These connectors are easy to use and require no twisting or crimping. Instead, they comprise a plastic shell with metal contacts that grip the wire when pushed into the connector.

Terminal Blocks: These connectors connect multiple wires neat and organized manner. They consist of a plastic block with metal terminals to which the cables can be attached.

IDC Connectors: These connectors are used to connect flat ribbon cables. They consist of a plastic shell with metal contacts that pierce the insulation of the ribbon cable to make a connection.

Butt Connectors: These connectors connect two wires end-to-end, consisting of a metal tube crimped around the cables to create a secure connection.

Solder Connectors: These connectors require a soldering iron to connect between wires permanently. They consist of a metal tube that is heated to melt the solder and create a connection between the cables.

Connection Methods

After determining the optimal low-voltage transformer, cable length, gauge, and type for your outdoor lighting project, move on to the next step. Next, pick a connection method that aligns with your lighting requirements for attaching the fixtures to the transformer.

Daisy Chain Method
As the name suggests, the daisy chain method connects all fixtures in a string of daisies, with the first connecting to the transformer. This wiring method is best suited when the fixtures are not placed in scattered groups, but the voltage will drop with distance.

The first fixture may have a voltage of 12 volts, whereas the last institution may be running on 7 volts. However, this method would be exemplary for outdoor lighting as LEDs have a low acceptable voltage range.

The t-method is similar to the daisy chain method except for the transformer that connects to the middle of the fixture chain instead of the first fixture. This wiring method saves on the amount of wire used in the outdoor lighting project.

However, use it only if you’ve already built a daisy chain but now want to save the amount of wire.

Hub Method
This wiring method connects all wire runs to a hub junction, and from there onwards, a single mainline connects to all fixtures. Moreover, it ensures equal voltage for all institutions and reduces the number of splices in the field.

The Hub method is suitable to deploy when the fixtures are in a group form and placed in a small area. However, it requires a lot more wire than other methods.
