Low-voltage landscape lighting is an easy and cost-effective way to enhance your home’s after-dark curb appeal, safety, and security. This system uses 12-volt electrical wires for added safety—an effortless project for homeowners! However, we highly recommend hiring a professional landscape company to install a low-voltage lighting system. But you should also have some idea of the procedure.
Choose the Best Fixtures & Products
Low-voltage landscape lighting is an easy and attractive way to add illumination after dark. It highlights pathways, trees, shrubs, and key landscaping features without producing harsh glare. However, selecting and installing just the right fixtures and bulbs may prove challenging.
Transformers are essential in providing each lighting fixture with safe voltage. Each has a maximum wattage rating that must not be exceeded, or your lights may dim or cease working altogether. For maximum security, add features like light sensors and flood lights. You need these fixtures for a budget friendly garden light design.
When selecting a transformer, placing it as close as possible to your lights to minimize voltage drop due to long wire runs and simplify installation with corrosion-proof wire connectors is ideal.
Determine the Location to Install the Lights
Decide where you would like your lighting installed by walking around and marking each possible location with flags or pencils, then measuring their distance apart to calculate how many wires will be necessary to reach your transformer.
Select the wattage for your lighting based on what it will illuminate (tighter beam spreads provide intense lighting, while wider ones illuminate more of an area). Don’t exceed your transformer’s power rating or your lights may become dim or won’t turn on at all!
For instance, when installing path lights, a transformer capable of managing at least 300 watts will be necessary.
Choose the Wire For a Strong Connection
As you design your lighting layout, determine what kind and length of connecting wires will be necessary to connect all the fixtures. Most low-voltage light fixtures come equipped with connectors to make this process simple. Additionally, consider whether conduit will be necessary if wire routes cross walkways, driveways, or hardscapes.
Most landscape lights require a transformer that “steps down” household current from 120V to 12V for easier and safer lighting options than line voltage landscape lighting. There are several garden issues that occur just because of poor quality material and maintenance.
One installation technique often used involves connecting one light fixture directly to a transformer, followed by each additional fixture connected in a daisy chain fashion. Unfortunately, this approach may cause voltage drops as fixtures move further from the transformer, leading to dimmer light output.
Install the High-Quality Transformer
Transformers are an essential component for powering landscape lighting systems. They convert standard household line voltage (120 V) to 12 V for safe operation and ensure that lighting remains on.
Calculate the total wattage of your light fixtures before choosing a transformer with enough capacity to support them. Refer to the transformer’s manual for the recommended low voltage wire gauge (which may differ by brand).
Install the low-voltage electrical cable along your path of lights according to the directions in the transformer’s manual, at least 10 feet from each fixture.
Hold the transformer at ground level using stakes and strip away about 1/2 inch of insulation from both conductors before connecting them to their terminal screws in the transformer. Before burying, test all lighting and electrical connections by turning on your transformer.
Installing Landscape Lighting
Professional outdoor lighting installation can save time and money. However, learning to splice wire and install a transformer on your own can be challenging, and even the most dedicated professionals may not be up for the task.
Once the cable is laid out, use wire strippers to strip about an inch of insulation off both ends of each wire before attaching each light fixture using silicon twist-on connectors.
Low-voltage transformers often include built-in timers to make switching on and off your lights easier. Otherwise, adding a photocell or astronomical timer can reduce the voltage drop and thus lessen its effects on landscape lighting performance and energy costs.
Connect the Wires to the Lights
Plan out your lighting layout ahead of time to determine what types and lengths of connecting wires you will require—this can ensure everything runs smoothly during installation.
Landscape lights must typically be connected to a transformer rated to meet their respective light loads. For instance, installing six pathway lights that each require 50 watts requires a transformer with 300-watt or greater capacity.
Voltage loss should not be a major concern when wiring lights up under 100 feet long, depending on their thickness (gauge). For longer runs, consider using a brass butt-splice connector piercing through insulation to connect conductors.
Plug in the Lights
Illuminating walkways, steps, and driveways provide extra protection at night while simultaneously improving your landscape and welcoming guests with an engaging ambiance that makes your home an inviting space all day long.
Start by laying out and installing the transformer. Use the wattage rating of your light fixtures to determine how much wire is necessary—for optimal results, try staying 20 percent below their maximum wattage rating.
Frequently Asked Questions
Here are some questions that our readers have asked us
How do you trench low voltage lighting?
Dig a 4-6-inch deep trench along your planned layout to trench low-voltage lighting. Lay the wire in the trench, optionally using a conduit for protection. Connect the fixtures to the wire, test the system, and then cover the wire with soil. Ensure everything works before fully burying the trench.
How deep do you bury low voltage lighting?
Bury landscape lighting low-voltage wires 4 to 6 inches deep. This depth protects from lawn equipment, foot traffic, and weather while allowing easy access for future adjustments or repairs.
Conclusion
Installing low-voltage landscape lighting with light sensors is a straightforward and rewarding project that can transform the look and safety of your home’s exterior. With the right approach, you can enjoy a beautifully illuminated landscape that enhances your home’s curb appeal and security for years to come.
