Low-voltage landscape wiring is the perfect solution when you are looking for an easy-to-install safe lighting option for all your outdoor spaces. But what is low-voltage landscape wiring and why is it such a good solution for outdoor lighting? In this buying guide, we answer those questions so you can decorate your outdoor spaces in the “bright” direction.
Low-voltage landscaping wiring is wired into a transformer where it is then converted from 120-volt power to a much lower voltage, most commonly to around 12 volts. Wires stretch out from on top or under the ground from the transformer to connect to the light fixtures. This makes low-voltage wiring an inexpensive solution to outdoor lighting, as bulbs and fixtures are cheaper to purchase since you are dealing with lower voltage.
Low voltage is the key to its safety for outdoor spaces, even in wet conditions such as placement around ponds, pools, and fountains. While most low-voltage landscape wire is measured by the same safety standards, such as UL certification, there are some additional features to look for when searching for the best quality and brand.
The insulation of low-voltage landscaping wiring is extremely important as it protects the wire within from moisture and corrosion. The most commonly used materials are resistant to moisture and able to endure harsh weather, inground installation, and abrasion. Look for tough insulation materials such as polyvinyl chloride (PVC) or other materials rated for all-weather protection.
Low-voltage landscape wiring is available in several gauges. A lower gauge number means a thicker wire and a better ability to carry power from longer distances. The most common sizes used in low-voltage landscape wiring are between 10 and 16 gauge. For a general guide, you can run approximately 100 feet of 14 to 16-gauge landscape wiring before experiencing any voltage drop significant enough to impact the lighting quality. If you plan to do runs over 150 feet, you may get better quality lighting using 10 to 12-gauge wire.
As you consider wiring options, be sure to check the requirements specific to your outdoor project design. This way, you’ll invest in a gauge size that’s enough to support power for all of the fixtures.
Low-voltage landscape wiring should come with temperature ratings to indicate what heat or cold weather they can handle before diminished performance or failing completely. This can be particularly important if you live in climates that see extreme cold or hot temperatures. When considering wiring options, be sure to check if the temperature rating is sufficient for your particular weather patterns.
While low-voltage landscape wire is made for outdoor use, not all weatherproofing methods are equal. If the wire will not be placed in the ground, UV protection is essential. UV rays from direct sunlight can damage unprotected wires, resulting in poor performance, cracking, and increased maintenance costs. UV-protected wires are usually thicker and treated with UV protection, making them much more durable for outdoor lighting spaces frequently exposed to direct sunlight.
Any wiring placed outside should be weatherproof to protect against the elements. Look for landscape wire that can withstand wind, rain, snow, dust, dirt, mud, and other outdoor occurrences that could cause potential damage. Weatherproof landscape wiring will keep your outdoor lighting functional in every season and will prevent corrosion from developing and shortening the life of the wire.
Striking the balance between durability and flexibility is the key to investing in a quality wire that is easy to install. Look for wiring that’s flexible enough to easily route through various terrain without becoming easily twisted or tangled.
Make sure you purchase enough wire to cover your entire project area. When considering the length, measure out how much wire you think you may need and then add an extra 10 to 15% so you can be absolutely sure you’ll have enough for your project.
Choose a color that will blend in with its surroundings to avoid detracting from your landscape’s aesthetic appeal, such as black or green. Brightly colored wires can stand out like a sore thumb against a natural setting.
Make sure the landscape wire is rated for the proper voltage to not damage your fixtures or system — this could create a hazardous situation. Be sure to check the maximum voltage capacity of the wire to ensure it will meet the required voltage of the lighting fixtures you’ll be using in your outdoor space.
Safety certifications are essential for safe wiring practices. Be sure to verify the landscape wiring you choose meets certified standards so you know the manufacturer is fully compliant with both quality and safety standards.
Most low-voltage landscape wiring manufacturers provide warranties and support resources such as installation guides, tutorials, and troubleshooting advice. Some even offer lifetime product support, so it’s worth checking to see if these services are included to further protect your investment.
Low-voltage landscape wiring is relatively easy to install and work with compared to other options for outdoor lighting systems. It is also flexible, which makes it easier to run through tight spaces or around corners without having to make extra cuts or bends in the wire.
Depending on your application, you may need specialized tools to install low-voltage landscape wiring, such as crimpers and strippers for connecting wires or a voltage tester for testing connections after installation.
The most common type of transformer used for low-voltage landscape wiring is a step-down transformer, which reduces the AC input into a lower DC output.
Yes, you can safely splice multiple wires together using appropriate connectors and end caps. Make sure to use electrical tape or a heat-shrinkable covering to ensure that all connections are secure and protected from moisture.
Low voltage landscaping wires should be buried at least 6 inches below grade to protect them from damage.
Low-voltage landscape wiring can last for up to 20 years, depending on the type of wire used and the environment in which it is installed.
