Outdoor Low Voltage Landscape Lighting


Low voltage landscape lighting has become a popular choice for homeowners wanting to enhance the beauty of their homes and gardens at night. According to recent statistics, there has been a 7% increase in the use of low voltage lighting in outdoor spaces over the last five years. This surge is attributed to factors such as energy efficiency, safety, and the versatile design possibilities that low voltage lighting offers. With this post, you will be able to gain a thorough understanding of low voltage landscape lighting: how it works, its advantages and disadvantages, as well as different design considerations.

Understanding Low Voltage Landscape Lighting

In essence, low voltage landscape lighting involves a system that uses a transformer to reduce the standard 120-volt household current to a safer 12 volts. This reduction is significant because it makes the electrical fixtures safer to handle during installation and maintenance. This type of lighting is typically used outdoors for highlighting architectural features and landscaping details. It is also commonly used along walkways and stairs for increased safety and security.

Unlike high voltage or line voltage systems that require deeper burial of cable and more protective encasement due to their danger, the lower risk involved with low voltage systems means cables can be buried just below the surface or even left above ground. The lower voltages also afford an opportunity for do-it-yourself installations by homeowners who have basic electrical skills.

The Advantages of Low Voltage Landscape Lighting

Low voltage landscape lighting does not only provide dramatic effects that highlight the beauty of your outdoor spaces but also offers several other advantages.

Energy Efficiency

With energy conservation being a pressing issue worldwide, low voltage landscape lights provide an energy-efficient solution for outdoor illumination. These lights use less electricity than high-voltage fixtures, which can lead to significant reductions in electricity bills over time. As such, they are an attractive option for environmentally conscious homeowners who want to reduce their carbon footprint without compromising on the aesthetic appeal of their properties.


Another significant advantage of low voltage landscape lighting is its inherent safety. The reduced electrical shock risk makes it safer to install and maintain. This is particularly important in outdoor spaces where fixtures may be exposed to elements such as water, which could increase the risk of electrical shocks with high-voltage systems.

Versatility and Creativity

A further benefit of low voltage lighting is its remarkable versatility. There is a wide variety of low voltage lighting fixtures available on the market, each designed to fulfill a specific lighting need. Some examples include spotlights for highlighting architectural features, pathway lights for illuminating walkways, and underwater lights for enhancing water features. With such a rich variety of options, you can explore your creativity and design a unique outdoor lighting setup that matches your personal style and meets your functional needs.

The Disadvantages of Low Voltage Landscape Lighting

While the benefits of low voltage landscape lighting are plentiful, it is also crucial to acknowledge its limitations.

Lesser Light Output

One such limitation is that low voltage lights typically produce less light than their high voltage counterparts. While this might not be an issue in many applications, it could be a challenge if you require large-scale illumination. It might require more fixtures to achieve the same light levels as high-voltage systems, which could result in increased costs.

Need for Transformers

The necessity for transformers is another drawback of low voltage landscape lighting. The transformer converts the standard 120-volt household current into a lower 12-volt current that the low voltage lights can use. While this makes the lights safer, it also means that installations require an additional component – the transformer – which can add to the initial cost of the system.

Low Voltage lightingDesigning with Low Voltage Landscape Lighting

When it comes to designing with low voltage landscape lighting, there are several factors that you need to consider. These include the type of lighting fixtures that will best suit your spaces, the layout of the fixtures for optimal illumination and aesthetic appeal, as well as the overall scale of your lighting project.

In terms of fixture type, the choice will depend on both functional and aesthetic considerations. For example, if you want to highlight a specific architectural feature or plant in your garden, a spotlight would be an ideal choice. On the other hand, if you want to create a serene ambiance around a seating area, softer ambient lighting might be more suitable.

The layout of fixtures is another crucial element in low voltage landscape lighting design. Careful planning is necessary to ensure each fixture is appropriately positioned for optimal illumination and minimal light pollution. This involves considerations such as the distance between fixtures, their angle and height, as well as their proximity to elements in your landscape.

Finally, the scale of your project will determine aspects such as the number of fixtures you need, the capacity of the transformer required, and the overall cost of your low voltage landscape lighting system. While smaller projects might be manageable for do-it-yourself enthusiasts with basic electrical skills, larger projects might require professional installation due to their complexity.
