Warmer temperatures indicate that Spring has arrived and patio season is right around the corner. With the ground softening up, Spring is often considered the perfect season to make changes to your patio. When it comes to patio design, there are endless possibilities when it comes to landscape lighting. However, a crucial component of any patio design is a landscape lighting transformer.
Never heard of a landscape lighting transformer before? No need to worry. The expert technicians at AJ’s Electrical have put together a guide of the five things to know about landscape lighting transformers to ensure that your backyard oasis is ready in time for summer.
What is a Landscape Lighting Transformer?
The first thing you need to know is what a landscape lighting transformer actually is. This device is used to step down high input electric current to output electric current. It is designed for landscape lighting consumption, hence the name Landscape Lighting Transformer. This transformer can convert high levels of voltage, such as 120 volts, to very low levels, such as 15 volts.
A lighting transformer is typically an autotransformer, which means that this type of transformer only contains one winding.
Lighting transformers on the other hand, are transformers that are used to work lighting. They are designed to make it possible to transform voltage down to levels that are suitable for household lighting.
Why Do I Need a Landscape Lighting Transformer?
Now that you know what a landscape lighting transformer is, let’s talk about why you need it. The main reason would be so that your landscape lighting can function properly and consistently. When it comes to household electricity, most lights require an input of anywhere from 120 to 200 volts. However, in the case of landscape lighting most lights require a lot less volage. Outdoor lighting, particularly garden lighting, only requires around 12-15 volts to run.
A landscape lighting transformer is a critical component to ensure that your landscape lighting receives the correct amount of power to run efficiently.
Where Should I Put my Landscape Lighting Transformer?
While you may want to tuck your transformer away to avoid ruining your backyard aesthetic, here are some things to consider when choosing a spot to place your device:
- Transformers should be placed in a well-ventilated spot in the backyard, away from any direct irrigation spray – this is an electric device after all.
- They should also be located somewhere central to the majority of lighting fixtures as you don’t want too many cables running from your transformer throughout your backyard.
- It is recommended that transformers be at least 10 feet away from your home, to minimize any potential fire hazard it may pose to your home.
Now that you understand what a transformer is and where to place it, it’s time to determine which one is right for you. So how do you pick the right transformer? Here is how to determine what size transformer you’ll need:
Light Fixtures and Total Wattage
Taking into consideration the designs for your backyard, determine the number of light fixtures that you’ll have and what the total wattage for these fixtures will be. For example, if you have six landscape spotlights and one set of string lights that each have a maximum wattage of 7 watts each, to be paired with six path lights that only require 5 watts each, your outdoor setting requires a total wattage of 72.
Now keeping in mind that it’s recommended that a transformer only run 80% of its maximum capacity, that means that you’ll need a transformer that is capable of at least 88 watts.
With that being said, you also have to keep in mind any future additions you may include in your backyard space. That should offer a clear estimate of the size of the transformer you require.
How Long Do Transformers Last?
On average, if properly handled and maintained a standard low-voltage landscape transformer should have a solid 20 to 25 years. While they may last longer with better care, there is a risk that the transformer loses efficiency after its expected lifespan.
Once you have your patio upgrades picked out, all that’s left is to install the transformer. While you can attempt to install the transformer yourself, it’s recommended to consult an experienced electrician to help you out with these final steps. Their expertise will help guide you through any questions or concerns you may have and leave you with a piece of mind when it comes to electrical safety.
