What is low-voltage landscape lighting?

We all have lights inside the house that helps us get through the dark easier.

These lights use 120 volts of power in order to work. Unlike regular lights, low-voltage lights require a much lower level of energy to function.

More precisely, low voltage landscape lighting takes only 12 volts to provide light.

Due to this, setting up low voltage lighting is something anyone can do, without any previous experience.

The entire process is safe because you won’t work with dangerous electrical wires. Also, you’ll need just a few components to make it work.

Why low voltage transformer used for landscape lighting?

But you will need something to reduce the available power to just 12 volts.

This is where the transformer comes into the scene.

Getting a transformer is a must, as it is the central piece of your future low voltage landscape lighting.

You won’t be able to properly power a low voltage landscape lighting without a transformer that will provide it with an adequate level of power.
However, when choosing the transformer, you will use for your landscape lighting project, you’ll need to bear in mind the watts each light will consume.

Ad the wattage of each light or multiply the value of the wattage with the number of lights, if they are all the same, and see how much power your transformer should provide.

For example, if the sum is 300 watts, you will need a transformer capable of developing 400 or 500 watts.

This way, you make sure that all the lights will work properly when turned on.

Troubleshooting Low Voltage Landscape Lighting

Troubleshooting Low Voltage Landscape Lighting

Sometimes, no matter how careful you are to respect all the steps for installing low voltage landscape lighting, things appear to go wrong.

The lights may not turn on, in spite of the fact that everything looks alright.

Or, even if the lights turn on, they appear to be dim instead of showing all their power.

No matter what the issues appear to be, it can be frustrating to see that you can’t enjoy the results you were hoping to get.

Also, finding the issue in order to address it is not always easy. Arm yourself with patience and start checking your low-voltage system to discover the problem that may be causing the malfunctions.

01. The lights are not turning on at all

Noticing that the lights fail to turn on once you’re done installing the entire system can be very frustrating.

When it comes to this scenario, the factors that lead to it are rather numerous.

Ideally, to avoid this from happening, you should be careful how you do the installment right from the start.

If everything is set up correctly, the chance for troubleshooting scenarios to occur is reduced.

If you are experiencing this particular scenario, the first thing you need to check is to see whether the transformer is connected to a power source and if it has power.

A transformer that does not work will not allow the lights to turn on. In case you come to the conclusion that the transformer has power, but the lights still don’t work, a short maybe shut it down.

We will describe the short in detail later on.
Bear in mind that you are dealing with a circuit, so if a light doesn’t work, the entire lighting system won’t work.

So, if the transformer is properly powered, start checking the light bulbs. Check for broken filaments or lights that are not sitting right in their socket.

02. There’s a short on the circuit

There are many factors that can cause a short on circuit.

You will need to check the entire system to see whether you’re dealing with a short and if so to check what’s causing it, so you can properly repair it. What can lead to a shortage?

It can be a socket that got damaged, corroded, or exposed to water.

It can also be a wire with a cut on its surface, a wire connection that failed, portions of the system that have been exposed to too much moisture or water, or portions that got damaged as a result of rubbing against trees or rocks.

Of course, the cause of a short can be different than the mentioned examples. The main idea is that you need to find the cause and replace or repair the damaged part.

03. The lights are dim

Dim lights can be frustrating, but they can indicate a connection that is not done properly.

So, the first thing you need to do is to check if the lamp or lamps are properly connected to the socket.

If there’s any room to wiggle, the lamps will provide a dim light. You should also check the connection of the power cable. A proper connection should show pins that pierced the copper strand nicely.

Sometimes, even a detail this small can make an entire system work poorly.

Is the value of your voltage drop 2.0 volts? You should calculate this part again and make sure it does not exceed this value.

Also, check the total wattage of the system. If the value is above the recommended value, you will have to remove one or two fixtures from the circuit or use fixtures that have a lower wattage.

04. Lights are burning off at a premature rate

When you buy a certain type of light, you probably know that they have an average period in which they should function.

If the lights are burning off at a premature rate, making you replace them more often than you should, you may be dealing with system issues.

Even if you don’t buy the most expensive lights, you should still be able to use them for a good period.

If you don’t, there might be too much voltage on the cable, which leads to premature burning off of the lights.

First, check the number of functioning hours in the case of your lights.

In case you’re dealing with short-life lamps, seriously consider getting halogen lights instead.

Or drop the voltage of the affected cable by increasing the wattage load or drop the run of the cable down to the next lower voltage tap.
