How Do Low-Voltage Landscape Lighting Systems Work?

By now, your obsessions for landscaping should have allowed you see that to highlight your favorite plants or to light a walkway during night times, a low-voltage lighting system is needed for your outdoor space. But there is one thing you haven't understood- how low-voltage lighting systems work.

Although, most companies that handle landscaping in Orlando always advocate the use of the low-voltage lighting system, most clients don’t really know what they’re getting involved with. Thus, if you read carefully, you will understand the logic behind the system- how it works.

Read on to see how landscaping firms in Orlando design and install low-voltage lighting system.


The fundamental component for distributing regulated voltage to all present landscaping lights in the yard is the transformer. Each transformer consisting of many electronic components steps the home's 120v down to 12v.

Each manufacturer designs transformers with different ratings. Thus, when considering the type of transformer to be used, you should choose one that has more watts, or power than the addition of watts your feature will make use of.

For clarity sake, select a transformer that is rated for 300 or 400 watts if the landscape lights equal 200 watts. Failure to do these will mount more load on your transformer which in turn might fail and heat up.


Wires are connected to the transformer, and in turn, it is stretched along the ground to each light fixture mounted in the house. The pattern chosen may vary from company to company. For example, some companies might decide to bury the wires up to 3 inches deep under the soil, or some will just lay it on the ground. Since there is low voltage running through the wires, the risk of electric shock is eradicated.

Timers and Photocells

To save the cost of electricity one might incur, it is advisable to attach a photocell to your transformer so that light will automatically come on at sunset and go off during sunrise. Alternatively, you can use a timer and set it as desired, that is, as the lights come on and go off when you wish it to. Photocell takes advantage of the ambient light and automatically turns the system on when the sun sets.

Both the photocells and timers use a switching system to hinder and provide power when the transformer needs it.

Light Fixtures and Bulb

Most practitioners of landscaping in Orlando place light fixtures 10 feet from the transformer and each other. This is due to the versatility of low-voltage lighting. It is more straightforward and simpler to mix any fixture types you desire along the same transformer line, from walkway lights to patio wall lights.

Most designers calculate each bulb's wattage on one line to make sure the power rating does no go beyond the ability the transformer can retain. Never place 200-watt bulbs on a 600-watt rated transformer, else you risk having a dim light and it might not even work at all.
