This is a list of all the parts you will need to install a landscape lighting system

These are the Three Things You Will Need

  1. Landscape lights
  2. Transformer
  3. Cables

Showcase Your Style with Lights

There are many options for lighting your outdoor space, depending on how big or small it is. Landscape lights can be categorized according to their usage, style, and type. For example, path lights are great for lighting your sidewalk while spot or flood lights make a striking accent on your trees or home. There are many options for energy-efficient LED landscape lighting, including modern or traditional designs. In-ground lights can cast a unique beam upwards from any location where they are placed.

When defining the boundaries of an outdoor pathway, it is a smart idea to set up landscape lighting.

It is important to consider what you want: Security? Safety on walkways? Ambient decorative lighting? It is simple to find the right landscape lighting for you once you have identified your goals.

Powering your System: Transformer

Low voltage transformers have a maximum wattage rating. A 150-watt transformer can provide power for a circuit that requires 150 watts. Start by drawing a sketch of your yard and how your lighting will be distributed. You’ll then have a better idea of how many lights will be used.

Each landscape light has a maximum wattage rating. This simple formula will help you choose the right transformer for your lights once you know how many you have.

  • + Add the combined wattage for all your lights to get 100. For example, 5 lights using 20 watts each (5 x 20 = 100).
  • Multiply the total by 1.5 (100×1.5 = 150).
  • = The total of the required transformer size in watts is what you will need. In our case, we used a 150-watt transformer.

Extra tips: Pad your numbers. It’s okay to give yourself more room for your lighting system. If you plan to add additional lights in the future, a transformer with a larger maximum wattage will be a good investment. LED lights are also cheaper! You can save on both your monthly electric bill and transformer prices by opting for low-wattage LEDs.

Cables: Putting it All Together

You will need enough wire to connect the transformer to your outdoor lighting.

Lay out all cables and components. Make sure you have enough cable to reach each light so that you can easily reposition them if necessary. Find an outlet near your lighting needs to save money on cable. It is also a good idea to run your cables along a ground line and then place them behind plants or lightly cover them with dirt or mulch. This will make it easier to adjust them as needed.

It is easy to connect outdoor lighting by plugging in a cord to an existing outlet. Connect all cables to the transformer and plug it in. Additional tip: Check your lighting placement right at night to fine-tune it. With just enough daylight remaining, you’ll be able to see how things will look at night.
