In this blog post, I cover the best smart landscape lighting transformers you can get for your outdoor lights this year.
Transform Your Outdoor Lights
As a smart home enthusiast and longtime homeowner, I’ve learned that no outdoor lighting setup works reliably without a quality transformer.
These low-voltage transformers (also known as wifi landscape lighting transformers) step 120v down to safe, low voltage, preventing voltage drop and keeping illumination even across fixtures.
Don’t confuse them with controllers — controllers manage schedules and automation, while the transformer supplies the power. Smart models add connectivity and control, matching the smart lighting trend in this report from MarketsandMarkets.
I’ve personally used the first three on this list; the rest were chosen on top ratings, professional reviews, and research.
Below are the best smart landscape lighting transformers for performance and reliability.

Best Smart Landscape Lighting Transformers FAQ
1) How can I tell how much wattage I need?
To determine the wattage you need, add up the wattage of all lights you plan to connect. For optimal performance and safety, choose a transformer with a wattage capacity 20-30% higher than your total. For example, if your landscape lights total 150W, a 200W transformer would provide enough power with room for future additions.
Here is a pin I put together to help you calculate the wattage. Feel free to share it to Pinterest to save it for later.
2) What’s the difference between the best smart landscape lighting transformers and controllers?
The best smart landscape lighting transformers reduce line voltage from 120V AC to safer levels, like 12V or 15V, making it ideal for outdoor lighting systems. Controllers, meanwhile, manage schedules and brightness but don’t alter voltage. For more on the importance of transformers, see this guide from LED Light Expert.
