How Far Can You Run Low Voltage Landscape Lighting: A Comprehensive Guide

When it comes to installing low voltage landscape lighting, it’s essential to understand the limitations of your wiring. A crucial guideline to keep in mind is the 100/100 rule: for every 100 watts of light you intend to use, you should limit the cable length to a maximum of 100 feet, and this cable should be 12 gauge. This rule ensures that the voltage drop along the wire doesn’t become too significant, maintaining the effectiveness of your lighting system. Additionally, remember to employ a voltmeter to regularly measure and verify the voltage at the lighting fixtures. This step is crucial for ensuring consistent and reliable illumination throughout your landscape. This information was last updated on January 19, 2022.

The voltage range for LED landscape lighting typically falls between 10 and 15 volts. To ensure that LED fixtures operate within this optimal voltage range, it is important to group them into distance zones as illustrated in the diagram below. This zoning approach helps distribute power effectively, maintaining voltage levels within the recommended range for the best performance and longevity of your landscape lighting system.
