How to Connect Low Voltage Landscape Lights?
Connecting low voltage landscape lighting is an easy DIY project that can dramatically transform the look of your yard and gardens at night. Here are the steps to follow:
Things You'll Need
- Low voltage landscape light fixtures
- Low voltage landscape lighting wire
- Wire connectors
- Screwdriver
- Voltmeter
Instructions
- Plan out where you want to place the landscape lights and how you will run the wiring between them.
- Install the light fixtures where desired following the manufacturer's instructions.
- Run the low voltage landscape wire between each light, leaving some extra wire at each end for connections.
- At the transformer, connect the landscape lights wire leads to the low voltage terminals using wire connectors.
- Connect the transformer to an outlet and test that all lights are working using a voltmeter to check the voltage.
- Make any necessary wiring adjustments to get all lights functioning.
- Bury and secure any exposed landscape lighting wires.
Using quality waterproof connectors and outdoor-rated landscape lighting wire is key for a long-lasting system. Also be sure to follow local codes for outdoor lighting installation. With the right materials and safe setup, you can enjoy the convenience and beauty of low voltage landscape lights.
How to Waterproof Outdoor Landscape Light Connectors?
Outdoor landscape lighting is exposed to the elements, so it's important to properly waterproof connections to prevent shorts or damage. Here are some tips for waterproofing connectors used in low voltage landscape lighting:
Choose Weather Resistant Connectors
Opt for outdoor-rated, gel-filled wire connectors or twist-on wire connectors. These are designed to seal out moisture. Avoid standard plastic wire nut connectors.
Use Heat Shrink Tubing
- Cut heat shrink tubing to fit snugly over each connector.
- Slide tubing over wires before connecting.
- Apply heat from a hair dryer or heat gun to shrink the tubing.
- The tubing will create a tight seal around the connections.
Seal Ends with Waterproof Tape
Wrap weatherproof electrical tape around ends of connectors to provide an extra barrier against water penetration.

Use Dielectric Grease
Coat all connections with dielectric grease before covering them. The grease will displace moisture and prevent corrosion.
Test Waterproofing
Test waterproofed connections by spraying with a hose. Check for moisture inside with a voltmeter. Make any needed adjustments to ensure connectors are fully sealed.
Properly waterproofed connectors will withstand outdoor environments for many years. Always check connectors periodically for corrosion buildup or damage. Re-waterproof as needed to maintain a functioning lighting system.

Test Voltage
- Use a voltmeter to check voltage at each light fixture.
- Low or no voltage indicates a wiring issue.
- Check for cut, damaged, or undersized wires.
Replace Defective LEDs
- Swap in a new identical LED light module if fixture has no power.
- Only replace with compatible, outdoor-rated LEDs.
Check Transformer
- Inspect transformer connections and output voltage.
- Reset GFCI outlet or breaker connected to transformer.
- Replace transformer if output is too low.
Also check for issues like photoeye sensors, timers, or switches not working properly. With some basic troubleshooting, you can get LED garden path lights working again and enjoying your landscape at night.
How to Choose the Right Gauge Wire for Outdoor Lighting?
Selecting the proper wire gauge for your outdoor lighting installation is important for safety and performance. Here are some tips:
Consider Length of Wire Runs
The longer the wire run from the transformer to the lights, the thicker the gauge needs to be to avoid voltage drop. Some general guidelines:
- Up to 75 ft run: 16 or 18 AWG
- 75 to 150 ft run: 14 AWG
- Over 150 ft run: 12 AWG
Factor in Power Load
The more wattage your lighting system draws, the thicker the wire should be. For example:
- 300 watt max load: 12 AWG
- 600 watt max load: 10 AWG
- 1000 watt max load: 8 AWG
Consider a Safety Factor
For important areas like driveways, steps and paths, choose a wire 1-2 gauges thicker than minimum recommended to allow for expansion and heavy use over time.
Buy Quality Outdoor Rated Wire
Spend a little more for durable, outdoor-rated wire made of copper or corrosion resistant alloys. Look for wires rated for direct burial.
Follow Codes and Manufacturer Recommendations
Consult local electrical codes for outdoor lighting wire requirements. Also check transformer or fixture manuals for specific gauge guidelines.
Choosing the right wire size will prevent safety hazards, maximize lamp life and reduce the need for repairs. Investing in quality wiring makes for a long-lasting outdoor lighting system.
