Landscape Lighting Maintenance Tips to Keep Your System Shining Bright

Protect your investment and keep your property glowing year-round

You’ve invested in a high-quality outdoor lighting system—now make sure it performs beautifully night after night. Just like any home feature, landscape lighting needs occasional maintenance to stay in top shape.

At TPG Lighting, we build systems to last, but regular upkeep ensures your fixtures stay bright, your wiring stays safe, and your home continues to look its best after dark. Here are our top tips for maintaining your landscape lighting system:

1. Clean Lenses and Fixtures Regularly

Dirt, dust, hard water, and debris can accumulate on the lens of your fixtures, reducing brightness and clarity. A simple wipe with a soft cloth and mild soap every few months will help keep the light output strong and even.

• Avoid harsh chemicals

   

• Use a soft microfiber cloth

   

• Check for hard water stains near irrigation zones

   

2. Trim Back Landscaping

As your trees, shrubs, and plants grow, they may begin to block light beams or cast unwanted shadows. Trimming back overgrowth ensures your lights are illuminating what they were designed to highlight.

• Keep fixtures clear of foliage

   

• Maintain open sightlines to focal points

   

• Prevent leaves from resting on hot lenses

   

3. Check for Moisture Intrusion

Even high-quality, weather-resistant fixtures can occasionally let moisture in—especially after storms or irrigation run-off. If you notice fogging inside a lens, it’s time to have the seal inspected or the fixture replaced.

• Look for signs of condensation

   

• Inspect wiring for corrosion

   

• Ensure fixtures remain securely mounted

   

4. Adjust Angles and Positions as Needed

Ground movement, foot traffic, and weather can shift fixtures slightly over time. It’s a good idea to walk your property at night and check if beam angles or spotlight positions need fine-tuning.

• Reset path lights for optimal coverage

   

• Realign uplights to trees or columns

   

• Re-bury exposed wires to prevent tripping

   

5. Replace Burned-Out or Dimming LEDs

While LED bulbs last significantly longer than traditional options, they don’t last forever. Dim or flickering lights may indicate a dying bulb or transformer issue.

• Use matching color temperatures (2700K–3000K recommended)

   

• Contact us for replacements if your fixtures are under warranty

• Don’t mix bulb types—consistency is key
