Arizona Landscape Lighting Maintenance: A Seasonal Checklist

The short answer

Inspect your system at least twice a year and after major weather. Clean lenses, straighten shifted fixtures, trim plant material away from beams, check exposed wire, confirm schedules, and look for moisture or corrosion. Turn off power before touching wiring or opening equipment.

The homeowner checklist

Clean lenses and fixture faces

Dust, mineral deposits, irrigation overspray, and landscape debris reduce output and soften beam edges. Use a gentle method recommended for the fixture material; abrasive cleaners can damage finishes and glass.

Check aim and alignment

Foot traffic, yard work, animals, soil movement, and irrigation repairs can shift stake-mounted lights. Evaluate the system after dark and aim fixtures away from windows, seating positions, and direct sightlines.

Manage plant growth

A fixture aimed at a young tree may disappear inside foliage months later. Trim around the beam path and reassess the aim as trunks, canopies, palms, and shrubs mature.

Look for wire exposure

Erosion and landscaping can bring buried cable to the surface. Do not leave damaged or exposed connections unattended. Mark the location and have a qualified professional inspect the run.

Review the transformer and controls

Confirm that schedules still match sunset and your routine. Check for unusual sounds, heat, tripped protection, insects, damaged covers, or moisture. Keep the area around the transformer accessible.

After monsoon weather

Walk the property in daylight first. Look for displaced fixtures, fallen branches, washed-out soil, standing water, loose bistro hardware, and exposed cable. Test the system only when conditions are safe and dry enough to do so.

When to call for service

Repeated outages, flickering, multiple dim fixtures, visible wire damage, burning odors, a transformer that trips, or water inside a fixture deserve professional attention. A focused repair can often restore the design without replacing the entire system.
