Low-Voltage vs Solar Landscape Lighting: Which Belongs on a Designed Property?

TL;DR: Low-voltage wired systems give you designable brightness, reliability, and fixture quality that solar path lights can't match — solar's role is limited to spots wire genuinely can't reach. If lighting is part of the design, wire it.

What's the difference?

• Low-voltage (12V) systems: a transformer steps down house current; buried cable feeds brass or copper fixtures. Output, beam control, and dimming are all designable — this is what professional outdoor lighting design means.
• Solar fixtures: self-contained units with a small panel and battery. No wiring — and no control over output, which depends on yesterday's sun and the battery's age.

When does each make sense?

• Designed landscapes, entries, trees, architecture, steps, and any safety lighting → low-voltage, always: consistent output every night of the year.
• A remote gate or dock far from any transformer run → a quality solar unit beats trenching hundreds of feet.
• Renters and temporary situations → solar as a stopgap, understood as such.

What are the failure modes?

• Solar in coastal marine layer. June-gloom weeks starve the panels; the lights dim exactly when evenings are longest.
• Plastic fixture attrition. Big-box solar and cheap 12V fixtures both fail fast in salt air — brass and copper survive it and age well.
• Wired systems without design. A transformer and twenty identical path lights isn't lighting design — layering, beam angles, and restraint are (see the San Diego landscape lighting guide).
• Voltage drop from bad wiring runs — distant fixtures go dim when runs weren't calculated.

What does the design-build view add?

Lighting is the last phase of the build sequence, but its conduit goes in early — another reason phased projects need one master plan. Bradley Landscape has designed coastal properties since 1989; the lighting that still works decades later is wired, serviceable, and specified for marine air.
