Landscape Lighting Product Guides

Service-first guidance to stop flicker, fix dim zones, and keep lighting reliable — with fast diagnosis when you want it handled for you.

Voltage drop discipline Waterproof splices Transformer sizing & taps Smart control readiness

Not sure where the problem starts? Book service and we’ll diagnose the system on-site.

Company standard: We prefer contractor-grade fixtures designed for serviceability (Alliance Outdoor Lighting is a common fit), consistent LED retrofits, and disciplined, waterproof splice practices.
Smart Link (Green Guru): Smart control only helps if the transformer location stays reachable. Smart Link adds cellular internet and a local Wi‑Fi network at the install point for select deployments where property Wi‑Fi doesn’t reach (so control stays serviceable in real-world installs).

Common symptoms — fastest guide

Dim at the end

Voltage drop basics

Wire gauge and run length are the first checks when the far end looks weak.

Intermittent / flicker

Splice discipline

Most reliability failures are corrosion at connections—fix the splice, not the bulb.

Transformer questions

Sizing + taps

Correct tap selection helps you get predictable brightness without burning out lamps.

Power (transformers)

Wiring, splices & enclosures

Most "half the yard is dim" calls are voltage drop + corrosion at splices. Hub enclosures keep branch runs serviceable.

LED retrofits

Control (reachability)

Smart control only works when the transformer location stays reachable. If Wi‑Fi is weak (or doesn’t exist) at the transformer, Smart Link can add cellular internet and a local Wi‑Fi network at the install point so control stays serviceable.
