Fixtures out, lights dimming toward the end of a run, a transformer that keeps tripping — low-voltage lighting fails in specific, findable ways. We test the system after dark, where the problem actually shows itself.
A single dark fixture usually means a failed lamp or connection. Several dark at once points to the transformer, a zone, or a break in the cable.
The classic sign of a voltage drop. If the last fixtures are noticeably weaker than the first, the run is overloaded, or the wire gauge is undersized.
Flicker almost always traces to a loose or corroded connection, a failing lamp, or moisture that has found its way into a fitting.
Coming on at noon, staying off at dusk, or drifting week to week points to the timer, photocell, or controller rather than the fixtures.
Condensation inside a lens, green corrosion at the socket, or standing water in the housing means seals have failed and the fixture is on its way out.
Cut cable, knocked-over fixtures, and lights buried by grown-in beds are among the most common causes we're called out to repair.
Low-voltage lighting is a system, not a set of separate lamps. Most problems trace back to power, connections, or water — and most are fixable without starting over.
Units that hum, trip, run hot, or have simply stopped. We confirm the transformer is actually the fault before replacing it.
Dim fixtures at the end of a line can be corrected by rebalancing the run, adjusting tap connections, or upgrading the wire.
Buried splices are the most common failure point in any system. We locate the break and repair it with weatherproof connections.
Lights on the wrong schedule get traced to the timer, photocell, or controller — then repaired, reprogrammed, or upgraded.
Fixtures knocked out of alignment, sunk into beds, or swallowed by grown-in landscaping are reset so the design reads the way it was intended.
You can inspect a fixture in daylight, but you can't judge a lighting system until it's running. That's why our diagnosis happens when the system is actually on.
We map the runs, check the transformer and controls, and look over every fixture, connection, and length of exposed cable.
We measure voltage at the fixtures, not just the transformer — the only way to catch voltage drop, bad splices, and failing runs.
