Why did all my landscape lights stop working at once?

The fault may affect the shared supply or controls. When every light goes out together, the outlet, transformer, controls and shared connections need checking before treating each fixture as a separate failure. Tell Carlos whether all the lights are off, whether a breaker has tripped, and whether the problem followed a power outage or yard work.

When should I arrange landscape lighting maintenance?

When the light output, aiming or schedule changes. Call about dark or dim fixtures, lights shining into windows, plant growth blocking a beam, or a schedule that no longer fits the evening. Cleaning, re-aiming, control adjustments and repairs are different tasks, so describe what has changed rather than assuming every fixture needs replacing.

Does an LED upgrade mean replacing the whole lighting system?

Not necessarily; condition and compatibility decide. Some existing equipment may be suitable to keep, while worn fixtures, damaged connections or insufficient capacity can change the scope. Ask for the repair and upgrade options to be considered together. A new lighting layout can be discussed separately if the current one no longer suits the yard.

Landscape Lighting Repair & Maintenance in the Fairfield Area

If landscape lights are dim, out or on at the wrong time, start with the existing system. We assess power, controls, cable and connections before recommending repairs or replacements. Maintenance can include cleaning and re-aiming fixtures; an LED upgrade depends on the condition and compatibility of the equipment in place.

Why do landscape lights go dark?

Which lights are out tells you where to look. All of them points to the power; one run points to a connection; dim lights at the far end point to the cable. Pick what you’re seeing, and the drawing marks where we check first.

Sample system drawn for this page, not a customer’s yard: an outlet and transformer, a home run to a hub, then three runs (a bed of path lights, two uplights on one tree, a long chain of path lights).

Every light on. Pick what you’re seeing above: the lights it puts out go dark, and the places we check first turn blue.

Should an older halogen system go LED?

Yes, when the fixture bodies are sound.

An LED lamp uses a fraction of a halogen lamp’s power and lasts several times as long. On the example twelve-light system here, the load falls from 240 to 60 watts of a 300-watt transformer, leaving room for new lights. Choose the color on purpose: early LEDs ran blue, and warm white keeps halogen’s look. Sound fixtures keep their housings and get new lamps; cracked or flooded ones are replaced.

Keep the light on its target: use only the brightness needed, shield the beam from neighboring windows, and choose a warm color. Timers or other controls keep decorative lights from running when they are not needed. We can assess the existing fixtures before deciding what should stay.

How much of the transformer the lights use

Halogen

LED

Example system, not a customer’s: the same twelve lights on one transformer, on halogen and on LED.

What happens on a lighting service visit?

Half of it happens in daylight, half after dark.

In daylight

We open the transformer, measure its load against its rating, and test the breaker, photocell, timer and backup battery. Every connection is checked; any that has let water in is replaced and sealed. Lenses get cleaned, buried fixtures dug out, leaning ones re-staked, and a spray head fouling a fixture is turned: the same crew works on irrigation.
