Halogen to LED
Many halogen fixtures accept LED lamps, cutting energy use dramatically. We match LED lamps to your transformer and check that voltage is in range.

Landscape Lighting Repair in Texas
We find and fix what is wrong with your outdoor lighting, from a single dark fixture to a dead transformer, including systems another company installed.
Outdoor lighting lives a hard life in Texas. It gets baked, flooded, frozen, mowed around and dug under. Sooner or later something stops working. Landscape lighting repair in Texas is about finding the real cause quickly and fixing it in a way that holds up, instead of swapping lamps every few months and hoping.
Texas Landscape Lights repairs and upgrades low-voltage systems across the state, including systems installed by other companies, DIY kits and older halogen setups. We diagnose first, explain what we find in plain language and give you a written estimate before doing the work.
- One or more fixtures dark while others work
- An entire section of the yard dark at once
- Lights flickering, cycling on and off or dimmer than they used to be
- Lights at the end of a run noticeably weaker than those near the transformer
- Timer or photocell not turning lights on, or lights stuck on during the day
- Fixtures tilted, crushed, filled with water or cloudy behind the lens
- A transformer that hums loudly, smells hot or trips its breaker
If any of those sound familiar, the system probably needs a technician rather than a new bulb.
The most common causes we find
| Symptom | Likely cause | Typical fix |
|---|---|---|
| Single fixture dark | Failed lamp, corroded socket or water intrusion | Replace lamp or LED module, clean or replace socket, reseal or replace fixture |
| Whole run dark | Cut wire from edging, aeration, trenching or roots | Locate break, splice with waterproof connectors, rebury deeper |
| Flickering or intermittent | Loose or corroded connection, low voltage, incompatible LED lamp | Remake connections, rebalance load, match lamps to transformer |
| Dim at far end | Voltage drop from long runs or undersized wire | Hub wiring, heavier gauge, adjusted taps |
| Nothing works | Tripped GFCI, failed transformer, bad timer or photocell | Reset and test, replace controller or transformer |
Wire damage from lawn care and roots
The most common repair we make is a cut cable. Edgers along beds, aeration tines, new sprinkler lines, fence posts and tree planting all slice through shallow wire. Large roots, especially under live oaks, can also squeeze and abrade cable over time. We trace the break with a wire locator, splice it with gel-filled connectors and rebury the cable deeper or reroute it away from the hazard.
Corroded connections
Many kit and builder-grade systems use push-pierce connectors that clamp onto the cable. Moisture creeps into the pierced insulation, the copper turns green and resistance rises until the light flickers or dies. Clay soils that stay wet and Gulf Coast humidity speed this up dramatically. We replace those connectors with sealed, gel-filled splices.
Transformer and controller failure
Transformers can fail from heat, overload, lightning or simple age. Timers and photocells fail even more often. After big outages or storms, controllers may lose their programming. We test output voltage on each tap, check the load against the transformer rating and repair or replace as needed. If a dedicated outlet or circuit is required, a licensed electrician handles that line-voltage work.
Fixtures knocked out of aim
Not every problem is a failure. Mowers bump stakes, dogs dig, clay soil heaves after a wet spring and trees grow into or away from their lights. A fixture that has rotated a few degrees can throw glare into a window or light the sky instead of a canopy. Re-leveling and re-aiming is part of every landscape lighting repair visit we make in Texas, and it often makes an older system look new again.
Voltage drop
Low-voltage systems lose voltage over distance. On older halogen systems this showed up as yellow, dim lights at the end of a run. LEDs tolerate a wider range but can still flicker or shut off when voltage falls too low. The transformer sizing calculator explains the relationship between wattage, wire gauge and run length.
How a repair visit works
Diagnosis matters more than speed. We work through the system from the source outward so we fix causes, not symptoms.
Check power and controls
We confirm the outlet and GFCI, test the timer or smart controller and measure transformer output on each tap.
Test each run
Voltage readings at the first and last fixture on each run show where losses or breaks occur.
Inspect fixtures
We open and inspect suspect fixtures for water, corrosion, damaged sockets and failed lamps or LED boards.
Explain and estimate
You get a clear summary of what we found and a written estimate, with priorities if the list is long.
Repair and adjust after dark
Once repairs are complete, we check every fixture at night, re-aim anything that has drifted and reset schedules.
Landscape lighting repair for systems installed by others
Many of our repair calls come from homeowners whose original installer is no longer around, or who bought a house with lighting already in place. We work on most brands of low-voltage fixtures and transformers. Sometimes the best answer is a targeted repair. Other times a system has so many corroded fixtures and failing splices that replacing it in stages makes more sense. We will tell you which one you are looking at, and why.
We also see plenty of DIY and big-box kits. They are often wired in a single long daisy chain with thin cable and plastic fixtures. Those can usually be improved by rewiring to a hub layout, upgrading the transformer and gradually replacing the fixtures that fail first.
Fixture upgrades
Faded plastic and corroded aluminum fixtures can be swapped for brass or copper that will handle Texas sun and humidity for years.
Timer upgrades
Replacing an old mechanical timer with an astronomical or smart controller keeps lights in sync with the sunset.

After storms, floods and freezes
Texas weather causes a lot of lighting damage. Hail can crack lenses in North Texas. Flash floods can fill fixtures and transformer boxes with silt. Hard freezes like February 2021 can split fixture housings that held water and leave controllers scrambled after long outages. Tropical storms on the Gulf Coast bring wind, debris and fallen limbs. Even when everything still lights up, a storm can shift fixtures, bury them in mulch or leave lenses coated in mud, so a quick night walk after severe weather is always worth the time.
Safety first: If a transformer or outlet was submerged in floodwater, keep it unplugged and have it inspected before use. The lighting is 12V, but the outlet and the transformer's input side are line voltage.
Our guide to protecting landscape lighting from Texas storms covers prevention. When damage does happen, we can inspect the system, replace what is broken and get it back on schedule.
We provide landscape lighting repair for homes across Fort Worth, Round Rock, Houston, Dallas, Austin and San Antonio. Book a visit and we will track down what is wrong and give you a straight answer on the fix.

FAQ
Questions & answers
Do you repair systems installed by other companies?
Yes. We work on most low-voltage landscape lighting systems regardless of who installed them. We start by diagnosing the transformer, wiring and fixtures, then explain what is worth repairing and what should be replaced.
Why did half of my lights stop working at once?
When a group of fixtures goes dark together, the cause is usually a cut or damaged wire, a failed connection on that run or a tripped circuit on the transformer. Individual dead fixtures are more often a lamp, socket or fixture problem.
Why are the lights at the end of my run dimmer?
That is usually voltage drop. Long runs, undersized wire or too many fixtures on one cable reduce voltage at the far end. Rebalancing runs, using heavier wire or changing transformer taps typically corrects it.
Is it worth converting halogen landscape lights to LED?
In most cases, yes. LED lamps or fixtures use a fraction of the power, run cooler and last far longer. Some halogen fixtures accept LED lamps directly, while worn or corroded ones are better replaced.
How much does landscape lighting repair cost?
It depends on what we find. A loose connection or single lamp is a small job, while rewiring a run or replacing a transformer costs more. We diagnose first and give you a clear written estimate before any repair work.
