Usually they have not. We find where the circuit stops before anything is replaced.

Power leaves the house, passes through a transformer and a timer, and travels along a buried cable to each fixture in turn. A fault at any point takes out everything after it, so the place where the lights stop is rarely the place that is broken. Point 1 of 6 ### The outlet The transformer plugs into an outdoor outlet, and that outlet is protected by a ground-fault device that shuts off when it detects current leaking to ground. Outdoors, moisture is the usual reason. A whole system that goes dark at once, with no warning, often starts here and not in the yard. On the stairFrom the yard this looks exactly like a failed transformer or a timer that never switched on: every light is out, on every run. What we checkWhether the outlet has power, and what made it trip. Point 2 of 6 ### The transformer It steps house current down to low voltage for the yard. Every fixture adds to its load, so a transformer sized for the original system can be past its limit after years of additions. Many protect themselves by shutting off when they overheat and coming back when they cool, which looks like lights that quit some nights and not others. On the stairEverything it feeds goes out together, which is the same picture a tripped outlet makes. What we checkIts output, and the total load against what it is rated to carry. Point 3 of 6 ### The timer or photocell This decides when the lights run. A mechanical timer loses its place every time the power blinks, so the schedule drifts a little after each outage. A photocell stops seeing dusk when a plant grows over it or its lens clouds. On the stairThe system is healthy and simply has not been told to come on. What we checkThe settings, where the sensor sits, and what it actually does after dark. Point 4 of 6 ### The buried run The cable is only a few inches down, which is shallow enough for an edger, an aerator or a new planting hole to find it. Voltage also falls the farther it travels, so the last fixtures on a long run are fed less than the first ones. On the stairThe wall light is fed before the cut, so it stays on. The three steps after it go dark as a group. What we checkVoltage at the far end of the run, not just at the transformer. Point 5 of 6 ### The connections Each fixture joins the run at a splice. In ground that stays wet, a twist-on connector corrodes until it stops carrying current, and everything past that point goes dark together. It is the most common reason a section of a system fails in Southwest Florida. On the stairThe top step is before the failed splice and still lit. The two below it are not. What we checkEvery splice along the affected run, opened and remade where it has failed. Point 6 of 6 ### The fixture The part everyone suspects first. Lamps do fail, and thin aluminum housings pit from the inside in salt air, sometimes while the lamp inside still works. But a fixture is only the cause when it is the only thing that is out. On the stairOnly the bottom step is out, and everything else is lit. This is the one pattern where the fixture is the likely cause. What we checkThe housing, the socket and the seal, for corrosion and water. Found and fixed ### Back on Whichever point it was, the repair is the same idea. Find where the circuit stops, put that right, and every light after it comes back on its own. [Ask for a repair visit](https://www.nightscapeslandscapelighting.com/landscape-lighting-repair#lr-book) ### One section is dark Part of the yard is out and the rest still works. 1. Most likely A failed connection just before the first dark fixture. Everything past it loses power together, which is why a group goes out at once. 2. Next A cut cable. Edging, aeration and new planting all happen at the depth the wire is buried. 3. Also possible One output on the transformer has shut off, if that section runs on its own circuit. Where we startWe work back from the first dark fixture to the last lit one. The fault is almost always between the two. [Ask for a repair visit](https://www.nightscapeslandscapelighting.com/landscape-lighting-repair#lr-book) ### Everything is dark No fixture comes on anywhere. 1. Most likely The outdoor outlet has tripped. Moisture is the usual cause, and it normally resets with a button on the outlet itself or on another outlet on the same circuit. 2. Next The timer or photocell is no longer switching the system on. 3. Also possible The transformer has shut down on its own protection, or has failed. Where we startPower at the outlet first, then at the transformer, then what the timer is telling it to do. [Transformer and timer repair](https://www.nightscapeslandscapelighting.com/landscape-lighting-transformer-repair) ### The far lights are dim Fixtures near the house are fine and they fade toward the end of the run. 1. Most likely Voltage drop. The run is long, or carries more fixtures than its wire was sized for, often because fixtures were added later. 2. Next A corroding connection partway along that is still passing current, but less of it. 3. Also possible On a halogen system, lamps near the end of their life, which dim and yellow before they fail. Where we startA voltage reading at the first fixture and at the last. The difference says whether it is the wire, a joint or the lamps. [Redesign and expansion](https://www.nightscapeslandscapelighting.com/landscape-lighting-redesign) ### Lights flicker or come and go They work, then they do not, then they do again. 1. Most likely A loose or corroded connection that makes contact only some of the time, often changing with rain or irrigation. 2. Next Water inside a fixture, reaching the socket. 3. Also possible A transformer running over its load and cycling off and on as it heats and cools. Where we startWhether it follows the weather, the time of night or one particular run. Each points somewhere different. [Ask for a repair visit](https://www.nightscapeslandscapelighting.com/landscape-lighting-repair#lr-book) ### They come on at the wrong time On in daylight, off too early, or never off at all. 1. Most likely A mechanical timer that has drifted. Every power outage stops its clock, and it restarts from wherever it stopped. 2. Next A photocell that is shaded, dirty or has failed, so it no longer sees dusk when dusk happens. 3. Also possible A digital or app controller that lost its clock, its location or its connection. Where we startWhat the control thinks the time is, and what it can see from where it is mounted. [Transformer and timer repair](https://www.nightscapeslandscapelighting.com/landscape-lighting-transformer-repair) ### A single fixture is out Its neighbors on both sides are lit. 1. Most likely The lamp or LED module has reached the end of its life. 2. Next The socket has corroded, so a good lamp no longer makes contact. 3. Also possible That fixture’s own splice has failed while the run it hangs from is fine. Where we startThe lamp, then the socket, then the splice. This is the one case where the fixture really is the likely cause. [Relamping](https://www.nightscapeslandscapelighting.com/landscape-lighting-bulb-replacement) ### The light is in the wrong place Everything is on, but it is in your eyes or on the wrong thing. 1. Most likely The planting has grown. A fixture that lit a young palm now lights the middle of its trunk, or shines into a hedge that was not there. 2. Next A fixture has been knocked off its aim by mowing, trimming or a storm. 3. Also possible Mulch or soil has built up around a fixture and is blocking part of the beam. Where we startThe whole system, end to end, before any single part is blamed.

None of it is a fault in the lighting. It is the reason a repair that only replaces what is visibly broken tends to be followed by another one. - ### Salt air It reaches well inland on an onshore breeze. Thin aluminum pits from the inside, brass and copper last, and a socket that looks clean can be green underneath. - ### Ground that stays wet Summer rain arrives most afternoons, the water table is close to the surface, and irrigation runs year round. A splice that would last for years in dry soil sits in damp sand here. - ### Everyone who works in the yard Edgers, aerators, trimmers and new planting all happen at cable depth. Cut wires tend to turn up close to a bed edge. - ### Lightning and power blinks Florida is one of the most lightning-prone states in the country. Surges are hard on transformers and controls, and every brief outage resets a mechanical timer. - ### How fast everything grows A palm can outgrow the beam that was set for it in a few seasons. Nothing has failed, but the light is no longer where it was aimed. - ### Repair what is there It fits when The layout still suits the property, and the trouble is confined to a run, a connection, the transformer or a handful of fixtures. What changes The failed parts, and the connections around them. What stays Your fixtures, your layout and your wiring. [Ask for a repair visit](https://www.nightscapeslandscapelighting.com/landscape-lighting-repair#lr-book) - ### Convert halogen to LED It fits when An older halogen system that still works, but goes through lamps, runs warm, or fades toward the ends of its runs. What changes Lamps or fixtures move to LED, which draws a fraction of the power, so the same wire and transformer carry the load with room to spare. What stays The layout and, where it is sound, the wiring. [Halogen to LED retrofit](https://www.nightscapeslandscapelighting.com/halogen-to-led-retrofit) - ### Redesign and expand It fits when The planting has outgrown the lighting, the property has changed, or the original design never did what you wanted it to. What changes Fixture positions, zones and often the transformer. What stays Whatever is sound and still in the right place. [Redesign and expansion](https://www.nightscapeslandscapelighting.com/landscape-lighting-redesign) On a repair visit ## What we check, in order The first thing we do is find where the circuit actually stops. That means working back along the run to the connections, the transformer and the wire itself before anything gets replaced. It is slower than swapping the fixtures that are dark, and it is the only way a repair lasts. The point of the visit is to find the cause, not the symptom.

Choose a question, or call and we will answer it on the phone. ### Why did half my landscape lights go out at the same time? Because they share a wire. The fixtures on a run are fed one after another, so when a connection fails or the cable is cut, everything past that point loses power together. It is rarely several fixtures failing at once. It is one fault, upstream of the first dark light. ### Can I just replace the fixture that is not working? If it is a single fixture with lit neighbors on both sides, the lamp or the fixture is a reasonable place to start. If a group is out, a new fixture at the end of a dead run will not light either, because the power is not reaching it. ### Why are the lights at the end of the run dimmer than the ones near the house? Voltage falls as it travels along the cable. A long run, a thin wire or too many fixtures on one circuit all make the drop larger, and the last fixtures show it first. It often appears after fixtures were added to a system that was sized for fewer. ### Is an old halogen system worth repairing? Often, yes, when the wiring and the layout are sound. The question is usually whether to keep feeding it halogen lamps or to convert it to LED while the work is being done, since LED draws far less power and takes the strain off the same wire and transformer. ### My lights come on in the afternoon. Is something broken? Usually it is the control and not the lights. A mechanical timer stops whenever the power does and restarts from where it stopped, so after a few outages it can be hours out. A photocell that is shaded by new growth will also switch on early. ### What should I check after a storm? Whether the outlet the transformer plugs into has tripped, whether any fixtures have been knocked over or buried, and whether sections that worked before are dark now. Standing water and fallen limbs both find the weak points in a system.
