Most conversations about landscape lighting start and end with the installation price. That makes sense. It is the biggest number on the page. But it is not the only number, and it is not the one homeowners ask us about most after the system is in the ground.

The question we hear over and over is some version of this: "Okay, but what is this going to do to my electric bill? And what does it cost to keep it working?"

Those are fair questions, and you deserve straight answers before you sign anything. So here is what it actually costs to own a landscape lighting system in Fort Worth, year after year.

The short answer

For a modern low-voltage LED system on a typical Fort Worth home, the electricity usually works out to a few dollars a month. Routine upkeep is modest: an annual checkup plus the occasional repair when a string trimmer finds a wire or a tree grows over a fixture.

The homeowners who end up spending real money on their lighting after installation are almost always the ones with older halogen systems or systems that were built with cheap parts and poor connections. We will get to why.

How much electricity does landscape lighting use?

Less than most people expect. Professional landscape lighting today runs on low-voltage LED fixtures. A transformer steps your home's 120-volt power down to roughly 12 volts, and the fixtures run from there.

LED fixtures are very efficient. The U.S. Department of Energy says residential LEDs use at least 75 percent less energy than incandescent bulbs. In practical terms, a typical LED path light draws only a few watts, and most tree and architectural uplights fall somewhere in the range of about 4 to 20 watts depending on how much light the feature needs.

Add it all up and a 15 to 25 fixture residential system often totals somewhere between about 75 and 200 watts. That is roughly the draw of one or two old-fashioned incandescent light bulbs, spread across your whole yard.

What it costs to run in Fort Worth: the math

You can figure your own cost with one simple formula:

Total watts ÷ 1,000 × hours per night × 30 days × your rate per kWh = monthly cost

For the rate, Texas homes paid an average of about 15.9 cents per kilowatt-hour in mid-2026, according to U.S. Energy Information Administration data. Fort Worth is in a deregulated electricity market, so your actual rate depends on the plan you picked. Check your bill and plug in your own number.

Here is what that looks like at about 16 cents per kWh with lights running 6 hours a night:

Small system, about 75 watts: roughly $2 a month
Medium system, about 150 watts: roughly $4 a month
Large system, about 300 watts: roughly $9 a month

A couple of notes so you are not surprised:

Runtime matters as much as wattage. Most of our clients run their lights from dusk until around bedtime. If you choose dusk to dawn, your hours roughly double in winter, and so does the cost.
The transformer uses a little power of its own. Real-world numbers will run a bit higher than the simple fixture math. Even so, for a properly designed LED system, it stays small.
Sunset moves a lot here. In Fort Worth, sunset ranges from a little after 5 p.m. in December to around 8:40 p.m. in late June. A transformer with an astronomical timer or photocell adjusts automatically, so you only pay for the hours the lights are actually useful.

For most families, landscape lighting will be one of the smallest line items on the electric bill. It is not going to move the needle the way your air conditioner does in August.

Why older halogen systems cost more to own

If your home came with an older halogen system, the picture changes.

Halogen landscape lamps commonly draw 20 to 50 watts each. A 20-fixture halogen system at 35 watts per fixture is about 700 watts. Run that 6 hours a night at 16 cents per kWh and you are looking at around $20 a month, several times what a comparable LED system costs.

Electricity is only part of it. Halogen lamps burn out regularly, typically lasting a few thousand hours, so someone has to keep replacing them. They also run hot, which is hard on fixtures, lenses, and nearby plants.

This is why we often recommend that homeowners with older systems look at an LED upgrade. If the fixtures, wiring, and transformer are still in good shape, converting to LED can be more cost-effective than starting over, and it usually cuts both the monthly power cost and the maintenance calls. We cover this in more detail in our post on LED vs. halogen landscape lighting.

What routine maintenance actually involves

A well-built LED system is low maintenance. It is not no maintenance. North Texas is hard on outdoor equipment: long hot summers, sudden storms, irrigation overspray, clay soil that shifts, and trees and shrubs that grow fast.

A typical annual service visit should include:

Cleaning lenses. Dirt, water spots, and leaf debris dull the light output over time.
Re-aiming fixtures. Lawn crews, pets, and kids bump fixtures out of position. A light that was perfectly placed on day one may be pointing at a fence a year later.
Trimming around fixtures. Plants grow over path lights and block uplights. This is the most common reason a system "doesn't look as good as it used to."
Checking connections and wire. Making sure splices are sound and wire has not worked its way to the surface.
Checking the transformer and timer. Confirming the system is running the schedule you want and the transformer is not overloaded.
Adjusting the design as the landscape matures. A young tree that was not worth lighting five years ago might be the best feature in the yard now.

Many homeowners can handle simple things themselves, like wiping off a lens or nudging a path light back upright. The connection, voltage, and transformer checks are where a professional earns their keep.

What maintenance and repairs typically cost

Every company prices this differently, and every property is different, so treat these as general market ranges rather than a quote.

Annual maintenance plans: National cost guides commonly put basic one-visit plans in the low hundreds of dollars per year, with multi-visit plans and larger systems running higher.
Service calls: Many lighting companies charge a minimum trip or diagnostic fee, often somewhere around $75 to $150 nationally, before any repair work.
Common repairs: Angi's 2026 cost data puts most landscape lighting repairs in the range of about $20 to $600, with an average around $250. A cut wire or a single damaged fixture is on the lower end. Transformer replacement or tracing a hidden wiring fault is on the higher end.

The pattern we see is simple. Systems built with quality fixtures, properly sized wire, sealed connections, and a transformer with room to spare rarely need more than a checkup. Systems built cheap tend to generate repair calls, and those calls add up fast.

How to keep long-term costs low

You have more control over ownership costs than you might think. Here is what makes the biggest difference:

1. Start with LED and a quality transformer. Efficient fixtures keep the power bill low, and a properly sized transformer is the foundation of a system that lasts.

2. Use an astronomical timer, photocell, or smart control. Lights come on when you need them and turn off when you don't, without you ever touching a dial.

3. Choose fixtures built for Texas weather. Corrosion and heat are the enemies. Ask what the fixtures are made of and what the warranty covers.

4. Make sure wire is buried properly. Shallow wire is the number one target for edgers and aerators.

5. Tell your lawn crew where the lights are. A quick walk-through with your landscaper can save you a service call.

6. Schedule a yearly checkup. Small problems like a loose connection or a fixture getting buried in a shrub are cheap to fix early and more expensive later.

7. Ask about the warranty before you buy. Know what is covered, for how long, and who comes out when something goes dark.

The bottom line

A professionally designed LED landscape lighting system in Fort Worth typically costs a few dollars a month in electricity and a modest amount each year to keep looking its best. The installation is the big decision. After that, ownership should be easy and inexpensive, as long as the system was built right in the first place.

Fixture wattages (LED path lights "a few watts," uplights "about 4 to 20 watts," halogen "20 to 50 watts") are general industry figures from public guides, not measured on TNS systems. Ryan should confirm they match the fixtures TNS installs.
"Most of our clients run their lights from dusk until around bedtime." Ryan confirmed this is accurate TNS experience (Oct 19, 2026). Keep as written.
Fort Worth sunset range: checked with a standard solar calculation (about 5:23 p.m. CST in early December, about 8:41 p.m. CDT in late June). Low risk.
Electricity math leaves out transformer losses and standby draw on purpose. The text says real-world cost runs "a bit higher."
