No — leaving your landscape lighting running on its normal schedule while you’re away is actually the better move, not the more cautious one. The common instinct is to turn things off while traveling, either to save money or to avoid drawing attention to an empty house.

Neither reason holds up once you look at what’s actually driving the cost and the security logic.

The Cost Isn’t the Reason to Turn It Off

A low-voltage LED landscape lighting system typically adds somewhere between $2 and $7 a month to an electric bill, whether or not you’re home to see it. That’s a small enough number that leaving the system running its normal schedule for a week or two of travel isn’t a meaningful expense — for the full cost breakdown by system size, see how much landscape lighting actually costs to run. If cost is the reason you’ve been turning your system off while traveling, it’s solving a problem that barely exists.

Why Turning It Off Actually Stands Out More

The security logic gets borrowed from indoor lighting, but it doesn’t transfer the way people assume. An indoor lamp that burns at the exact same hour every single night, whether or not anyone’s home, reads as unnatural precisely because a lived-in home’s indoor lighting normally varies — someone’s in the kitchen, then the living room, then a bedroom light goes off. A single static lamp on a timer is trying to fake that variation and often fails to.

Landscape lighting doesn’t work that way, and it was never trying to. A path light or uplight on a photocell or timer turns on at dusk and off at a set hour every night, occupied or not — that’s its normal, expected pattern regardless of who’s home. It’s not standing in for a person moving through the house; it’s an architectural feature that runs on a schedule by design. Turning it off specifically while you’re traveling is the change that stands out, not the thing that blends in. A house that’s normally lit every night and suddenly goes dark for a week is more noticeable than one that keeps its usual pattern.

What Actually Deters an Intruder

Static lighting alone, landscape or indoor, isn’t a strong deterrent by itself — security research consistently points to motion-activated lighting as more effective, since it reacts to someone’s actual presence rather than just existing as background glow. A fixture that suddenly brightens or activates when someone approaches an entry does something a steady glow can’t: it signals that the property is actively monitored, not just lit.

This is a good reason to layer motion-activated fixtures at entries and dark corners alongside your regular landscape lighting rather than relying on either one alone. The photocell-driven landscape lighting keeps the property looking normally occupied every night, and motion-activated lighting adds an active response layer specifically at the points someone would actually approach the house. Paired with other visible measures — a camera, a doorbell camera, alarm signage — lighting becomes one part of a combined approach rather than the single line of defense, which is generally what security guidance recommends over any one measure on its own.

Landscape Lighting Vacation Mode: What It Actually Does

If you’ve come across “vacation mode” for landscape lighting, it’s a real feature on some smart, app-controlled transformers, and it works differently than most people expect. Rather than turning the system off, it slightly randomizes on and off times each night within a set window, so the pattern looks less mechanically identical from one night to the next.

It’s the same logic used in smart indoor lighting during a trip, applied to the transformer instead of a lamp. It’s a nice-to-have layer on top of a normal timer or photocell schedule — not a requirement, since a standard photocell already covers the core job of running the system every night without you having to think about it. (For more on how timers and photocells work together day to day, see our guide on whether you need a timer for landscape lighting.)

Landscape Lighting Is One Layer, Not the Whole Plan

It’s worth being honest about what landscape lighting can and can’t do on its own. It’s not a security system, and it’s not going to single-handedly prevent a break-in. What it does well is remove one of the signals — a dark, unlit property at night — that makes a home look obviously unoccupied. That’s a meaningful piece of a broader approach, but it works best alongside the other basics: holding mail and packages so they don’t pile up visibly, asking a neighbor to keep an eye on the property, parking a car in the driveway occasionally if someone’s willing, and being cautious about posting specific travel dates publicly before or during a trip.

None of that has anything to do with landscape lighting directly, but it’s the context that makes “leave the lighting on its normal schedule” the right piece of a much bigger picture rather than a single fix.

What to Actually Do Before You Leave

Rather than shutting the system down, a few things add real value before a trip:

• Leave it on its normal schedule. A photocell or timer that runs every night is consistent with an occupied home, whether or not it actually is one.
• Check that motion-activated fixtures at entries are working. These matter more while you’re away than the ambient landscape lighting does, since they’re the layer that responds to an actual approach.
• Have someone check the property periodically, especially during storm season, so any issue gets caught and addressed rather than sitting unnoticed for the length of the trip.
• Get the system looked at before you leave if it’s been a while since a maintenance check — a loose connector or worn seal is better caught while you’re still around to have it fixed.

The short version: a trip out of town isn’t a reason to change your landscape lighting’s routine. Consistency is doing more work for you than a shutdown ever would.
