Outdoor Lighting Installation in Clarendon, Virginia
Founder Sufian built Lawn Theory on eight years of military discipline earned during Operation Iraqi Freedom, and that same standard governs every transformer sizing, wire run, and timer setting we install. A low-voltage system is only as good as its weakest connection \— undersized transformers, exposed splices, and guesswork timers are how "landscape lighting" turns into a service call six months later.
The Short Answer
A professionally installed low-voltage landscape lighting system for a typical Clarendon home runs $2,500–$7,500, with most projects landing near $3,500–$5,000 for 12–20 fixtures covering a front walkway, entry, and accent trees. Fixture-only pricing runs roughly $100–$200 installed per light depending on type (path, uplight, or wash) and wire-run distance. Because these systems run on 12-volt transformers, most residential installs in Fairfax, Loudoun, Prince William, Arlington, and Alexandria are exempt from a building permit — we still pull one whenever a project ties into house power or a irrigation-timer panel, per current Virginia electrical code. Most installs are designed, wired, and lit up in a single day.

What Neighbors Say
Trusted on Homes Like Yours
“We hired Lawn Theory for pressure washing and landscaping. It is like we have a brand new home. Five stars!”
“They explained why they'd soft-wash our deck instead of blasting it with a wand, and I appreciated that. Came out clean without a single splintered board.”
“Written quote same day, on time for the appointment, and our HOA letter about the driveway staining is officially resolved. Would use again for our patio next.”
Clarendon, Answered
Outdoor Lighting Installation in Clarendon — Common Questions
What does low-voltage landscape lighting actually include?
A complete system runs on a 12-volt transformer stepped down from standard household power, distributing safe, low-draw current through buried or concealed wiring to path lights, wall-wash or uplight fixtures on trees and facades, and recessed step lights. On a Clarendon property, that typically means a walkway run, a few tree or wall accents, and step lighting on any exterior stairs, all controlled by a timer or photocell so it operates without daily attention.
Will lighting fixtures and wiring survive Arlington winters?
That's the standard we build to. We use fixtures and connections rated for outdoor exposure and freeze-thaw cycles, and we bury or route wiring so it isn't sitting exposed where mulching, edging, or frost heave can damage it. A system installed correctly the first time doesn't need a spring repair visit.
How many transformer zones does a typical Clarendon property need?
It depends on lot layout and fixture count, not a fixed number. A narrow Lyon Village lot with a single front walk may run on one transformer; a sloped Ashton Heights property with a retaining wall, rear patio, and multiple entries may need two zones to avoid voltage drop dimming fixtures at the end of a long run. We size transformers to the actual load during the site walk, not off a generic package.
Can lighting be added around mature trees without damaging roots?
Yes. Clarendon's tree canopy is part of what makes these blocks distinct, and we route wiring and stake fixtures to avoid trenching through major root zones. Uplighting a mature tree is typically a matter of careful fixture placement, not disruptive digging. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Do you install timers, or does someone have to turn the lights on every night?
We program timers or photocell sensors as part of the install so the system turns on at dusk and off on a set schedule automatically. No app required, no nightly switch-flipping — it runs on its own once we've set it. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Is outdoor lighting installation covered by warranty or a service call if something stops working?
We stand behind the install. If a fixture, connection, or transformer isn't performing as installed, call (703) 650-5655 and we'll address it. Discipline in the install is what prevents most callbacks in the first place. Our crews work Clarendon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
How much does outdoor lighting installation cost in Northern Virginia?
Most low-voltage landscape lighting projects run $2,500–$7,500, with a typical front-yard system of 12–20 fixtures landing around $3,500–$5,000 installed. Per-fixture pricing runs roughly $100–$200 depending on fixture type and wire-run length. Whole-property systems with multiple transformer zones can run $10,000 or more.
