AJ Long Team Working

Transform your Northern Virginia property after dark with professional outdoor lighting designed for beauty, safety, and security. Our landscape lighting expertise covers complete system design using energy-efficient low-voltage LED systems operating at safe 12V power through buried transformers. We specify weather-rated fixtures with IP65 or higher ratings to withstand rain, snow, and humidity throughout the DC metro seasons. Every installation includes intelligent automation through photocell sensors that activate lights at dusk, programmable timers, and optional smart controls for app and voice operation. We design and install a full range of outdoor lighting including path lighting for walkways and driveways, uplighting and downlighting for trees and architectural features, security motion sensor floodlights, permanent holiday lighting systems along rooflines, deck and patio string lighting, and step and retaining wall accent lights. For homeowners concerned about light pollution, we offer dark sky compliant fixture options that direct light downward where it is needed. Our installations use direct-burial rated wiring and waterproof connectors, with all line-voltage work installed in proper conduit at code-required depths. From a single security light to a complete landscape lighting transformation, we deliver systems that enhance your home's curb appeal, deter intruders, and let you enjoy your outdoor spaces well into the evening.

Northern Virginia Service Context

Serving the DMV Region

Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties

Outdoor lighting is one of the most impactful home improvements for Northern Virginia properties, where homeowners invest significantly in landscaping and outdoor living spaces. The DC metro region's four distinct seasons mean outdoor lighting systems must withstand summer heat and humidity, fall leaf accumulation, winter ice and snow, and spring pollen -- all while performing reliably year-round. Northern Virginia's affluent communities like Great Falls, McLean, and Vienna feature large properties with mature landscaping that creates stunning opportunities for professional landscape lighting. Meanwhile, townhome communities throughout Reston, Ashburn, and Herndon benefit from targeted security and accent lighting that maximizes impact in compact spaces while complying with HOA guidelines. The region's emphasis on outdoor entertaining -- from spring patio dinners to fall football gatherings -- makes well-designed outdoor lighting a quality-of-life upgrade, not just a cosmetic one. Security is another major driver, as many Northern Virginia neighborhoods prioritize well-lit perimeters and motion-activated systems. AJ Long Electric designs outdoor lighting systems tailored to the specific property type, neighborhood context, and homeowner lifestyle, using weather-rated fixtures and direct-burial wiring methods proven to perform through every DC metro season.

Outdoor Lighting Case Studies

See how we have helped homeowners across Northern Virginia with their outdoor lighting needs.

Complete Landscape Lighting Transformation for Entertainer's Backyard

estate
Estate home in Great Falls, Fairfax County

Challenge

The homeowners had a professionally landscaped 1.5-acre property with mature trees, stone patios, and a pool, but zero outdoor lighting. They frequently entertained but guests struggled to navigate pathways after dark, and the stunning landscaping was invisible at night.

Solution

AJ Long Electric designed and installed a 32-fixture low-voltage LED landscape lighting system including path lights along all walkways, uplighting on 8 specimen trees, wash lighting on the stone facade, and deck string lights over the patio. A WiFi-enabled transformer allows app-based control and scheduling.

Result

The property is now as stunning at night as during the day. The homeowners extended their entertaining season and the well-lit pathways eliminated safety concerns for guests navigating the property after dark.

Security Lighting Package for Corner Lot Townhome

townhome
Townhome in Reston, Loudoun County

Challenge

A corner-lot townhome had three sides exposed to foot traffic and dark areas behind the garage and along the side yard. The homeowner had experienced package theft and wanted motion-activated security lighting, but the HOA restricted fixture styles visible from the street.

Solution

We installed four LED motion flood lights at strategic locations: two covering the driveway and front entry, one illuminating the side yard, and one covering the rear patio. All fixtures were selected from the HOA-approved fixture list. We added a dusk-to-dawn photocell on the front porch light for constant low-level illumination.

Result

Package theft stopped immediately after installation, and the homeowner reports feeling much safer arriving home at night. The HOA-compliant fixtures blend seamlessly with the community aesthetic.

Dark Walkway and Driveway Illumination

colonial
Colonial home in Vienna, Arlington County

Challenge

An elderly couple in a classic Vienna colonial had a long, winding front walkway and a 60-foot driveway that were completely dark after sunset. The husband had tripped on the walkway steps twice, and delivering guests could not find the front door at night.

Solution

We installed 14 low-voltage LED path lights along the walkway and driveway, with step lights integrated into the front porch stairs. Two bollard lights flank the front entry, and a photocell activates the entire system automatically at dusk. All wiring was buried beneath existing mulch beds.

Result

The walkway and driveway are now safely illuminated every evening without the homeowners touching a switch. The path lights also dramatically improved the home's curb appeal, and neighbors have requested similar installations.

Permanent Holiday Lighting and Accent System

split-level
Split-level in Centreville, Prince William County

Challenge

The homeowner spent every November on a ladder hanging holiday lights along the roofline and gutters of their split-level home, a process that took a full weekend and involved working at heights up to 25 feet. After a near-fall, they wanted a permanent solution.

Solution

AJ Long Electric installed a permanent LED strip lighting system along all rooflines and gutters using commercial-grade IP67-rated RGB strips in aluminum channels. The system connects to a smart controller that can display holiday colors, everyday accent lighting, or patriotic themes on demand.

Result

The homeowner now changes their home's lighting theme from their phone in seconds. They have not touched a ladder since installation and estimate they have reclaimed two full weekends per year previously spent on holiday light installation and removal.

By Home Type

Outdoor Lighting by Housing Type

Different home styles have unique electrical characteristics. Select your housing type to see specific considerations.

Colonial Homes

Common Issues

Traditional facades benefit from symmetrical uplighting and wash lighting
Mature landscaping around established colonials creates complex lighting design needs
Long driveways typical of older colonials require extensive path lighting runs
Brick and stone facades need fixtures with sufficient output for proper illumination

Special Considerations

Colonial homes in McLean, Vienna, and Fairfax often sit on larger lots with mature trees and established landscaping that benefit from carefully designed uplighting and path lighting. The traditional architecture pairs well with warm-toned (2700K) fixtures in classic lantern styles. We design symmetrical lighting layouts that complement the balanced proportions characteristic of colonial architecture.

FAQs

Frequently Asked Questions

Get answers to common questions about our outdoor lighting services.

What is the difference between line-voltage and low-voltage outdoor lighting?

Line-voltage lighting runs on standard 120V power and requires conduit and deeper burial for safety. Low-voltage systems use a transformer to reduce power to 12V, making them safer to install, more energy-efficient, and easier to modify. We recommend low-voltage for most landscape lighting.

How should I light my front walkway and entry?

Path lights every 6-8 feet provide safe navigation without creating runway-style rows. Uplighting or downlighting at the front door creates a welcoming entry. We design layouts that balance safety, aesthetics, and preventing light pollution into neighbor properties.

Can outdoor lighting be integrated with smart home systems?

Yes, we install smart outdoor lighting controls including timers, photocells (dusk-to-dawn sensors), and WiFi-enabled transformers. Low-voltage landscape lighting can be controlled by app or voice, and motion sensors can trigger alerts or recordings from security cameras.

How do you protect outdoor wiring from damage?

Low-voltage wiring is buried 3-6 inches deep, which is adequate for safety and easy future access. Line-voltage outdoor circuits are run in weatherproof conduit and buried to code-required depths (typically 18-24 inches). We use silicone-filled wire connectors that prevent moisture intrusion.

What outdoor lighting is best for security?

Motion-activated floodlights deter intruders and alert you to activity. We position lights to eliminate dark corners and blind spots without creating harsh glare. Wall packs, soffit lights, and well-placed landscape lights create a perimeter of visibility that makes homes less attractive to criminals.

Can you install permanent holiday lighting?

Yes, we install permanent LED strip lighting systems along rooflines that can be programmed for holiday colors, everyday accent lighting, or security purposes. These systems eliminate the annual hassle of hanging and storing lights and are professionally installed for a clean appearance.

How do outdoor outlets differ from indoor outlets?

Outdoor outlets must be weather-resistant (WR) rated and installed in weatherproof in-use covers that protect them even when a cord is plugged in. They require GFCI protection for safety around moisture. We install outdoor outlets for string lights, fountains, or holiday decorations.

What is the difference between LED and halogen landscape lights?

LED landscape lights use up to 80% less energy than halogen, last 25,000+ hours versus 2,000-4,000 hours for halogen, and produce far less heat. LEDs are available in a wide range of color temperatures and are now the industry standard. We recommend LED for all new installations and can retrofit existing halogen systems.

Can outdoor lighting increase home security?

Absolutely. Well-designed outdoor lighting is one of the most effective crime deterrents. Motion-activated floodlights alert you to activity, while consistently lit perimeters eliminate hiding spots. Studies show that homes with exterior lighting are significantly less likely to be targeted by burglars. We design security lighting layouts that maximize coverage.

How deep do you bury outdoor wiring?

Burial depth depends on the wire type. Low-voltage landscape wiring is buried 6 inches deep, which is safe and allows easy future access for modifications. Line-voltage wiring in conduit must be buried 18 inches deep per NEC requirements. We follow all code-required burial depths and mark wire locations for future reference.

Can I add lighting to existing landscape beds without tearing them up?

Yes, low-voltage landscape lighting is designed for easy installation in existing beds. The small-gauge wire can be tucked along bed edges and buried with minimal disruption. Fixtures mount on simple stakes pushed into the soil. We carefully work around existing plants and restore mulch after installation.

What are dark sky compliant fixtures?

Dark sky compliant fixtures are designed to minimize light pollution by directing light downward rather than allowing it to scatter upward or sideways. They reduce glare, protect nighttime ecosystems, and are increasingly required or preferred in Northern Virginia communities. We offer dark sky options for all our landscape and security lighting installations.
