What to Know Before Hiring Outdoor Landscape Lighting Companies in Pennsylvania
Hiring a landscape lighting company is a different decision from hiring a general landscaper or electrician. The best outdoor lighting results come from contractors who specialize exclusively — or primarily — in low voltage outdoor landscape lighting systems. They understand fixture placement for visual effect, lumen output by application, transformer sizing, wire management, and the long-term maintenance needs of an outdoor lighting system exposed to Pennsylvania’s full four-season climate.
Outdoor landscape lighting companies in Pennsylvania operate across a wide range of service levels. Some offer basic fixture installation with off-the-shelf components. Others provide full-service landscape lighting design, custom fixture specification, professional-grade LED landscape lights, and multi-year maintenance contracts. Understanding what separates these tiers — and knowing which one your project actually needs — is the foundation of a hiring decision you won’t regret. For a structured approach to evaluating vendors, review our guide on how to find reliable landscape lighting contractors.
This guide walks you through the full evaluation process: what credentials to verify, what a professional installation actually includes, how to compare quotes, and what red flags to watch for before you sign anything.
Why Pennsylvania Homeowners Need Specialist Landscape Lighting Contractors
Pennsylvania’s climate presents specific challenges for outdoor lighting systems that general landscapers often underestimate. Freeze-thaw cycles through central and northern Pennsylvania can shift ground-mounted fixtures, stress buried wire connections, and compromise transformer mounting hardware over time. Summer humidity in the Philadelphia suburbs and Pittsburgh metro areas accelerates corrosion at wire connectors and fixture housing seals.
A contractor who installs systems in Florida or the Southwest may have excellent design skills but limited experience with the maintenance demands of a mid-Atlantic climate. Specialist landscape lighting contractors in Pennsylvania — particularly those who hold certifications from the Association of Outdoor Lighting Professionals directory or manufacturer-specific training programs — are trained to specify weatherproof components, weatherproof wiring connectors, and transformer placements that account for local seasonal conditions. This is not a minor distinction.
A system installed correctly for Pennsylvania’s climate will outlast one installed to generic standards by years. For seasonal preparation strategies tailored to the region, see our guide on winter landscape lighting safety and maintenance. Beyond climate, Pennsylvania’s residential landscape character varies significantly by region.
The historic stone properties of Chester County, the wooded suburban lots of Montgomery and Bucks Counties, the traditional architecture of Pittsburgh’s North Shore neighborhoods, and the modern construction of the Lehigh Valley all call for different landscape lighting design approaches, fixture styles, and placement strategies. A company with a strong local portfolio across Pennsylvania’s regional character is a meaningful asset.
What a Professional Landscape Lighting Installation Includes
Before comparing companies, understand what a complete professional installation should deliver. Many homeowners receive quotes that look competitive on paper but are missing critical components. Here is what a full-service outdoor landscape lighting installation covers:
Site Assessment and Design
A professional company begins with a thorough site assessment — walking the property at night if possible, identifying key features for professional tree uplighting techniques, accent placement for garden areas, pathway light placement and spacing guidelines, and entry point lighting.
From this assessment they produce a landscape lighting design plan showing fixture positions, wire run paths, zone assignments, and transformer location. This design phase is not optional. It is the difference between a system that looks intentional and one that looks like fixtures were placed wherever the installer found convenient. Companies that skip the design phase and go straight to installation are not providing professional landscape lighting service — they are providing fixture placement.
Fixture Specification
A professional company specifies fixtures by application — matching lumen output, beam angle, and housing type to each position in the design. Pathway landscape lights, garden lighting fixtures, uplights, step lights, and wall wash fixtures all require different specifications. A company that uses identical fixtures across an entire system regardless of application does not understand landscape lighting design. Reputable companies specify LED landscape lights as standard across all new installations. LED fixtures deliver equivalent or superior lumen output to halogen at a fraction of the energy draw and last ten times longer — a significant advantage for the homeowner’s long-term maintenance cost, as validated by U.S. Department of Energy LED performance research.
Transformer Selection and Installation
A professional installer selects and properly installs a landscape lighting transformer sized to at least 120% of the system’s total fixture wattage. The transformer should be mounted at the correct height on a weatherproof surface, connected to a GFCI-protected outdoor outlet, and configured with accurate timer or photocell settings before the installation is considered complete. A company that leaves transformer sizing to the homeowner or installs a unit that operates at or above 100% capacity is cutting a corner that will cost you in premature failures and fixture inconsistency. Always verify proper load planning with a landscape lighting transformer sizing guide.
Wire Installation and Burial
All wire runs should use outdoor-rated direct burial cable buried to the depth required by the National Electrical Code (NEC) — a minimum of 6 inches for low voltage systems, 8 inches in high-traffic or lawn maintenance zones. Wire connections at each fixture should use weatherproof gel-filled or heat-shrink connectors. Any company using standard indoor wire nuts for outdoor connections is not following safe or durable installation practices. Always confirm contractors adhere to National Electrical Code low-voltage requirements for burial depth and weatherproof connections.
Testing, Adjustment, and Walkthrough
A complete installation ends with a full system test after dark, voltage verification at the farthest fixture from the transformer, and a walkthrough with the homeowner to confirm fixture angles, coverage, and timer settings. Some companies include a follow-up adjustment visit 30 days after installation — this is a mark of quality service because fixture positions often benefit from fine-tuning once the homeowner has lived with the system through a full week of evening use.
Step-by-Step: How to Evaluate and Hire a Landscape Lighting Company in Pennsylvania
Step 1 — Define your project scope before making any calls.
Know roughly how many zones you want to light, which features matter most — pathway coverage, uplighting, entry lighting, security — and whether you want a full design service or a straightforward installation of a pre-planned layout.
Step 2 — Search for specialists, not generalists.
Look specifically for companies that list landscape lighting as a primary service, not a secondary add-on to lawn care or general landscaping. Check for AOLP certification or manufacturer training credentials from brands like Kichler, FX Luminaire, or Vista Professional Outdoor Lighting.
Step 3 — Request portfolios with Pennsylvania projects.
Ask to see completed installations from local Pennsylvania properties — ideally in your region of the state and in a similar architectural style to your home. A strong local portfolio demonstrates both design skill and climate-appropriate installation practices.
Step 4 — Get a minimum of three written quotes.
Quotes should specify fixture count and model numbers, wire gauge and burial depth, transformer make and wattage rating, number of zones, warranty terms on both fixtures and labor, and what the post-installation service process looks like. Use an outdoor landscape lighting installation cost guide to understand exactly which line items should appear before comparing bids.
Step 5 — Verify licensing and insurance.
In Pennsylvania, low voltage landscape lighting installation does not always require a full electrical contractor license — but the company should carry general liability insurance and workers’ compensation coverage. Ask for certificates of insurance and verify them directly with the issuing carrier.
Step 6 — Ask the right questions.
Key questions to ask every company: Do you perform a site assessment before quoting? Do you use LED landscape lights as standard? What transformer brand and wattage will you install? How deep will wire be buried? What is your warranty on labor and fixtures? Do you offer annual maintenance contracts?
Step 7 — Compare quotes on value, not price alone.
The lowest quote is rarely the best value in landscape lighting. A company that specifies commercial-grade LED fixtures, proper transformer sizing, and weatherproof connections will cost more upfront and save significantly in replacements and repairs over a five to ten year system lifespan.
DIY Low Voltage Kits vs. Professional Installation: Which Is Right for You?
| Factor | DIY Low Voltage Lighting Kits | Professional Landscape Lighting Installation |
|---|---|---|
| Upfront cost | Low ($50–$300 for basic kits) | Higher ($1,500–$10,000+ depending on scope) |
| Design quality | Limited — kit fixtures, fixed spacing | Custom — designed for your specific property |
| Fixture quality | Consumer grade | Professional or commercial grade LED |
| Transformer sizing | Kit-included (often undersized) | Properly sized with buffer capacity |
| Installation time | 2–4 hours DIY | Full day or multi-day professional install |
| System expandability | Limited | Designed for future expansion |
| Climate durability | Variable — connector quality often low | High — weatherproof components specified |
| Warranty coverage | Manufacturer only | Labor + fixture warranty from contractor |
| Long-term value | Lower | Higher |
| Best for | Small yards, budget installs, renters | Permanent homes, large properties, quality-focused buyers |
If you need a simple solution for a small rental property or a seasonal accent lighting display, a low voltage landscape lighting kit is a practical and affordable starting point. If you own your home, care about visual quality, and want a system that performs reliably through Pennsylvania winters and summers for a decade or more, professional installation delivers a return that DIY kits cannot match.

Hiring a Lighting Company for a Chester County Property
A homeowner in Chester County, Pennsylvania had a 3/4-acre property with a stone farmhouse-style exterior, mature oak trees along the driveway, and a formal garden behind the home. After getting quotes from three companies, they received bids ranging from $2,800 to $7,400. The lowest bid came from a general landscaping company offering a standard low voltage landscape lighting kit installation with 12 identical fixtures across all zones. No design plan was provided upfront, and the quote did not specify transformer wattage or wire gauge.
The middle bid came from a specialist outdoor lighting company with AOLP certification. Their quote included a full landscape lighting design plan, 18 LED fixtures across four zones — driveway uplighting for trees, pathway landscape lights along the entry walk, garden lighting fixtures in the rear formal garden, and step lights at the entry — plus a properly sized 300W transformer with a 20% capacity buffer. Wire was specified at 12 AWG direct burial, buried to 8 inches throughout.
The homeowner chose the specialist company. The finished system used 62W of power across all 18 LED fixtures, operated on a photocell timer, and required zero maintenance calls in the first two years of operation. The oak tree uplights and formal garden accents created a visual effect that the homeowner described as transforming how the property felt after dark in a way the budget kit quote could never have delivered. To replicate this tier of results, explore professional landscape lighting design services that map every fixture to your property’s architecture.

Glossary of Terms
Association of Outdoor Lighting Professionals (AOLP) The primary professional trade organization for the outdoor lighting industry in North America. AOLP certification indicates that a landscape lighting contractor has met defined standards of technical knowledge, professional practice, and continuing education in outdoor lighting design and installation.
Low Voltage Landscape Lighting An outdoor lighting system that operates on 12V current, converted from standard 120V household power by a transformer. Low voltage systems are safe for DIY handling, widely used in residential landscape lighting design, and the standard platform for LED landscape lights across Pennsylvania and the broader United States.
Landscape Lighting Transformer A device that converts 120V household current to the 12V output required by low voltage outdoor lighting systems. Sized in watts, it determines how many fixtures the system can power simultaneously. Professional installers size transformers to at least 120% of the total fixture wattage load.
Photocell A light-sensitive sensor installed on a landscape lighting transformer that automatically activates the system at dusk and deactivates it at dawn. Photocells eliminate the need for manual timer adjustments as daylight hours change through Pennsylvania’s four seasons.
