Lighting Infrastructure You Can Trust
Lighting plays a crucial role in the safety, functionality, and visual appeal of any development—whether it’s a quiet residential street, a bustling commercial plaza, or a city-owned roadway. At Windsor Underground, we specialize in installing durable, code-compliant streetlight and site lighting systems that align seamlessly with broader dry utility infrastructure. Our services include everything from trenching and conduit placement to pole base installation and electrical wiring, all performed with strict adherence to safety and design standards. With decades of experience and deep utility knowledge, we ensure that each lighting system enhances visibility, public safety, and long-term infrastructure integrity.
We work in close collaboration with general contractors, land developers, municipal engineers, and utility providers to meet complex lighting design specifications and site constraints. From navigating permitting requirements to managing trench layouts and fixture schedules, we ensure every project phase is handled with precision and accountability. Our team coordinates with APS, SRP, and local authorities to secure timely inspections and approvals, and we manage load calculations to verify that installed systems meet both operational and energy efficiency standards. Whether lighting a large subdivision or retrofitting lighting in a commercial parking lot, we deliver complete, energized systems built for long-term reliability.
Smart Lighting Installations For Every Environment
Streetlight and site lighting infrastructure is not just functional—it’s regulated and closely monitored. We ensure every base, conduit, and pull box is installed to spec and aligned with utility and city standards. Whether building a subdivision or lighting a public park, our focus is on longevity, performance, and efficiency.

Windsor Underground installed a complete streetlight conduit system and pole bases for a 120-lot residential development. The project required trenching, conduit runs, and base placement to accommodate multiple fixture types approved by APS. We worked closely with the utility provider to ensure layout compliance and scheduling for energization. Final trench restoration and inspection were completed in accordance with city standards.

For a busy retail plaza, Windsor Underground installed LED pole lighting to enhance parking lot safety and visibility. Our scope included pull box and riser installations, load balancing across circuits, and night-time system testing to ensure operational accuracy. All lighting infrastructure was connected to pre-planned utility feeds and installed to meet commercial code. The energized system was delivered ready for final tenant occupancy.

We completed a decorative, low-voltage lighting installation across a city-owned trailhead and recreational park. This project involved directional boring beneath pathways, vault setups, and the use of specialized light fixtures that met city aesthetics and safety standards. All work was executed with minimal disturbance to public spaces and completed with full city inspection and approval. The result was a safe, welcoming environment for community use after dark.
