Architectural landscape lighting in Castle Rock and Parker — extending your outdoor living into the evening and highlighting your property's best features.
Landscape lighting transforms your property after the sun goes down. It extends the usability of your outdoor spaces, highlights architectural and landscape features, improves safety and security, and creates ambiance that simply doesn't exist during the day.
Ground Theory designs and installs low-voltage LED lighting systems that are energy-efficient, long-lasting, and beautifully engineered. We think in layers — path lighting for safety, accent lighting for features, uplighting for trees and architecture, and ambient lighting for gathering spaces.
The result is a property that looks intentional and inviting after dark — not a few random lights scattered around the yard, but a cohesive lighting design that enhances everything you've built.

Layered lighting plans — path, accent, uplight, downlight, and ambient — designed to enhance your property's best features.
Low-level path lights that guide movement safely and define walkways after dark.
Uplights that highlight trees, structural elements, and architectural features with dramatic effect.
Subtle lighting in gathering spaces that extends outdoor living into the evening hours.
Energy-efficient, long-lasting LED fixtures and bulbs that minimize power consumption and maintenance.
Properly sized transformers, photocells, timers, and smart controls for reliable, automated operation.
A beautiful landscape that disappears after dark is only half-finished. Quality landscape lighting extends your outdoor living, improves safety and security, and creates a completely different — and often more dramatic — experience of your property after sunset.
Ground Theory proudly provides landscape lighting services to homeowners and commercial properties across the southern Denver metro and Front Range communities.
LED is the clear choice today. LED fixtures use a fraction of the energy, last much longer, and produce less heat. While the initial investment is slightly higher, the long-term savings on energy and bulb replacement make LED far more cost-effective — and the light quality has improved dramatically.
Cost depends on the number of fixtures, system complexity, and transformer requirements. A typical residential lighting installation in Castle Rock ranges from $3,000–$10,000 depending on scope. We provide detailed proposals with fixture types, quantities, and layout.
Yes — if the system is designed with expansion in mind. We size transformers with capacity for future additions and design the layout to accommodate growth. It's always better to start with a well-designed core system and expand over time than to add fixtures randomly.
