How this works: Highlands Ranch Lighting is a free referral service, not a lighting contractor. We pass your request to independent local lighting installers, who may pay us for the referral. They quote, schedule and do the work; check their insurance before you hire. More about us.
What a system includes
MSI Mechanical, a Lone Tree installer, describes the standard residential approach: a transformer steps 120V household power down to 12V, and low-voltage cable runs to the fixtures and "can be safely buried at shallow depth." A basic system in its price list is 8-12 fixtures with a transformer and a control (timer or photocell).
MSI says basic installs typically take 1-2 days and larger systems 3-5 days, and that working around existing plants takes a little longer than lighting a yard during landscape construction.
What it costs
| System size | Angi 2026 | Local installer pages |
|---|---|---|
| Small, 4-8 fixtures | $800 to $2,000 | Denver Landscape Lighting: simple entry lighting from about $1,000 |
| Medium, 9-16 fixtures | $2,000 to $4,500 | MSI: basic 8-12 fixtures $1,500 to $3,500 |
| Large, 17+ fixtures | $4,500 to $10,000 | MSI: comprehensive $3,500 to $8,000; Lighthouse: most projects $8,000 to $20,000 |
Angi's 2026 average is $3,500, with most homeowners paying $2,000 to $6,000. Per fixture, Angi lists path lights at $100 to $250 and spotlights at $150 to $350 installed. Full breakdown in the cost guide.
Approval before you dig
In Highlands Ranch, the HRCA's guidelines say ARC approval is required for new or replacement exterior fixtures, "including decorative, security, landscaping and accent, and permanent eave/trim", and that landscape and accent fixtures "Must be low voltage and integrated into landscape plan." Other towns set their own limits; see dark-sky and HOA lighting rules.
Before any trenching, Colorado 811 says calling or clicking at least three business days ahead is the law and the service is free. It marks public utility lines, not private ones like an existing lighting run or sprinkler lines.
What to ask each installer
- How many fixtures, of which types, and where (ask for a drawing).
- Transformer size and how much spare capacity it leaves for adding lights later.
- Color temperature and lumens per fixture, and whether that meets your HOA and town limits.
- Who prepares the HOA submittal and who calls 811.
- Warranty on fixtures and on labor, in writing.
Questions people ask
Do I need a permit for low-voltage landscape lighting?
It depends on the town and the wiring. Douglas County's electrical permit application lists "Low Voltage Wiring" as a permit category, and a new outdoor outlet for the transformer is line-voltage work. Ask the installer who pulls any permit, and check your HOA first.
How long does installation take?
MSI Mechanical in Lone Tree says basic installations typically take 1-2 days and larger systems 3-5 days.
