Types of Outdoor Lighting to Install
Outdoor lighting comes in many forms, each serving a different purpose:
- Porch and entry lights: Wall-mounted fixtures that illuminate entry points and welcome guests
- Path lights: Low-level fixtures along walkways and driveways for safety and aesthetics
- Floodlights and security lights: High-output fixtures for perimeter security and large area illumination
- Motion-sensor lights: Automatically activate when triggered, deterring intruders and lighting your way
- Accent and landscape lights: Uplights, downlights, and spotlights highlighting trees, architecture, and garden features
- Post and driveway lights: Illuminate long driveways and mark property boundaries
How Outdoor Lighting Installation Works
Hardwired outdoor lighting connects to your home’s 120V electrical system. The process involves:
- Determining fixture locations and the routing for new wiring
- Running weatherproof cable through exterior walls, conduit, or underground where needed
- Installing GFCI-protected circuits as required by National Electrical Code (NEC) standards
- Mounting fixtures securely to exterior surfaces or in-ground posts
- Connecting to a switch, timer, or smart control inside the home

Outdoor Lighting Controls: Switches, Timers, and Smart Options
How you control outdoor lighting matters as much as the fixtures themselves:
- Wall switch: Simple and reliable; requires manual operation
- Timer: Automates on/off based on a set schedule; energy-efficient and convenient
- Photocell (dusk-to-dawn): Light-sensitive control that turns lights on at dusk and off at dawn automatically
- Motion sensor: Activates when movement is detected; ideal for security and entry lighting
- Smart switch/app control: Remote control, scheduling, and automation via smartphone or voice assistant
Wiring Requirements for Outdoor Lighting
All outdoor electrical wiring must meet specific code requirements: weatherproof cable (UF-B for direct burial or THWN in conduit), GFCI protection on all outdoor circuits, and weatherproof junction boxes and covers. A licensed electrician will ensure all materials and methods comply with your local electrical code.

When to Hire a Licensed Electrician
Any hardwired outdoor lighting installation requires a licensed electrician. This includes new fixtures, new circuits, underground wiring runs, and GFCI outlet installation. Working with outdoor electrical wiring exposes installers to weather-related hazards and requires specific materials and techniques to ensure long-term safety.
Frequently Asked Questions
Can I install outdoor lights myself?
Replacing an existing outdoor fixture with the same type (same wiring, same box) is a manageable DIY task for many homeowners. Any new wiring, new circuits, or underground runs require a licensed electrician and typically a permit.
What kind of wire is used for outdoor lighting?
Direct-burial outdoor wiring uses UF-B (underground feeder) cable, which is moisture-resistant and rated for direct burial without conduit. Above-ground outdoor wiring uses THWN or THWN-2 conductors in weatherproof conduit. Your electrician will select the correct material for each run.
How deep does outdoor wiring need to be buried?
Direct-burial UF-B cable must be buried at least 12 inches deep under general conditions. Wiring in conduit requires only 6 inches of cover. Under driveways and vehicle traffic areas, 24 inches of cover is required.
Do I need a permit to install outdoor lighting?
New hardwired outdoor lighting — particularly when new circuits or wiring runs are involved — typically requires a permit. Replacing an existing fixture on existing wiring may not. Your electrician can advise on local requirements.
