Quick answer
The short answer
Line voltage (120V) outdoor lighting is best for security floodlights, soffit cans, and bright entry lights—it runs on standard household power and stays bright. Low voltage (12V) outdoor lighting is the standard for landscape paths and accent lighting—it’s safer to bury, easier to extend, and gentler on the eyes. Most homes use both.
What to know first
- Line voltage = bright, security-grade lighting.
- Low voltage = landscape, accent, path lighting—softer, safer, easier to add to.
- Low voltage requires a transformer; line voltage uses standard breakers.
When line voltage is the right call
Security lighting—motion-activated floodlights at corners of the house, bright entry lights at front and back doors, and any soffit or eave-mounted cans—runs on line voltage. You want brightness and reliability without adapter equipment to fail.
Line voltage also works well for fixtures that already have an exterior junction box installed during home construction.
When low voltage is the right call
Landscape lighting—path lights, well lights uplighting trees, deck lights, accent fixtures—almost always uses low voltage. The wiring is touch-safe, can be direct-buried at shallow depth, and is easy to extend if you want to add fixtures later.
A single transformer (typically 60–300W) powers a whole landscape kit. Most decent residential systems run on a single transformer with a photocell.
The smart compromise
Most well-designed outdoor lighting setups use both. Line voltage handles the security/utility lighting, and a low-voltage system layered on top adds atmosphere—path lights leading to the door, uplighting on the architecture, deck lights for evenings.
Line voltage vs low voltage outdoor lighting
Use this to pick the right system for each part of your property.
| Feature | Line voltage (120V) | Low voltage (12V) |
|---|---|---|
| Brightness | High—security and bright entry | Soft—accent and landscape |
| Wire requirements | Conduit-buried 18 in. minimum | Direct-bury 6 in. minimum |
| Transformer needed? | No | Yes (60–600W typical) |
| Best for | Floodlights, soffit cans, gates | Path lights, accent, deck/patio |
| Safety | Standard electrical risk | Touch-safe at the bulb level |

Frequently asked questions
Can I install low-voltage landscape lighting myself?
Yes—it’s relatively safe. The challenges are getting the transformer sized right, the layout balanced, and the fixtures durable enough to survive your climate.
Is low voltage really safer?
Yes—at 12V, you can touch the wires without injury. Line voltage outdoor wiring requires conduit-buried installation and is a real shock hazard if damaged.
How long do low-voltage transformers last?
Quality transformers last 15+ years outdoors. Cheap ones fail in 2–3.
Can I run lights from my outdoor outlet?
For temporary lighting, sure. For permanent installs, we usually run a dedicated circuit so seasonal outdoor outlet usage doesn’t share with permanent landscape.
