Security Lighting Guide: Best Outdoor Lights to Deter Intruders

Well-placed outdoor lighting is one of the most cost-effective security upgrades you can make. It deters burglars, eliminates hiding spots, and dramatically improves security camera footage. But bad lighting creates blind spots and a false sense of security. Here is how to do it right.

Types of Security Lighting

💡

Motion-Activated Floodlights

Turn on when motion is detected (PIR sensor). Best for driveways, side yards, and back doors. Energy-efficient since they only run when triggered. Look for adjustable sensitivity and range (15 to 70 feet typical).

Dusk-to-Dawn Lights

Stay on all night using a photocell sensor. Best for front entries, porches, and walkways where constant illumination provides both security and convenience. Use LED bulbs to keep energy costs low (3 to 10 watts).

Solar-Powered Lights

No wiring needed. Ideal for fences, paths, and areas far from outlets. Performance depends on sun exposure. Best solar lights (Ring Solar Floodlight, LITOM) deliver 800 to 2,000 lumens. Weaker models under 400 lumens are decoration, not security.

Smart/Connected Lights

Control via app, set schedules, integrate with cameras. Ring Floodlight Cam and similar combine lighting with recording. Useful for triggering lights from inside when you hear something outside. Require WiFi.

Where to Place Security Lights

1

All Entry Points

Front door, back door, side doors, and garage doors. Every exterior door should be illuminated. Use dusk-to-dawn lights at the front door and motion-activated at less-trafficked entries.

2

Driveway and Walkways

Motion-activated floodlights at the garage and driveway entrance. Path lights along walkways serve double duty for safety (preventing falls) and security (eliminating approach cover).

3

Side Yards and Fence Lines

These are the most common burglar entry points because they are typically dark and out of view. Motion-activated lights with 180-degree detection cover the full area. Mount at 8 to 10 feet to prevent tampering.

4

Near Security Cameras

Cameras need light to capture usable footage. Mount lights to illuminate the camera's field of view without shining directly into the lens (which causes glare and washed-out video). Position lights above or beside cameras, angled downward.

💡
The biggest lighting mistake: dark spots next to bright areas. A single bright floodlight creates harsh shadows that actually provide better hiding spots. Use multiple moderate lights to create even illumination across the entire perimeter. Overlap coverage areas.

Brightness Guide

LED bulbs pay for themselves in months. A 20W LED floodlight produces the same output as a 150W halogen and costs about $3 per year to run at 8 hours per night. Replace any remaining halogen or incandescent security lights with LEDs immediately.
