When it comes to outdoor security lights, there are a few types that dominate the marketplace because they deliver the most security and value. To help you figure out which one is best for you, we break down the most common types below. Motion sensor lights Motion sensor lights do exactly what their name implies—they detect motion and light up to either get you safely to the door or scare off an intruder. This is a valuable feature to have in an outdoor security light because you know it’s doing its job even when you’re away from home or fast asleep. Floodlights Floodlights are useful for outdoor security because of their broad beam and high-intensity illumination. These lights are meant to literally “flood” an area with light. They’re an excellent choice for large yards and fields. They also provide superbright illumination in areas like garages or sheds where you may need some extra light after the sun sets. Spotlights Almost the opposite of floodlights, spotlights project a narrow, focused beam of light directly onto one area. Most of the spotlights on our list have multiple heads so that you can shine a narrow beam in various directions at once. Spotlights are a good choice to help light up a door or pathway for safe passage (and entry) after the sun sets.
