For both indoor and outdoor lighting, there are four major categories: ambient lighting, accent lighting, decorative lighting, and task lighting. Ambient lighting outdoors is focused on improvising visibility and illumination. Examples include wall-mounted lighting, lanterns, and path lights. Accent lighting simply highlights a small area of features- such as a porch swing or a small garden. Decorative lighting is something like string lights, which add just touches of light but are mostly focused on adding style and ambiance. Finally, task lighting outdoors would be something like floodlights and security lights: not selected as much for ambiance, but more for a specific objective (such as adding security).
