Most pathway lighting systems will have recommended spacing values to ensure optimal performance. For example, bollard-style lights are typically set 3-4 feet apart, while in-ground lamps are usually spaced 10-12 feet apart. Ultimately, the best spacing for your particular system will depend on the intensity and distribution of light desired. Consult your lighting manufacturer or supplier for specific guidance on choosing the right spacing for your needs.
