Outdoor Lighting 101 by Craig DiLouie

Outdoor stationary lighting presents a substantial market and a distinctive subset of lighting design. While the market covers a variety of applications, the largest are building exterior and area and roadway lighting. In a typical indoor space lighted during the day, the ceiling is relatively bright, the light is localized and has little or no impact on the natural environment, and the eye uses photopic vision. With outdoor lighting, the “ceiling” is relatively dark, unshielded lighting may be visible at great distances and impact the environment, and the eye may use scotopic vision (dark conditions) or mesopic vision (semi-dark). Generally, the primary goals are to enable nighttime business, leisure, and enjoyment while promoting safety and security. http://www.lightnowblog.com/
