Advantage:





A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited



state to produce light. High-pressure sodium lamps have a broader spectrum



of light than the low pressure. High pressure sodium lamps are



quite efficient, about **0 lm per watt,



when measured forbistar lighting conditions. The higher powered versions



of **0 watt have an efficacy of even **0 lm per watt.

Application:





They have been widely used for outdoor area lighting such as streetlights



plant growth and security. Understanding the change in human color vision



sensitivity from photopic to mesopic and scotopic is essential for proper



planning when designing lighting for roads.
