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 for photonic 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.
