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 100 lm per watt,
when measured for Bistar lighting conditions. The higher powered versions
of 600 watt have an efficacy of even 150 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.
