Low intensity discharge lamps operation
WebA low-pressure sodium lamp is a type of lamp that produces light from sodium gas contained in a bulb operating at a partial pressure of 0.13 to 1.3 pascal. Low-pressure sodium lamps provide energy-efficient outdoor lighting compared to high-intensity discharge lighting, but they have a very low color rendition index.
