Low-pressure sodium-vapor lamps are extremely efficient. They produce a deep yellow-orange light and have an effective CRI of nearly zero; items viewed under their light appear monochromatic. This makes them particularly effective as photographic safelights. High-pressure sodium lamps tend to produce a much whiter light, but still with a ...
High-pressure lamps have a discharge that takes place in gas under slightly less to greater than atmospheric pressure. For example, a high pressure sodium lamp has an arc tube under 100 to 200 torr pressure, about 14% to 28% of atmospheric pressure; some automotive HID headlamps have up to 50 bar or fifty times atmospheric pressure.
In 1980, the annual operating cost for the average incandescent lamp was $280; for mercury vapor lamps, it was $128; and for low-pressure sodium vapor lamps, it was $60 a year. [1] Meanwhile, high-pressure sodium vapor lamps cost only $44 a year to operate, with a standard life expectancy of 15,000 hours, which also helped to lower labor and ...
