Sodium Vapor

The light from these street lamps makes it almost impossible to tell what the original color of an object is.

The type of lamp used here is a sodium vapor lamp of which there are two types;

• Low-pressure

• High-pressure

Low pressure sodium vapor lamps, as seen in this panorama, generate a charactaristic orange/yellow light. This light is nearly monochromatic with a wavelength of 589.0-589.6 nm. It is this very narrow spectral bandwidth that makes it difficult to distinguish colors.
These lamps are usually preferred in coastal areas due to their ability to penetrate fog better than white light. They are also used where light-pollution is a concern (like near observatories) as the light can easily be filtered out.

High-pressure sodium vapor lamps have a pinkish-yellow color, and produce light across the spectrum, and are used where color rendition is important.

I can kick myself silly for not have taken some extra shots with a faster shutter-speed so that you could have seen a better definition of the lamps instead of yellow blobs. aaargh...
