The following links concern issues in low-pressure sodium lighting. Readers aware of other information, particularly reliable information documenting any of the many serious claims often heard against LPS*, are encouraged to contact the author. Reliable information of any type will be added to the links below; anecdotal information will not.

This page is under development and will remain so for some time.

* Serious claims made: lack of acceptance by the public; difficulty in crime investigation because of witness' inability to accurately describe colors; fires caused by improper lamp disposal; compromise in emergency medical care due to inability to distinguish blood from oil at an accident scene; lower lamp lifetimes than listed in manufacturer's data; legal liability due to insufficient lighting level caused by poor scotopic visibility.
