GE Form M2 
GE Type M2 low pressure sodium fixture on display at the Golden Gate Bridge Southeast Visitor Area. These fixtures were originally used on the Golden Gate and Oakland Bay bridges. In 1972, the original M2 fixtures on the Golden Gate Bridge were replaced with shoebox type high pressure sodium fixtures.

This one has been converted to use a modern 35 watt SOX from its original 180 watt GE NA-9 sodium lamp which have not been made since 1966
