I am forming a list of light sources that uses electricity. It should be in date order when it came first. Like carbon arc is first (I think) going to the latest invention of electric lights. Thanks.

i think this is a partial list that is in order...but im not too sure...the information came from a wide variety of Sources..hope this helps a little.


1.Carbon Arc-1801
2.Incandescent-1879(First bulb that could burn up to 40 hours)
3.Flourescent-1896
4.Mercury Vapor-1934
5.Sodium Vapor-1963
6.Metal Halide late 50's-Mid 60's

Do you have info on low pressure sodium?

Lamptech says 1932 was when the first LPS lamp was put out in production..
