Talk:Spectral G-index

A fact from Spectral G-index appeared on Wikipedia's Main Page in the Did you know column on 8 April 2019 (check views). The text of the entry was as follows:

Did you know... that the European Commission's Joint Research Centre recommends using the spectral G-index rather than correlated color temperature to select streetlights that have low blue light content?

A record of the entry may be seen at Wikipedia:Recent additions/2019/April. The nomination discussion and review may be seen at Template:Did you know nominations/Spectral G-index.

Citation for g-index and light pollution

Flibirigit added a "citation needed" after the lines: "The G-index does not directly measure light pollution, but rather says something about the color of light coming from a lamp. For example, if twice as many lamps are used, the G-index would not change, because it is a measure of fractional light, not total light. Similarly, the G-index is not related to the direction in which a lamp shines, so it is not directly related to skyglow."

I'm not sure to which fact the "citation needed" was referring, but these facts are all logical consequences of the equation itself. Therefore, I do not believe that a citation is required. I changed the text to make this more clear. I also added a citation for the fact that skyglow depends on the direction light is shining. Anotherdoon (talk) 14:49, 8 March 2019 (UTC)[reply]
