Re: [APML] street light spectra

Thank you Don, but it is not as easy as you might think to find the data.

Before sending my post I´ve spent some time surfing in "darksky" webs and lamp manufacturers sites

with no result. I´ve only found some general comments on which parts of the

spectrum are more affected with the different type of lamps, but I am looking for a much

more detailed information.

Subject: [APML] street light spectra

I am looking for detailed spectra of commercial lamps employed
in street lights: mercury vapor and sodium vapor (low & high pressure).

Does anybody know any internet sources regarding this subject ?
