[RFI] Mercury and Sodium street lite spectra??

[wa2bpe at infoblvd.net (WA2BPE)]

Folks,

Anybody have an idea where to find the optical spectra for Mercury and
Sodium steet/safety lights?  Several searches have not been fruitful -
perhaps I am not picking the right search terms.  The purpose of this is
to find suitable filtering for a Laser communication system.

TIA,
