Dan,
Yes, those were my thoughts. She would first have to buy one and then be
able to identify the spectrum. If it was me and I had no knowledge about
light and spectra, I would not be inclined to do this. Also, what if
things get complicated by a small lamp in the fixture to give better
color rendition? Since this is a park, would not the park administrative
office know? Or maybe the city still has the permits on record she could
review. I believe this is public information.
