For protection purposes, I use a convex clock glass in a filter holder. It eliminates the ghosts at the expense of a slight loss of quality. I seem to remember in the good old 1960s you could buy convex 1A (uv) filters, or did I imagine it. Or remove filter and risk your lens!

Working from the Sunny 16, it is four stops between f/4 and f/16: 4 - 5.6 - 8 - 11 - 16 Assuming an ISO of 100, 1/100th of a second to two minutes is 14 stops 1/100 - 1/60 - 1/30 - 1/15 - 1/8 - 1/4 - 1/2 - 1 second - 2 - 4 - 8 - 15 - 30 - 1 minute - 2 minutes. Together, this will suggest you would need about 18 stops of density to get a 2 minute ...

Sodium vapor lights lamps come in two types - there is the low pressure which is nearly yellow (589.0 nm and 589.6nm) and the high pressure which produces a more pinkish tone which has a few other elements doping it and resulting in a more 'natural' color rendition. The low pressure one is trivial to filter out with a common filter for photography, and the ...

As the answers there explain, sodium vapor lights produce a very, very narrow spectrum of light: CC-BY-SA image from Wikimedia Commons, author Philips Lighting And in fact, this is effectively monochrome. Your only options ...

Light is composed of many wavelengths even when one is predominant such as in street lighting, thus I doubt a filter will work very well. Try wrapping a black bag around the street light or finding some other way to block the light. Light painting at night relies upon overpowering the ambient light with the lighting used. So you will need to experiment with ...
