Streetlight

Sodium lights are fascinating because they are pretty much monochromatic: colour disappears when you look at an object under them, because if you illuminate an object with just one colour it can only reflect back that one colour. You can also use it to produce a spooky dark flame effect.

Something which emits a particular colour of light will also absorb it, so the edge of a sodium 'flame test' will look dark when illuminated by a sodium light producing a strange dark flame.

My streetlight includes a stand which makes it look like a real streetlight, and will fit in a standard 600x400mm footprint box. The light fitting may vary depending on availability.
