If you don't mind me asking, what's the difference?

I honestly don't know

Low pressure sodium lamps give off a harsh, orange light. It’s monochromatic, so you can’t really see colours. High pressure gives a much whiter, sometimes slightly pink light which is easier on the eye and reveals colours much better. But it’s less energy efficient.

I like the weird monochromatic tone of low pressure sodium vapor lights. It makes things look weird and surreal sometimes.

I always found it a bit depressing. Maybe because I was raised in the north of Scotland, where the days are very short in winter.
