Is it possible for light to be low and glary at the same time?

Well, yes. This is a writing language technique. It is called an oxymoron. This is where two opposites are put together. For example: the cold sun, pretty ugly, failed success etc. I'm not sure why people use it, probably for dramatic or confusing effect, but oxymoron it is^_^ If you want more information, go on the link below or just google it^_^ Hope this helps much.
