incandescent

At its most literal, "incandescent" describes something that glows with intense heat, like the filament inside an old-fashioned light bulb or white-hot metal. It paints a mental picture of light so bright and pure that it seems to be born directly from extreme energy. In a figurative sense, it describes someone who is radiating intense emotion, most commonly extreme anger or overwhelming passion. While it is a sophisticated word, it is often used in literature or journalism to describe a person’s spirit or a sudden flare-up of temper.
