effulgence

Effulgence is a literary word for radiant brightness or brilliant light streaming outward from a source.

It suggests luminosity that seems to pour forth abundantly, like sunlight flooding through clouds or the glow emanating from a flame.

The word appears most often in poetry, religious writing, and elevated prose to describe divine light, celestial bodies, or metaphorical brilliance of spirit.

The effulgence of the setting sun transformed the ordinary landscape into something sublime.
