incandescence
Light from heat
Incandescence is the emission of light from something heated to high temperature—the glow of a hot iron bar, the filament in an old light bulb.
The word extends to any intense brightness or brilliance: the incandescence of the summer sun.
Figuratively, it describes passionate intensity or radiant energy: She performed with an incandescence that captivated the audience.
