What 燡 means
It means intense fire or brilliant radiance. Classical glosses link fierce fire with bright light. 火 supplies the fire meaning; 睪 is a pronunciation cue.
《魯靈光殿賦》 is an Eastern Han literary work about the Lu Lingguang Palace and an early written citation of 燡.
Literary and archaic; it fits a classical quotation or a study of Chinese characters.
