Glowing with heat or light; shining brightly; in a state of incandescence.
From Latin ex- (out) + candescens (glowing, from candescere). Forms the base for excandescence and excandescency.
While 'incandescent' became the common word, 'excandescent' captures something stronger—it's the difference between 'glowing' (incandescent) and 'radiating brilliantly' (excandescent).
