incandescent
adj
This word carries a dual energy of heat and brilliance. In a technical sense, it describes the physical process of glowing due to high temperature, creating a warm, yellowish light that feels organic and intense compared to the sterile flicker of LEDs. When applied to human emotion, it suggests a state of being so overwhelmed by feeling that the person seems to radiate energy. It is often used for extreme anger, where the person is metaphorically burning up, or for a state of pure, blinding joy that transcends ordinary happiness.
