Most fluorescent tubes flicker or swirl for up to 100 hours when brand-new. I have a finicky light in my closet. Once successfully lit, the fluorescent lamp remains on, operating at a lower voltage, giving off light as the ionized gas excites the phosphorescent coating on the inside of the lamp tube. The flow of electrons between the lamp filaments excites the electrons in atoms of mercury inside the tube, causing them to emit radiant energy in the form of UV (ultraviolet) light. Precaution: Identify the light fixture circuit, turn it OFF and Tag it with a Note before working with the wiring.
