A fluorescent tube is a long, thin type of light that is attached to fittings on walls and ceilings. The tube works by exiting mercury atoms with electricity to produce visible light. If the light starts to flicker, or if only one end of the tube works, the starter will need to be replaced. If the light doesn’t turn on at all, you will need to replace the entire tube. The light’s instruction manual will advise you on the size and type of replacement fluorescent tube required.
4Fluorescent tubes contain small amounts of mercury, so dispose of them correctly through a recycling program.Always ensure the light switch and circuit is turned off before changing the fluorescent tube.Never apply pressure to the middle section of the bulb.
Remove the fluorescent tube's cover glass (if applicable), by gently pushing upward on the glass cover, then tilting it toward you. Some glass covers are held in place by screws at each end of the support bracket; unscrew them with a suitable-sized screwdriver.
Replace the starter if the light still isn't working; the starter is located in the fitting racket. Repeat steps 1 and 2. Press the starter inward, turn it so that it faces away from you, and then remove it. Insert the new starter, push it into place, and it turn toward you to lock.
