How Do You Stop A Fluorescent Tube Flicker?
A fluorescent lamp is a glass tube coated with phosphor powder, and filled with an inert gas and a small amount of mercury. There are electrodes on each end which, when turned on, cause electrons to move through the gas from one end of the tube to the other. This transforms the liquid mercury into a gas, and as electrons collide with the gaseous mercury, ultraviolet light is released. This ultraviolet light is not visible to the human eye, but as it hits the coating on the tube, the phosphor atoms give off white light. A flickering in the tube can be caused by one of three things–a defective lamp, defective ballast or defective starter. Check the tubes. The tubes are the least expensive part of a fluorescent fixture, and the easiest to replace. Defective fluorescent tubes will flicker and cause other tubes paired with them to flicker. If allowed to continue flickering, these defective tubes will cause the ballast to overheat and fail prematurely. Tubes need to be replaced if the elect
