Fluorescent Starters

Starters are common name for “glow tube starter”, these are the small cylindrical aluminum or plastic vessels that are used in fluorescent lighting systems. Inside the plastic or aluminum vessel is a small glass tube that is filled with a gas usually neon and a radio frequency interference suppression capacitor. At the base of the vessel are two twist and lock pins. Starters must be matched to the appropriate wattage of lamp that they are starting for reliable light and operation. Inside the glow tube there is a switch, this switch is normally open and when power is turned on the glow discharge tube heats the bimetal contact. After it is heated the bimetal contact is closed and provide the current needed to the fluorescent lamp that is in-line.
