A fluorescent fixture has three main parts: the bulb, ballast, and starter. In most fluorescent fixtures, the starter is an automatic switch. Once it senses that the lamp is glowing, it stays open. The starter closes whenever you deenergize the fixture. Many fluorescent fixtures have more than one tube in order to provide more light. These lamps must have individual starters and ballasts for each tube. The fixture may appear to have two tubes working off one ballast, but actually there are two ballasts built into one case. Fixtures with four tubes, similarly, have four starters and four ballasts. In some kinds of fixtures, the starters are built in and cannot be individually replaced.
