Fluorescent lamp starters are rated by wattage, and it's important you use the right starter for the tube in your fixture. If the problem is not in the tube, try changing the starter. To install a starter in afluorescent fixture, simplyinsert the starter and twist it to secure it in its socket. Likewise, repeated flickering or flashing will wear out the starter, causing the insulation at the starter to deteriorate. A dim tube usually requires replacement, and failure to replace it can strain other parts of the fixture. These are warning signals, and you should make the necessary repairs as soon as you notice any change in the lamp's normal performance. All fluorescent lamps grow dimmer with age, and they may even begin to flicker or flash on and off. In some kinds of fixtures, the starters are built in and cannot be individually replaced.Since there are only three primary parts in a fluorescent lamp, you can usually take care of any repairs yourself. Fixtures with four tubes, similarly, have four starters and four ballasts. The fixture may appear to have two tubes working off one ballast, but actually there are two ballasts built into one case. These lamps must have individual starters and ballasts for each tube. Many fluorescent fixtures have more than one tube in order to provide more light. The starter closes whenever you deenergize the fixture. Once it senses that the lamp is glowing, it stays open. In most fluorescent fixtures, the starter is an automatic switch. It makes a surge of current arc through the tube when the starter opens, and then it keeps the current flowing at the right rate once the tube is glowing. The ballast is a magnetic coil that adjusts the current through the tube.
