FS-U 220-240 volt flourescent glow starter with condensor for tubes up to 65W or 5′ (1500mm). The starter should always be changed when the tube is replaced as a defective starter can drastically reduce the life of a new tube. Failure of a flourescent tube to light up is often due to a faulty starter rather than a faulty or burnt out tube. The starter is quick and easy to replace.
