Older preheat fluorescent fixtures, common in desk lamps, under cabinet lights, mirrors and some shop lights, need a small plug-in starter to light the tube. When the tube flickers or only the ends glow, the starter is often the problem. This category stocks Satco starters with condensers: FS-2 for 14W, 15W and 20W lamps, FS-5 for 4W, 6W and 8W lamps, and FS-25 for 25W lamps, in single, carded two-pack and 5-pack options plus a metal-case version. Match the starter to the tube's wattage, which is printed on the tube and the fixture label. If you are replacing many fixtures, consider an LED tube that needs no starter or ballast.
Starters are small devices used to initiate the operation of fluorescent lamps, particularly in preheat fixtures. They temporarily allow current to flow through the lamp�s filaments before switching off, enabling the lamp to strike an arc and begin glowing. Starters are commonly used in older fluorescent systems with magnetic ballasts.
Available in various voltage ratings, starters are easy to replace and are essential for consistent performance in legacy lighting systems.
