These starters are designed to replace the original starter in magnetic ballast driven fluorescent strip lights and deluxe full hood manufactured by All-Glass Aquarium Co. or other major brands.
Starters should be replaced if light bulbs are not fully lit or if light starts to flicker. When replacing bulbs make sure to match the starter with the recommended lamps. The FS-22 is for use with 14 watt-15" tubes, 15 watt-18" tubes and 20 watt-24" tubes.
