A fluorescent lamp protection device, which comprises a solid state timer for controlling the state of a delay-and normal-closed contact so as to control a starter of a fluorescent lamp; the delay-and-normal-closed contact is connected in series with an auxiliary starting capacitor, and then both of them are connected in parallel with an original starting capacitor. The operation power supply of the solid state timer is a D.C. power supply provided by the instant starter of the fluorescent lamp. When the lamp is being turned on, the auxiliary starting capacitor is used for reducing the instantaneous pulse voltage applied to both ends of the fluorescent lamp so as to protect the lamp and to increase the serviceable life thereof.
