ABSTRACT:
A rapid start fluorescent lamp having an external conductive strip has a resistive element in the lamp base electrically connected to the conductive strip and a pin of the lamp base. The resistive element is made from a material which has a volume resistivity of about 10.sup.5 to about 10.sup.8 ohm-cm and a deflection temperature greater than 250.degree. C. at 1,820 kilo dynes/cm.sup.2. The resistive element is mounted in the lamp base metal housing and supports the metal pins or the resistive element is made into a washer shaped element and attached to one of the pins on the inside of the lamp base.
