ABSTRACT:
In a fluorescent lamp, a circuit board assembly is provided within the base of the lamp. The circuit board assembly includes a circuit board having a plurality of conductive runs thereon, a lamp starter circuit and device electrically coupling the pins of the lamp base to the circuit board. The conductive runs have a concave cut-out portion located immediately adjacent the location where an electrical coupling lead is coupled (e.g. by soldering) to the runs. The concave cut-out portion prevents the circuit runs from lifting off from the circuit board when the electrical coupling lead is bent after being coupled to the circuit runs.
