A self-contained fluorescent lamp unit, such as the "Bright Stik" type, has a pair of plastic end caps positioned at the ends of the light bulb. A plastic resistor ballast housing strip extends along the bulb and into slots in the end caps. Tabs extend from the end caps and alongside the plastic housing strip. These tabs are ultrasonically welded to the housing strip, thus holding the unit together.
