ABSTRACT:
A circular fluorescent lamp unit having a central screw-in hub containing lamp ballast means, and a plurality of support arms extending from the hub and having curved outer ends to support a circular lamp. The support arms are metal or plastic strips which enter through slots of the hub and are bent at substantially right angles within the hub so as to be held in place while having limited radial movement with respect to the hub to enable them to accommodate and support circular lamp bulbs of varying dimensions such as due to manufacturing tolerance variations.
