ABSTRACT:
A replacement fluorescent lighting device includes a fluorescent lamp having a plurality of parallel tubes elongated along an axis and a reflector with an annual reflecting inner surface surrounding the tubes. The inner surface includes at least one surface, or surface segment, that is defined by a geometric curve rotated at least partially about a given axis, with the curve having a focal point that is laterally offset from the given axis in order to have a focal ring segment to enhance light emitted by the surface of the fluorescent tubes. Multiple surface segments are defined about an axis offset from the lamp axis of elongation and spaced radially around the fluorescent lamp. These segments are positioned at major lumen output lobes of the lamp.
