Abstract
A fluorescent lamp construction is described utilizing a particular combination of two different phosphor materials in order to produce more efficient emission of white color light and whose color temperature can be controlled. The particular phosphor combination can be utilized as a blended mixture; and the color point of the lamp emission can be adjusted to approximate black body radiation emission such as incandescent lamp emission with negligible loss in optimum luminous efficacy.
