Edmund Germer (August 24, 1901 - August 10, 1987) was a German inventor granted as the father of the fluorescent lamp for which he deposited U.S. Patent No 2,182,732 in 1926 with Friedrich Meyer and Hans J. Spanner. It was later purchased by the General Electric Company, which also licensed his patent on the high-pressure mercury-vapor lamp.

The idea of coating the tube of an arc lamp emitting in the ultraviolet with fluorescing powder to transform UV into visible light led to the realization of arc discharge emitters with spectral quality competing with incandescent emitters. Prior to that, the unpleasant color of the emitted light made these lamps unfit for daily use, despite their much higher efficiency. The 300,000-watt Plasma Arc Lamp in the Infrared Processing Center (IPC) at Oak Ridge National Laboratory An arc lamp is a device that produces light by the sparking (or arcing, from voltaic arc or electric arc) of a high current between two carbon rod electrodes. ... Ultraviolet (UV) radiation is electromagnetic radiation of a wavelength shorter than that of the visible region, but longer than that of soft X-rays. ... Fluorescence induced by exposure to ultraviolet light in vials containing various sized cadmium selenide (CdSe) quantum dots. ... The 300,000-watt Plasma Arc Lamp in the Infrared Processing Center (IPC) at Oak Ridge National Laboratory An arc lamp is a device that produces light by the sparking (or arcing, from voltaic arc or electric arc) of a high current between two carbon rod electrodes. ... The incandescent light bulb (archaically known as the electric lamp) uses a glowing wire filament heated to white-hot by electrical resistance, to generate light (a process known as thermal radiation or incandescence). ...
