Fluorescent light bulbs invented
WebNov 11, 2024 · It was two earlier inventors, Henry Woodward, and Matthew Evans, who invented the incandescent light bulb, whose patent was purchased by Thomas Edison. By 1879, Edison had switched to a carbon filament and the oxygen-less enclosure, and had produced a bulb that lasted initially for over fourteen hours. WebFluorescent lighting was invented by Peter Cooper Hewitt in 1901, when he was awarded a patent for his low-pressure mercury vapor lamp. This laid the foundation for the next generation of fluorescent light – a high-pressure mercury vapor lamp invented by Edmund Germer, Friedrich Meyer and Hans Spanner in 1927.
