WebIn the 1950s and 1960s, installing fluorescent lighting fixtures by the millions to boost light levels made sense, especially with energy prices low. And over the years, the efficiency of the tubes did improve -- from 40 lpw to about 70 lpw. As less efficient tubes burned out, they gave way to more efficient replacements. WebNov 29, 2024 · American inventor Thomas Edison, who made the first electric light bulb, was considered one of the first inventors to apply for a patent (U.S. Patent 865,367) of the earliest version of the fluorescent lamp on May 19, 1896, later published in September 10, 1907. He used x-rays to excite the phosphor; but unfortunately, his model was never sold. WebThe fluorescent tube, also referred to as the fluorescent strip or tube light, is a low-pressure mercury vapour gas-discharge tube that converts fluorescence into visible light. This process involves the triggering of mercury vapour via an electric charge, resulting in the appearance of a short-wave ultraviolet light. imrc congress 2022
