The Moore lamp was the first commercially viable light-source based on gas discharges instead of incandescence; it was the predecessor to contemporary neon lighting and fluorescent lighting. [1] In his later career Moore developed a miniature neon lamp that was extensively used in electronic displays, as well as vacuum tubes that were used in ...
1994 T5 lamps with cool tip are introduced to become the leading fluorescent lamps with up to 117 lm/W with good color rendering. These and almost all new fluorescent lamps are to be operated on electronic ballasts only. [4] 1994 The first commercial sulfur lamp is sold by Fusion Lighting.
King described the construction and use of a lamp in September 1845, and British patent No. 10,919 was granted to him on November 4, 1845 [third-party source needed].
