In the 1970s, Thorn Lighting introduced an energy-saving 8 ft retrofit tube in Europe. Designed to run on the existing 125 W (240 V) series ballast but with a different gas fill and operating voltage, the tube operated at only 100 W. Increased efficiency meant that the tube produced only 9% lumen reduction for a 20% power reduction. [ 7 ]
The extended lifespan and improved efficacy of incandescent bulbs negated one of the key advantages of Moore's lamp, but GE purchased the relevant patents in 1912. These patents and the inventive efforts that supported them were of considerable value when the firm took up fluorescent lighting more than two decades later.

The most commonly used A-series light bulb type is an A60 bulb [7] (or its inch-based equivalent, the A19 bulb [2] [4]), which is 60 mm (19 ⁄ 8 in or 2 + 3 ⁄ 8 in) wide at its widest point [3] and approximately 110 mm (4 + 3 ⁄ 8 in) in length. [8] Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80.
Mazda brand bulbs at the Edison and Ford Winter Estates Edison Mazda light bulb tester, logo by Maxfield Parrish, at the Corning Museum of Glass. Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs.
Compared to a theoretical 100%-efficient lamp (680 lm/W), CFL lamps have lighting efficiency ranges of 7–10%, [39] versus 1.5–2.5% [40] for incandescents. [41] Because of their higher efficacy, CFLs use between one-seventh and one-third of the power of equivalent incandescent lamps. [38]
Color temperature has applications in lighting, [3] photography, [4] videography, [5] publishing, [6] manufacturing, [7] astrophysics, [8] and other fields. In practice, color temperature is most meaningful for light sources that correspond somewhat closely to the color of some black body, i.e., light in a range going from red to orange to ...
The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...
