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.

Cameras with focal-plane shutters—even if they had PC connectors with X, F, M, or S-sync delays ("xenon sync" with zero delay and flashbulbs with peak delays of 5, 20, and 30 ms)—could not be used at speeds that attenuated guide numbers with most types of flashbulbs because their light curves were characterized by rapid rise and fall rates; the second shutter curtain would begin wiping ...
An incandescent light bulb has a CRI of 100. [1] High-CRI LED lighting is a light-emitting diode (LED) lighting source that offers a high color rendering index (CRI). CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.
Because of their higher efficacy, CFLs use between one-seventh and one-third of the power of equivalent incandescent lamps. [38] Of 2010 world total lighting sales, 50 to 70 percent were incandescent. [42] Replacing all inefficient lighting with CFLs would save 409 terawatt-hours (1.47 exajoules) per year, 2.5% of
