A foot-candle (sometimes foot candle; abbreviated fc, lm/ft 2, or sometimes ft-c) is a non-SI unit of illuminance or light intensity. The foot-candle is defined as one lumen per square foot. This unit is commonly used in lighting layouts in parts of the world where United States customary units are used, mainly the United States. [1]

In visual physiology, adaptation is the ability of the retina of the eye to adjust to various levels of light. Natural night vision, or scotopic vision, is the ability to see under low-light conditions. In humans, rod cells are exclusively responsible for night vision, as cone cells are only able to function at higher illumination levels. [1]
Daylight harvesting systems are typically designed to maintain a minimum recommended light level. [1] This light level will vary according to the needs and use of the space; for example, the commonly recommended light level for offices is 500 Lux (or around 50 foot-candles) on the desktop.
The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. [20] This limitation is typically ignored in photography, where f-number is often used regardless of the distance to the object. In optical design, an alternative is often needed for systems where the object is not far from the lens.
[1] Subsequently, the FIA awarded rights to a Formula Regional championship in Japan to K2, promoters of the F4 Japanese Championship, which will name their series the Formula Regional Japanese Championship. With the rebranding of the series to Super Formula Lights, the Japanese Formula 3 championship officially ended after 41 years. The Japan ...
The FIA Formula 3 European Championship was a European Formula Three (F3) auto racing competition, organised by the Fédération Internationale de l'Automobile (FIA). After one season of the FIA Formula 3 International Trophy, the FIA revived the FIA Formula 3 European Championship. [1]
It could cruise for relatively long periods at Mach 1.2 (1,470 km/h; 913 mph) and had a dash speed of Mach 1.5. Against a target flying at these speeds, the existing Gloster Javelin interceptors would be useless; its primary de Havilland Firestreak armament could only attack from the rear and the Tu-22 would run away from the Javelin in that ...
