WebFeb 13, 2014 · Focus that light in a narrower cone and it becomes more intense. In a 32° cone it’ll be four times as bright (50cd) and if concentrated into only 6.5° each lumen makes 100 candela (i.e. 1,260cd from our standard candle). Approximately, for small angles: candela = lumens × 4200/ (cone-angle squared). Prior to 1948, various standards for luminous intensity were in use in a number of countries. These were typically based on the brightness of the flame from a "standard candle" of defined composition, or the brightness of an incandescent filament of specific design. One of the best-known of these was the English standard of candlepower. One candlepower was the light produced by a pure spermaceti candle weighing one sixth of a pound and burning at a rate of 120
