- n. A unit of luminous intensity equal to 1/60 of the luminous intensity per square centimeter of a blackbody radiating at the temperature of solidification of platinum (2,046°K). Also called candle. See Table at measurement.
- n. In the International System of Units, the base unit of luminous intensity; the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian. Symbol: cd

“Unit of luminous intensity candela The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.”
“More formally, a candela is the intensity of a source that puts out yellow light at 1/683 watt per steradian of solid angle.”
“Unfortunately, it wasn't - and after much searching the title of the track is 'candela' by Da Madd Dominikans (in case anyone else needs to find it).”
“This redefinition would bring the kilogram into line with the six other base units that make up the International System of Units SI – the metre, the second, the ampere, the kelvin, the mole and the candela.”
“I worked on the candela, a not-too-fancy move that I've nevertheless had persistent trouble with, and seem to have it down:”
“Following an international inquiry by the BIPM, which began in 1948, the 10th CGPM, in 1954, approved the introduction of the ampere, the kelvin and the candela as base units, respectively, for electric current, thermodynamic temperature and luminous intensity.”
“:Ecodesign: come riscaldarsi con una candela in ufficio durante queste grigie e umide giornate d'inverno::.”
“Flashbangs produced an incredibly bright light—approximately two million candela, which even with eyes closed would cause a bleaching of the rhodopsin, the visual purple in the eye, creating the spots and temporary blindness most people have experienced and referred to as the flashbulb effect.”
“Light intensity from the light distribution curve in candela (cd)”
“The term light adaptation is used if the luminance is at least a few candela per square metre; if it is less than some hundredth parts of a candela per square metre one speaks of dark adaptation.”
These user-created lists contain the word ‘candela’.
These come from gamma meditation ,I think.
Candles, candle-making; photometry, and a couple of oily fish used as light sources.
Words that are becoming more important as we learn more about alternative and renewable energy sources.
