of radiated power and lumens is not fixed at 683, but it varies according to the wavelength so that a light source with a luminous flux of 1,000 lumens will appear, to the human eye, to be delivering twice the amount of light as a similar source with a luminous flux of 500 lumens....
Lumens refer to the total amount of visible light a device produces. A higher lumens value means there is a larger area that is lit. Say the candle that we just saw above at 1 cd shines in all directions - 360 degrees. It would give off 12.57 lumens (lm). That’s the total light ...
Theluminous fluxis similar to a quantity of (light) energy, and if you spread it over a larger surface area, the light will become dimmer. For instance, if a luminous flux of 1000lumensis spread across 1 square meter, that’s 1000 LUX. If 1000 lumens is spread across 10 square meters...
