After calculation the result size will be displayed. 618.65877751 (cd) This calculator uses a particular formula in performing the calculations. First select your desired calculation type and then enter the lumen or candela value and the beam angle of your lamp. The calculator helps you to easily convert between candela and lumens as well as lumens and candela. So the lamp with the smaller beam angle has the higher candela value. In case of two lamps with the same lumen value and different beam angles, the luminous flux is distributed over a different solid angle. The luminous intensity results from the luminous flux related to the solid angle. But a comparison of these values seems to be difficult, because the luminous intensity additionally is direction-dependent.
times the square distance from the light source d 2 in square feet (ft 2). The luminous intensity I v in candela (cd) is equal to 0.09290304 times the illuminance E v in lux (lx). Candela Lumen Comparisonīoth values are transmission units. Candela to lux calculator Lux to candela calculation Lux to candela calculation with distance in feet. Especially for highly directional LED bulbs such as spots or LED recessed spotlights, the luminous intensity is sometimes indicated on the packaging or in the data sheet in addition to the luminous flux.
Just enter the candela value and the apex angle in degrees to get the corresponding lumens value. This is the luminous flux emitted in a specific direction in lumens. This is an online calculator to convert candela to lumens. Lumen is defined as the amount of light streaming outward through one steradian from a uniform point source with an. The luminous intensity of a light source is specified in candela.
