Candela (cd) is a unit of luminous intensity, measuring the amount of light emitted in a specific direction. Luminous flux (lumen, lm), on the other hand, quantifies the total amount of visible light emitted by a source, irrespective of direction. To convert from candela to luminous flux, you’d need additional information about the light source’s distribution, as they are fundamentally different concepts.

FAQs
How many lux is equal to 1 candela? 1 candela (cd) is approximately equal to 1 lumen per square meter (1 lux).
Can you convert candela to lumens? No, you cannot directly convert candela to lumens because they are different measurements. Candela measures luminous intensity, while lumens measure luminous flux. However, you can calculate luminous flux (lumens) by multiplying candela by the solid angle in steradians (lm = cd * sr).
What is the difference between candela and luminous flux? Candela (cd) measures luminous intensity, which is the brightness of a light source in a specific direction. Luminous flux (lumens) measures the total amount of visible light emitted by a source in all directions.
