What is the formula for lumens?

Obtain the candela and the vertex angle in degrees of the light source. (These values ​​are in catalogs and the internet). Enter the candela and degrees into the formula: lumens = candela × (2π (1 – cos (degrees / 2))) . Example: An LED luminaire produces 1.5 candela at a corner angle of 70 °, how many lumens does it produce?
