Convert cd to lumens
WebThe luminous intensity Iv in candela (cd) is equal to the luminous flux Φ v in lumens (lm), divided by 2 times pi times 1 minus cosine of half the apex angle θ in degrees (º): Iv (cd) … WebLuminous Intensity is the Flux per unit solid angle from a point light source. (unit: cd, candela) It is expressed in lumens per steradian cd=lm/sr. (Refer to Figure.6). For a point light source, the amount of light that passes in the cone is the same if the cone size changes according to a constant solid angle.
