How to Evaluate Light flux?

Light flux evaluator uses Flux = Photoelectric Current/Photoelectric Sensitivity to evaluate the Flux, The Light flux formula is defined as is energy per unit time that is radiated from a source over visible wavelengths. More specifically, it is energy radiated over wavelengths sensitive to the human eye, from about 330 nm to 780 nm. Thus, luminous flux is a weighted average of the Radiant Flux in the visible spectrum. Flux is denoted by Φ symbol.

How to evaluate Light flux using this online evaluator? To use this online evaluator for Light flux, enter Photoelectric Current (I_pc) & Photoelectric Sensitivity (P_s) and hit the calculate button.
