    Spectral Luminous Efficiency
    lang:""
    \(V(\lambda) = \frac{\Phi_\lambda(\lambda_m)}{\Phi_\lambda(\lambda)}\), where \(\Phi_\lambda(\lambda_m)\) is the spectral radiant flux at wavelength \(\lambda_m\) and \(\Phi_\lambda(\lambda)\) is the spectral radiant flux at wavelength \(\lambda\), such that both radiations produce equal luminous sensations under specified photometric conditions and \(\lambda_m\) is chosen so that the maximum value of this ratio is equal to 1.

    The Spectral Luminous Efficiency is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power. A common choice is to choose units such that the maximum possible efficacy, 683 lm/W, corresponds to an efficiency of 100%.
