Abstract：The luminous photometry based on the spectral response of human eyes does not adapt to the evaluation of plant lighting, however most commercial light sources or luminaires are marked as luminous photometry parameters, which lead to the lack of unified standard in plant lighting design .It has become an uncertainty for lighting engineers of what illuminance should be used when lighting concerns plants .This paper distinguishes four evaluation systems of plant lighting taking account of the different effects of light intensity, spectral power distribution and light period , and provides their cross transformational methods and coefficients among the four photometry .The measures and suggestions about promoting plant growth and preventing plant damage are also proposed .
