Full Description JIS C 8152-2:2019 specifies the methods for obtaining the total luminous flux and the quantities concerning the light source colour of white light emitting diode (LED) modules and LED light engines for general lighting (hereafter referred to as the light source under test), using an integrating sphere. This method is applicable to the photometry of double-capped linear LED lamp and LED luminaire.
