The total luminous flux (lumen) of solid state lighting product shall be measured with an integrating sphere. Data from the integrating sphere will give the table of wavelength, spectrum and AD value. This result table and V(λ) table can use to find the total luminous flux (lumen) which the test shows the luminous will be similar with the table Because before measurement and taken, the light source under test shall be operated long enough to reach stabilization and temperature equilibrium. Graph of flux and graph of power can see flux does spectify uncertainty depend on the electrical power. The wavelength set at 380 - 800 nm which are close to the human eyes sense. The human eyes will see the color at 380-760 nm.
