Dear Udara, The spectral power distribution can be determined by a typical fluorescence spectrometer, e.g. from Edinburgh Instruments or Ocean Optics. In order to determine absolute values you ...lm = 3cd*2*π* (1-cos (70°/2)) lm ≈ 3,39. So it is true, if we increase the apex angle of a lamp while keeping the luminous intensity the same, the lumen output will also increase. We can also test this the other way around, lets keep the apex angle at 70°, but reduce the light intensity a half, from 3cd to 1,5cd.Are you passionate about healthcare and looking to jumpstart your nursing career?
