With the shortest wavelength of 370nm chip and the longest wavelength of 800nm phosphor, this full spectrum achieves the coverage from 350nm to 1000nm, which is also the limitation of the test range for general spectrometers. Besides the two peaks of the chip, the spectrum at different wavelengths is distributed evenly with typical 20% relative intensities. The spectral power distribution can be observed more clearly with the logarithmic axis.
