The so-called full spectrum does not actually mean that it is exactly the same as sunlight, but it is close to sunlight in the visible light band, especially the blue light band and red light band at both ends.
1) Ordinary LEDs are very prominent in the blue light band. This is related to the excitation principle of LEDs. Most LEDs are excited by blue light, so the energy of blue light in the spectrum will be very high.
2) As for full-spectrum LEDs, most of them are excited by purple light. This kind of spectrum is more continuous, and the blue light band is not obviously prominent.
3) Although some full-spectrum LEDs still use blue-light-excited LEDs, they have been processed to reduce blue light. You can see that the peak value of blue light is significantly lower than that of ordinary LEDs. Although it is not as exciting as purple light, the spectrum is also continuous enough.
