    And you can see sooo much of the infrared and ultraviolet part of the spectrum. What you see is still a kind of pinkish-violet.

    By the way, no LED based light is “full spectrum”. That is a common lie. Growth lights have violet-blue LEDs in the 200-400nm range, and red ones in the 600-800nm range.

    If you do a spectrum analysis of any LED light, you will see distinctive, narrow peaks around the LEDs core frequencies, usually with a bandwidth of 12-40nm.
