light less a part of the wavelength of visible light. to be able to
make up for the small number of bands. Speeches will be able to enhance
the color of sunlight --- Ra (CRI) value is 100 - covers a full
spectrum of visible light. is now less commonly used in 495 white LED ~
505 wavelengths. if done LED color rendering index is 80 to 90 in
everyday life have been able. now we have a large amount of fluorescent
