Light is electromagnetic radiation ranging in wavelength from about 400 to 700 nanometers and propagated at a speed of 186,282 miles per second.
John 8:12 Then Jesus again spoke to them, saying, “I am the Light of the world; he who follows Me will not walk in the darkness, but will have the Light of life.”
Visible
Blue is one of the highest intensity types of visible light with very short wavelengths that produce a high amount of energy. Blue is the most damaging to our eyes in the visible spectrum. This high-energy visible (HEV) corresponds to a wavelength range between 400 -500 nanometers (nm).

Go Glo !!
1 Thessalonians 5:5 For you are all sons of the light and sons of the day; we do not belong to the night or to the darkness.
