In the beginning of the UV trend, the only lights available fell in the wavelength of about 455 (nm). This light did the job of causing the corals to fluoresce, but it could also create so much visible blue light that it sometimes diminished the impact of the glowing colors. To combat this, divers learned to use a yellow filter which cut back the excess blue, while still allowing the fluorescent colors to shine through.

Recently, advances in technology have made possible a new version of the UV LED which has a wavelength just outside the spectrum of visible light at about 395 (nm).  This LED still causes marine life to put on their fluorescent show, but since it is nearly invisible to the naked eye, only the glowing colours are revealed.  With no need for yellow filters.
