The blue light used in fluorescent night diving is not a blacklight. The blacklight would work, but due to the physical properties of water, the specific wavelength of our blue lights has better results.
In order to get the best results, something has to take the blue out of the light that bounces of what you’re looking at. Therefore, we wear a visor that covers our masks. This visor has a specific yellow colour that takes out the blue and leaves only the fluorescent colours.

For the absolute best results, we only use the best equipment available on the market. A lot of research has gone into the equipment we use to get the perfect wavelength of light for optimal excitation of the coral.
