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 color that takes out the blue and leaves only the fluorescent colors.
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.

After several night dives as an AOW diver, I was excited to try a UV night dive. It did not disappoint! Pure Diving provided the specialized equipment (visor and blue light) and made sure everyone was comfortable with it and knew what to expect with this particular site.
We swam against a bit of current for about 25 minutes, then turned around and drifted back. It's amazing how different corals, fish and other sea creatures "light up" under ultraviolet light!
Even swimming back to shore was magical, with the stars and moon shining down. Pure Diving knows how to put on a great dive, and a UV night dive with them is really something you need to try.
