Yes I was referring to the "night sea" gear. I'm not an expert but I believe the natural florescence is caused by photo-proteins which are not present in all corals. The purpose of these proteins are to act as a natural sunscreen to reflect UV light. In order to see this natural florescence you need to filter out all the light except for the UV spectrum which is basically what the night sea flashlight and filter do. The idea is the light is created naturally like a kind of bio-luminance or something.
From what I remember reading the night sea flashlight was similar to other UV flashlights available elsewhere for less.
