The NightSea Head provides a unique experience in the dark. The blue light causes certain proteins and minerals to fluoresce with an unearthly glow, revealing a hidden world of plants, animals, and minerals all around. For best results, view through a yellow filter to see nothing but fluorescence!

The Gobe interchangeable heads are a wonderful idea to keep you from needing to buy (and haul) a whole separate light for each specific function. This Nightsea head comes with the flip-down cap that converts the blue light to white light, even though its not shown in the picture (I was worried that it wouldn't be included, but pleased to see that the head came complete).

The blue light is BRIGHT, and if you've used black lights in the past, you'll quickly note that with the naked eye you don't see any fluorescent reactions... only just blue light. Using a yellow filter (any regular yellow camera filter, or yellow acrylic sheet, doesn't need to be special branded), the effect is indistinguishable from what you remember from having a black light - with the added benefit of not damaging your eyes with UV radiation.

The white light from the flip down doesn't seem as bright as the wide 850 video light on its lowest setting - 120 Lumens.

Worked perfectly together with a yellow filter on my camera for visualizing fluorescence in some species of corals. I used it while snorkeling in the ocean at a depth of 10 feet.

When used at night with fluorescing critters it's absolutely awesome! You need the yellow filters for camera/video.

don't think its worth the money was not spectacular. expected more. not for a primary light

work great, but keep in mind that the angle is quite narrow (spot 20 degree).
