Do you need to see fluorescent dyes underwater? Commercial diving companies have successfully used NightSea lights for checking the integrity of pipelines. In this application the pipe is filled with water in which a fluorescent dye has been dissolved. Divers then swim the length of the pipe checking the joints for leaks. NightSea's blue lights are as good or better than ultraviolet for making the dye fluoresce, and are much smaller and less expensive than the available ultraviolet lights. All of the commercial dive customers who have tried the lights have been happy with the results. (One company has already bought 8 lights!)

The BlueStar Dive Package, pictured here, will put you in business quickly. The BlueStar flashlight lights up the fluorescence. The BlueBlock Filter Visor blocks the reflected blue light so that you can see the fluorescence with the best sensitivity. The Mask Strap Wrapper keeps the Filter Visor from getting lost on the job.
