Sea Dragon dive lights can be used as a primary source of light or as a back-up light. SeaLife offers several underwater lighting choices ranging from a narrow concentrated dive light beam to a wide-beam photo/video light, or a dual beam that offers both wide and narrow beam settings. As a primary light, Sea Dragon lights offer exceptional brightness and a generous amount of run time.  There are a number of ways you can hold or carry your Sea Dragon Dive light, check out the options available for each light.
