Aqua Lamp is powered by a magnesium fuel cell and includes a pre-installed magnesium power bar that when immersed in salt water, creates electricity. It uses regular table salt and tap water, or seawater.
The power bar will dissolve after approximately 100 hours, thus stopping power generation, at this time simply replace the power bar and add more salt and water. The magnesium power bar and residual salt water are safe, non-toxic and Earth-friendly. Magnesium power bars can be stored for up to 25 years, the lamps Cree LEDs can last up to 50,000 hours. Great for camping, boating, remote work sites and off the grid locations
