I love HydraLight! I couldn’t wait to try it out, so I immediately opened it, and started figuring out what to do. It was easy. You unwrap the power source, and dip it in water for 7 – 10 seconds (that was easy!), then you take and vigorously shake the power source (to get the excess water off of it), and insert back into the Flashlight/Lantern. Next step is easy, you Power On. This Lantern will make so many things, in life, easier. I showed the HydraLight to Joe, my husband, and he was amazed at how bright this light truly is. He said “this flashlight, and Lantern, will be a lifesaver in the future.” I agreed. If we get a flat tire, at night, this Lantern will make it easy for him to change the tire. Especially, if it’s when he is on his way to work at 5:30 in the morning! He’ll be able to set the Lantern down, and work hands free, in the dark.
