And it last at least 3 days per one dip in water. I've bought other brand of emergency light before and it was not reusable plus the brightness was a lot less than the Mizu Light. I showed it to my 6 years old boy how to activate and operate it. He started to ask me why water gives it power. Amazing, isn't it! I will get more for my car, rooms, and my son's school survival kit. Because when you need it, activate with water and you have light. No need to worry about batteries getting old or no juice.
