[Disaster Prevention] Lights up even in muddy water or juice! A portable light that generates power with water, prepared for "10 years ahead"

In times of disaster or power outages, a reassuring item is the emergency light "DIP Light." It lights up simply by being immersed in water, so no power or fuel is needed. With up to 72 hours of continuous lighting and a long-term storage life of up to 10 years, it ensures a reliable illumination even in the darkest nights.

The "Dip Light" is an emergency light that emits light using only water, without relying on batteries or charging. It can create a light source using surrounding moisture, including tap water, rainwater, or melted snow.

The mechanism extracts electricity from the reaction between metal and oxygen in the air, and saltwater solution. Since it does not have a built-in battery, there is no worry about leakage or running out of charge even if stored for a long time.

Can be illuminated continuously for up to 72 hours after being soaked in water. Even during long power outages or nighttime evacuation situations, it will continue to light up your feet and hands. When the light begins to dim, you can restore brightness by rehydrating it. It’s reassuring that it’s not disposable and can be reused.

Because it doesn’t use batteries or any battery structure, it can be stored for up to 10 years. You’ll be free from the hassle of replacing batteries like with a flashlight every few years. Whether kept in your disaster preparedness backpack or tucked away in the back of a closet, it will be useful when the time comes.

Heavy and bulky disaster preparedness items tend to take up space in your emergency backpack. In this respect, the "Dip Light" at approximately 22g is ultra-light and compact. Not only is it suitable for disaster preparedness bags, but it can also be distributed to places that need lighting when it gets dark, such as next to the bed in the bedroom, in the entryway, in the bathroom, in the kitchen, and in the car’s glove compartment.

By covering it with a glass or placing a plastic bottle on top, it can quickly transform into a simple lantern that softly illuminates the surroundings. It’s useful in areas where the family gathers, like the living room or around the table during a power outage. With an on/off switch, it can be lit only when necessary.

Reduces environmental impact and can be disposed of with regular waste.

The electrolyte is saltwater and can be disposed of as general waste once used up. There’s no need to search for a dedicated recycling box or follow bulky waste procedures like batteries or accumulators.

Since there are no costs for purchasing batteries or the electricity to charge them, it helps keep running costs down while also preparing for disasters. As they are consumables that will eventually reach the end of their lifespan, ease of disposal and minimal environmental impact cannot be overlooked.
