Water-Activated Emergency Light Shines for a Week Without Power

A water-activated emergency light can illuminate for 168 hours (one week) after being submerged in water, offering a reliable lighting solution during prolonged power outages caused by disasters like earthquakes. The product, called "AQUMO Candle," comes in two types: an orange-cap "disaster light" for direct illumination and a yellow-cap "blackout light" for diffused lighting. It works with any liquid, including rainwater, seawater, juice, coffee, or alcohol, and requires only a two-second immersion. The light's brightness is comparable to a single candle, sufficient for basic tasks like checking footing or eating in darkness. It has a shelf life of over ten years, eliminating concerns about battery leakage or discharge, making it a practical addition to emergency kits.
