Introducing the JL-MY-002 Prep Saltwater Lamp, the ultimate maintenance-free lighting solution for emergencies. Unlike traditional flashlights, this innovative lamp requires no charging and contains no built-in batteries, guaranteeing a safe, stable, and incredibly long shelf life. It operates simply by adding saltwater or seawater (3% to 20% salinity) and has no strict water quality requirements.  

Engineered for extreme environments, the JL-MY-002 performs flawlessly in temperatures ranging from -20°C to 55°C. It provides a bright 250-lumen cool white light and features two adjustable brightness levels. On the low setting (Gear 1), simply refresh the water every 10 to 12 hours; on the high setting (Gear 2), refresh it every 8 to 10 hours.  

Remarkably, this compact device (76x52x90mm) offers an impressive total illumination lifespan of around 400 hours. Designed with no replaceable parts, it is completely maintenance-free, making it the premier choice for disaster preparedness and survival kits. Lightweight at just 137g when packaged and requiring only 6-15g of salt per use, the JL-MY-002 ensures you are never left in the dark.
