Product Advantages Eco-friendly and energy-saving: No need to consume batteries or electricity, relies on salt water to generate power, no waste battery pollution Easy to operate: No complicated installation, just add water and salt to start, easy to use Stable lighting: Soft light without glare, moderate brightness, meeting emergency lighting needs Durable and sturdy: Waterproof and drop-resistant shell (some models), adapting to complex outdoor environments High cost-performance: One-time purchase, reusable, long-term usage cost is much lower than ordinary emergency lights Usage Instructions 1. Open the water inlet on the top/bottom of the lamp body, pour in clean water (tap water or mineral water) to the water level mark. 2. Add an appropriate amount of table salt (ordinary edible salt is acceptable), stir well until the salt is completely dissolved. 3. Tighten the water inlet cover, press the lamp switch to start lighting. 4. When the light dims, it means the electrolyte concentration in the salt water is insufficient; add a small amount of salt or replenish clean water, stir well and continue to use. 5. When not in use for a long time, pour out the internal salt water, rinse the inside of the lamp body with clean water, dry it and store it in a dry and ventilated place. Precautions Only clean water and ordinary table salt can be used; do not use seawater, soy sauce, vinegar or other liquids or chemicals to avoid damaging the lamp body. Do not add water exceeding the water level mark to avoid salt water overflow, which may corrode the lamp body or cause a short circuit. Do not disassemble the internal structure of the lamp body to avoid damaging the power generation components and affecting the use effect. Avoid placing the lamp body in high temperature, exposure to sunlight or humid environments to prevent shell aging or internal short circuit. Children should use it under adult supervision to avoid eating salt water or disassembling the lamp body. If salt water accidentally touches the skin or eyes, rinse immediately with plenty of clean water and seek medical attention if necessary.
