Q: How does this \u201csaltwater light\u201d glow? What is required to activate it? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A: This saltwater lamp works by causing a chemical reaction between the metal inside (e.g., aluminum plate), carbon sheet, and salt water acting as an electrolyte to generate electricity to light the LEDs. To activate, simply mix one of the bags of salt provided with the product with approximately 200 ml of clean water to make salt water, which is then injected into the main unit. No prior charging is required.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Q: Once activated, how long does the light stay on? How bright is the light? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A: Once properly activated, the lamp will continuously illuminate for more than 120 hours (approximately 5 days or more). The brightness is 30 lumens (lm) and the power consumption is 0.2W. It is bright enough to illuminate the inside of a tent or part of a room, and is suitable for reading, simple tasks, and checking the surroundings.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
 A: The always-on mode is suitable when continuous illumination is required (e.g., for indoor lighting at night, work lights, etc.). The flashing mode is effective for emergency signals, alerts, and when you want to increase visibility from a distance (e.g., outdoor position indication, rescue signals, etc.). The mode can be easily switched by a switch.<\/pre>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: The product can be stored for a very long time (e.g., more than 10 years*) if it is unopened and unactivated. When storing, keep the product package intact in a cool, dry place out of direct sunlight, avoiding high temperatures and humidity. The salt bag provided should also be kept sealed.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

 Q: Is this saltwater lamp safe to use, especially indoors? Is it an environmentally friendly product? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: Yes, it is very safe. There is no risk of fire as with candles, and no harmful gases are emitted, so they can be used safely indoors. In addition, the materials used are selected for their low environmental impact and do not contain toxic heavy metals such as those found in common dry cell batteries.<\/pre>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

 Q: What are the dimensions and weight of the product? What are the advantages of the low-profile design? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: The dimensions are very thin, approximately 180 mm \u00d7 120 mm \u00d7 10 mm. The main unit weighs approximately 0.1 kg (when dry), and the total weight after salt water injection is approximately 0.3 kg, making it lightweight. This thin and lightweight design allows the product to be easily stored in a small space, such as in a disaster prevention bag or in the space between bookshelves, making it very convenient to carry around. It can also be hung on a wall or stood on a stand for greater flexibility in installation.<\/pre>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

 Q: Can I use any salt or water? Do I always need the salt bag that comes with it? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: We recommend that the salt bag provided be mixed with fresh water, as it has been adjusted to perform at optimal salt concentration. In an emergency, table salt and possibly seawater may be used, but performance (lighting duration and brightness) may vary. Please use the supplied salt whenever possible.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: The saltwater lamp is designed to continuously light up for more than 120 hours with a single injection of saltwater, and power generation ends when the internal metal electrodes are depleted. Basically, the lamp is used up after this continuous use cycle. When power generation is finished, drain the salt water inside and dispose of it properly according to the instructions of the local government. (*If the model can be reused by replacing the electrodes, etc., this should be noted. We are assuming here a typical use-up type.)<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t
A: Yes, the product is usually equipped with a switch to turn the power on\/off and to switch the lighting mode (always on\/blinking). Therefore, the light can be turned off and back on again as needed after startup.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
