The performance of any solar light will greatly depend on the weather condition in the area. All solar-powered devices perform poorly in cloudy conditions. If your solar panel can't access direct sunlight, it may take up to one day to fully charge the inbuilt battery. Additionally, several camping lamps feature high IP_XY protection ratings. This rating is an international standard that shows the level of protection a product has against environmental elements like dust and water. X will tell you the lamp's level of protection against dust while Y will tell you its level of protection against water. Since they are used in campsites, several camping lights perform well in wet conditions. However, some models are completely protected from water damage. These models can be immersed in water for a half-hour without issue and good examples are models with IP67 or IP68 ratings. Such lamps will be the perfect choice for you if you need a camping lantern that you can use on your fishing trips.
