The 20,000 lumen flashlight is commonly known as the search light torch, which is developed based on the concept of outdoor rescue. Different from other LED flashlights, it uses 21700 rechargeable lithium batteries with 20000 lumens and 32000 mAh capacity, which can not only provide high-brightness lighting for the dark night, but also provide 3 hours of battery life.
High-brightness flashlights are not suitable for all usage environments. In my opinion, the light intensity of 20,000 lumens is limited to remote mountainous areas and dark forests, where rescued people cannot be easily found. At this time, we need one or more high-lumen flashlights to rescue the victims. In addition, this flashlight can not only be used to save people, but also to save yourself. Thanks to the 32000mAh large-capacity battery design, it can become a large power bank, which can charge headlamps, communication equipment or rescue equipment. Secondly, the aluminum alloy casing does not have to worry about being damaged by branches. If it is a household flashlight, a 1400-lumen rechargeable flashlight is the best choice, both in terms of price and practicality, it is far more acceptable than a 20,000-lumen search and rescue flashlight.
In short, a 20,000-lumen flashlight is designed for outdoor search and rescue or other first aid, and a household flashlight below 1,400 lumens is a necessity in our daily life.
