As a high-power LED flashlight, the 20,000 lumen flashlight has always attracted our attention. More and more people are discussing the lumen value and application of the brightest flashlight in the world. Some people think that 100,000 lumen flashlights are the future, as natural fires caused by global warming need to be used to light the road. Some people think that the powerful lumens of the CREE lamp beads used in LED flashlights will affect the heat dissipation of the flashlight. Once in low temperature weather, the temperature difference between inside and outside will cause the lens to fog up, which will affect the lighting effect. The rest believe that the design purpose of high-power flashlights is to solve outdoor search and rescue, flood control or power outage emergency, and the fundamental purpose is to give full play to the greatest advantages of high-brightness flashlights in emergencies. In fact, I quite agree with the last point of view. The purpose of high-power flashlight design is to provide higher brightness in uninhabited or dark situations, and ultimately achieve the purpose of rescue or flood fighting.
In my opinion, the lumen value of a high-power flashlight is usually around 20,000 lumens. The appropriate brightness not only meets the needs of night lighting, but also greatly helps battery life and heat dissipation. As we all know, as the light intensity increases, the power consumption will increase, and the heat dissipation will also increase accordingly. In order to solve the battery life problem of high-power flashlights, most manufacturers usually increase the battery capacity and prolong the charging time (although the built-in fast charging protocol will increase the loss of the battery), for long-term outdoor rescue, flood rescue and camping lighting Neither is the best solution. Therefore, I think the light intensity of 20,000 lumens is sufficient for most outdoor use environments.
