Long-range flashlights are very useful for inspecting equipment in dirty workshops, where soot and soot cover the equipment and absorb light, and you need to follow the path of a cable or inspect something at a height of 30-40 meters while on the ground. Also, in wet weather, additional power helps to see something on the wet ground. Once I had a flashlight with a stated 600 thousand lux, my friend and I were looking for his fallen keys on the lawn, the grass had not yet grown, that is, the ground was black and it had rained. Even this amount of light was absorbed by the earth very easily. The new LEPs are great. A friend gave me a Acebeam Terminator, a very nice little flashlight. Focusing on LEP was helpful
