One Tip to tell the real performance of high-power lights
Nowadays, a flashlight with thousands of lumens is quite common, but due to overheating issues, most can only stay in turbo mode for a few seconds. Even if it steps down to a lower level, it won't last long. A few high-quality flashlights, on the other hand, can stay in turbo mode for a few minutes at a few thousand lumens and then light up steadily for hours after stepping down to a lower, but still high lumen output. Do you understand why there is such a significant difference?
