You may have seen many high lumen flashlights, getting thousand lumens at turbo mode but only produce max output for a very short period. For example, one claims 10000 lumens at turbo mode, lasting for 10s and then stepping down to a lower output. So why set up like this?
As LEDs produce heat, a handheld flashlight could only dissipate a limited amount of heat. Especially on turbo modes, it generates a lot of heat, enough to damage the electronics and even burn the hands, so it's common for high output flashlights to step down before overheating. And it's also a way about battery conservation when you are using the flashlight outside.
Some people think a few seconds of the burst just doesn't seem very useful. While many users tell turbo mode is useful for quickly checking things in the distance, when the standard high mode may not provide enough light. Are you willing to buy a light that is super bright but only has a limited run time at turbo brightness? How do you usually use the turbo mode?
