YouTube user rctestflight in a video released on Saturday, the show he had just made the “world’s brightest flashlight”, allegedly capable of night into day.
Rctestflight homemade “flashlight” is not like a regular flashlight, he uses 10 100 watt LED chips connected together, each chip equipped with a large aluminum heat sink, and the use of batteries. The “flashlight” weighs 4.5kg, the sustainable use of 10 minutes after connecting the battery.
However rctestflight said under this 1000watt / 90000lumen of LED flashlight in most cases is not very useful, because if used within 30 meters, then will seriously affect vision.
