Daniel Riley from Stratus Productions has built an homemade super bright LED flashlight bar that uses ten 100W LED chips to produce an estimated 90,000 Lumens of light.
The flashlight is powered by two 8 amp-hour lithium-polymer batteries (about 9 iPhones 6S batteries put together), and can run for about 10 minutes. Check out how does the 1,000W LED looks in video below.
