So you need an ultra bright flashlight? You could always build your own 1000W LED flashlight. As rctestflight mentions on YouTube, he used 10 x 100-watt LED chips, each one attached to a large heat sink with bolts and thermal compound to help the heat transfer. This 1000W LED flashlight can help you see quite well at night.
