Unimpressed with the flashlights sold at your local outdoors store? Need to be able to spot bears at night from five miles away on your next camping trip? Just do what YouTube hacker Samm Sheperd did and build your own using eight 100-watt LED chips that produce somewhere around 72,000 lumens.

For comparison, the digital cinema projectors used in modern movie theaters only produce around 35,000 lumens of light. And if you’re wondering if a handheld flashlight this bright gets hot, the answer is an emphatic yes, which is why Sheperd actually had to incorporate a water-cooling system into its design to prevent it from melting down while in use.
