Ever looked at your room and thought, “This could use… more sun?”

Matt from DIY Perks did exactly that and built a 120,000-lumen LED “Supernova” light. Unfortunately, it turns out that when you crank brightness to that level, you also get heat. Lots of it. So he strapped on 18 fans and six chunky copper radiators to the “flashlight.”

The final result? A glowing sci-fi reactor core that could probably tan you from across the street. Sunglasses highly recommended.
