The latest DIY Perks video dropped yesterday: he built a 120'000 lumen light using a single massive LED that draws 1.5 kW! The LED alone costs $1'300, the whole setup weighs around 25 kg and requires water cooling to keep it from melting itself.

Not exactly something you'd throw in your pocket, but the engineering is impressive. At what point does "flashlight" stop being a flashlight and just become a portable sun?
