Gadget Freak Case #228: Super LED Flashlight Hits 3,000 Lumens

John Duffy, a 15-year-old Gadget Freak, has put together a powerful LED flashlight that runs at almost 30W and 3,000 lumens.

Fifteen-year-old Gadget Freak John Duffy has put together a powerful LED flashlight. He calls the LED a major advance over Edison's incandescent lighting. "Nowadays we have LEDs that are significantly more powerful and efficient, and they run on low-voltage DC."

Duffy's super LED flashlight runs at almost 30W and 3,000 lumens. By comparison, bright xenon car headlights reach about 1,000 lumens. He says you have to be careful building and using this gadget, because it is powerful enough to blind someone if used up close. He used welding glasses while constructing the flashlight.

John Duffy's super LED flashlight is almost three times as powerful as xenon car headlights.
