Unreasonably bright bike light apparently hunts deer
Friday, October 23, 2009
[Jukka] wanted a bike light that wasn’t afraid to go into the woods during the dark winter. He put together a lamp that uses eight 3 Watt LEDs to pump out 1680 lumens (english translation). The high power LEDs were mounted on a large aluminum heat sink and use lenses to optimize the beam of light. The system uses a 2 amp driver board that he assembled himself. Power is provided by sixteen AA Nickel Metal Hydride batteries that are housed along with the driver circuit in a water bottle.
This more than doubles the output of the last bike light we thought was too bright. Where will this lumen-arms-race stop?
[Thanks Sami]
