Hey ,
This is something I started a while back but never finished , turned out pretty well ( I think xD ) as I have no access to lathes or mills it was made from sheet steel and tin snips and a drill .
Battery is a 6 cell 350mA/h Lithium ion polymer I made myself for individual cells and the driver is a RCD-0.7 ( 700ma ) .
The Led is from led engine and is rated for 11W input power with a Vf of 16.4 Volts and a operating current of 700mA , the rated light output is around 1.2 Watts .
The led is mounted to a head sink with a 40mm fan on the back and this seems to be just the right size for this led . The fan gets its 12 volts from the lithium cell and draws 100mA so i'm losing 1.2W in the regulator .
Pictures !
