    This version is still developing. The idea is to create a dimmable "Flood Light" for wild camping.

    The idea is to use 20 super bright white LEDs to make a light source as bright as a 20W bulb. This is much more then enough in camp site and consume only 2.5W at full load.

    A prototype with dimmable feature have been tested. PCB design will be finished short after the selection of suitable case.

Test setup at my workbench at home. Figure also show a scope, a car battery charger and two power supply.
   
Left shown the version 2a and right shown the version1.

This photo is taken by my Digital Camera Cannon PowertShoot A20 with about 1 second exposure time. The camera is similar to using film of ISO100.

For the version 2a.... Mum ask me what hell is that strong bright light.
