The light is made from a 50 MM PVC tube, a waterproof plug holder (red thing), and a Halogen light.
The Halogen light is fitted with 8 LEDs instead of a bulb, its pretty expensive (30 Euro`s) but it only takes 1 watt of power
The batterys are 10 rechargeable Ni-MH 1.2 V AA`s in serial, placed in a holder.
The battery supplies 12 V / 2000 mAh, wich gives me a runtime of
24 hr in theory.
With two lights it takes only 2 W of power, wich gives me a good 12 hr runtime.
