(1)
- get one of these:

50 eur
- attach it somehow to a head band of an old head lamp.
- get a new 12V 4000...5000 mah nimh battery + 40eur (or for use two old 6V batteries, no need to buy a new charger +0eur)
- some wires and stuff, maybe some lenses ~10 eur
... so one might get 45 W halogen eqvivalent head lamp for 50...100 euros.
(2) More waterproof and less do-it-yourself lamp:

about same amount of light the one above. A bit more expensive, but still a lot cheaper than a Lupine light. I guess yo'll get a nice 45 W halogen eqvivalent night O lamp for ~ 200 eur
