After opening the original packaging, the new Waterstrøm flash-lights are only activated when they get wet. To do this, simply immerse the torch handle (or PowerBank barrel) in a liquid containing water for around five seconds, to allow the device to absorb sufficient moisture.
If necessary, you can also pour the liquid directly onto the handle of the Waterstrøm flash-light. Activation with water is always preferable, but in an emergency, any liquid containing water will do. The lamp can therefore be activated in a simple glass of water, in a river or in the sea, but also with fruit juice, beer, urine, etc.
Once humidified, you will have a lighting cycle of around 17 hours (lighting power: 67 lumens; beam range: between 34 and 50 meters). However, if after use you place the lamp on a radiator, for example, the lighting time will be shortened, as the evacuation of moisture will have been accelerated.
And if you don’t re-wet the Waterstrøm lamp, the oxidation won’t be reactivated at all, and the lamp will retain its full potential. So you’re guaranteed to have a lamp that’s ready for use on demand.
Technically speaking, and in simplified terms, here’s how it works: the lamp handle contains several metals with different electrochemical potentials. When the system is immersed in water, chemical reactions take place between the main inner metal element , the water stored in the absorption and retention means and the outer metal sheath.
These chemical reactions result in the concentration of negative charges (negative pole) in the main inner metal rod and positive charges (positive pole +) in the outer metal sheath. It is due to the existence of this difference that a voltage is created between the main inner metal rod and the outer metal sheath, triggering the erosion-corrosion process of the inner metal rod; the latter then begins to lose electrons from its core, so that by connecting a power source – an LED source, for example – a flow of electrons is created from the said inner metal rod to the outer metal sheath, this flow of electrons being electricity.
The oxidation of the inner metal element is due to the positive oxidation potential difference, since this element has a higher positive potential than the outer metal sheath.
Please note that without opening the original Waterstrøm packaging (tin can), our flash-lights are guaranteed for 100 years. This means they can be stored indefinitely in a dry state, with no loss of efficiency.

Love the idea of these flash-lights! For night anglers, this could make a huge difference in terms of convenience and sustainability. I wonder how the light intensity compares to traditional options though?
The idea of a battery-free flashlight is pretty intriguing! I can imagine how useful this could be for those late-night fishing trips. No more worrying about carrying extra batteries!
Waterstrøm’s approach to outdoor lighting is refreshing, especially with no batteries required. It really highlights the shift toward more sustainable and practical solutions for outdoor enthusiasts.
The idea of a flashlight that doesn’t require batteries is a game-changer, especially for anglers who spend long hours on the water. Not having to worry about dead batteries or carrying spares makes night fishing or early morning trips so much easier. I’d love to hear more about how it works in real-world conditions—does it hold up well in wet environments?
Battery-free lighting sounds like a real game-changer for night fishing trips. Would love to hear if anyone’s tried these on multi-day excursions and how they held up over time.
