It is a flashlight and a lantern. You just pick which one you need.
You can use it to light up a garage, around the house, while camping, during an emergency, or when you are facing a power outage or severe weather.
By expanding the barrel, the Hydralight becomes a lantern that is hands-free. This gives you more light to a bigger area. Using the hand held light, you normally need one hand on the light at all times, but this unit makes it hands-free so you can work. As such, you can change a tire with this light by your side, or work on repairing your car.
You can switch it on or off just like you would a normal flashlight. Once it has been fully charged, it works for up to 100 hours without needing another re-charge.
What the company fails to explain is how long it takes for the unit to charge completely. Without this reference point, it is difficult to know how well the unit will work in emergencies or while camping / hiking. If it takes an entire night to recharge, then you are left without light. Conversely, if it only takes a few hours, then you can easily use this light while you are facing a power outage or in the middle of the woods.
The unit itself is about the size of your hand, and the light bulbs inside are even smaller. This means that while it might be effective in holding a charge with water alone, it does not give you a big coverage area or a bright light. Additionally, the unit lacks strobe functions or emergency light options like alternative flashlights / lanterns.
The Hydralight works by way of a special water based battery. Likely it is a magnesium oxide battery, one which is water powered by a chemical reaction. Regular chemical reactions keep the power on and the light bright.
Take the fuel cell out of the light.
Put the fuel cell inside water, fully submerged.
Watch as it starts to charge.
Then remove it from the water and put it back into the light.
Start using the light as needed.
The only other alternative on the market is the American Red Cross Blackout Buddy. This light is not meant for regular recharging, but is instead an emergency light that you can use for 72 hours straight. Said unit is environmentally safe, using a magnesium-oxide battery that is activated by water. You can pour water into the bottom of the unit and watch as the three LED lights turn on.
After you have activated it, the light will stay on for 72 hours. If you see it start to dim, you only need to add a bit more water. There is an on/off switch though, if you want to turn it off at night. Working even if entirely submerged in water, this unit is great for all weather.
