Ultrafire with lots of light !!!

Since my current bike light is not strong enough to at night to light the way, I decided a flashlight with aerobar to buy.
Shipment be commended, because after 2 days, the torch was already there, but I thought that ordinary AAA batteries can be used. Think again, and after a short search I bought this battery with an appropriate charger me a 3.7V (model 18650).
Because such batteries on Amazon are expensive with 8-12, the charger has offered.
Now the flashlight single pair words: It has 5 modes, 3 consistently glowing in different brightness levels and 2 flashing at different speeds.
So far I have only tried the flashlight 1 times, and I must say that the way diesse night really good illuminates and you can see a lot.
In the product description also states that it is waterproof, which I do not believe it is true splashproof somewhat more.
All in all a very good flashlight which can be as a bicycle lamp, with an adapter, repurpose.
