Flashlight "Fuloon" non zoomable 7 LEDs.

I bought this flashlight, hoping to get a very high brightness of 8500 lumens.
I tested its power at night, it lights perfectly, but its 8500 lumens, advertised, are not waiting for you!
Just, just 2,000 lumens, use full power, the price of 42 euros, is not justified, no accessory is provided;
apart from his belt pouch, which is not like the model presented and not functional.
I usually use high power flashlights in my security-related business, this material is not complete, expensive and not very effective. I recommend it for occasional use, but not recommended for professional use with Li-ion batteries of 3.7 volt, 5000 mAh to 7200 mAh (times 4 to 6 hours of use).
