She is very strong and very good quality.
When I passed the lamp control, I thought she had a lot enlighten, but 8500 lumens, it was not possible. When I received my lamp and put the batteries (which I had also purchased from Amazon), I was amazed. I would never have believed that such a lamp can illuminate much. It's great. I have no way to measure if it really is 8500 lumens, but it did indeed seem to be true.
We must put the positive pole of the battery to the lamp head (where the light comes out) and the negative pole to the bottom, where is located the button to switch on, off and select the operating mode.
It is off or glows fully pressing the button, and choose the operating mode (high, medium, low light, flashing or not) by lightly pressing the same button.
