The lamp does not hold nearly what it promises. That she does not reach the specified 400 lumen, a need to be aware before buying. But it's a Funzel, I did not expect. I ordered along with the smaller version with the specified 300 lumen. The smaller is much brighter! And also does not serve up a LED Lenser p 5, which is indicated with 120 lumens. 40 lumens would as well have been a realistic indication!
