In reading other reviews I was a little worried by the product quality and power of the led. On the side of the light, it's true that you can almost light up a room with the lamp, however thanks to the flexible arm design of the light can be directed correctly and avoid impeding our partner. Before I had another less powerful LED lamp, let's say I could read but it was too tiring for the eyes, I much prefer this lamp with its good lighting because you can always arrange to be discreet. Then, the product quality is excellent, the arm stands firm but is very malleable, the clip clings perfectly well. I am very happy with my purchase, I will have to wait until the life of the battery to be 100% sure but I gave it a priori 5/5.
