Unfortunately, the lamp lasts initially what it promises, but not for long by. It is well lit, reminiscent of the good old light bulb, has a great viewing angle and also still a pleasant color temperature. Still, she does not come out with me on 1 star, because their life exactly after 8 months ended (normal daily usage of 1-3 hours). Now 14 gone and pollutes the environment with meaningless electronic waste. Sad
