This lamp is really well done. The design is neat, efficiency is real thanks to its different lighting modes. It is thus possible to best adjust the brightness needed. The LED lamp gives no fatigue, is in my opinion an ideal extra light for reading or working. The USB port also allows to recharge their smartphone or tablet. In short this is a very good product, a pleasure to use every day and which has done its job. Value for money quite correct. Definitely recommended.
