I am disappointed by this lamp - they came at the same time defective: the on / off switch was without any resistance and the lamp did not work, of course, so on.
Have this lamp already purchased several years in operation and now yet another. As a desk / computer Lamp ideal and also fairly compact. The height adjustment here is also perfect. Recommended!
The lamp works as advertised and is also nice bright Dicker disadvantage. Partly very loud humming in diverse tonlagem when one reads for example a book in peace ...
