BUT: Unfortunately, this lamp, unlike mentioned several times in the article description, NO dimmer. The seller was this seemingly unaware or do not care. Because after appropriate mail traffic and demand / notice on this issue, was denied that a dimmer is mentioned in the article description. After I had this proved via hardcopy, it was indeed consulted and apologizes, but still not adjusted the product description.
So be careful when buying, this lamp has no dimmer and 5 x 40 watt can then still be quite bright and dazzling fast without dimming.
