So bought and tried out immediately. The first light bulb turned into the socket, the lamp is turned on and after half a second the lights went out. Bulb broken. The Broken removed and replaced with a new light bulb, the same game was repeated. Then I looked at the product a closer look and realized that I purchased Honsel table lamp is apparently only compatible with energy-saving lamps and does not match the item description available on Amazon. On the inside of the funnel sticks a sticker with the message "E14 Max 11W ESL" and the same is so also on the box. I finally bought the shop around the corner an energy saving lamp and this works in the table lamp no longer occasionally fail.
With "questionable processing" I mean really only a small optical defect, because the base of the table lamp is pretty messy painted. Keywords: many small bubbles.
In sum, I am quite disappointed with this product because I bought it directly from Amazon and the product description so colossally wrong. However, this is also the first time in my more than 10 years, I am Amazon customer that me something has happened. Sending back I will table lamp but not because it is not worth the trouble to me and with the nachgekauften Energiesparlampe now everything works correctly.
