Question: Is this lamp dual voltage (220v & 110v)?
Document: The lamp I received was the product I ordered.However, the dimmer was smashed and didn't work at all although the potentiometer seemed to be OK despite of the fact that the plastic holding it was separated from the upper half - completely broken.The socket was receiving around 5V+ or jumping directly to the mains voltage with no values in between. When off it still measured ~2V on the socket.The lightbulb was fine but it would never light up in its lamp socket.
Other than that, the lamp is really nice.
Definitely recommend this lamp!
Beautiful Natural Lamp!
Love my lamp everything I expected
However, this particular lamp was in very poor condition.
Please enlighten me on the secret of a successful lamp purchase.
:) Once the lamp was free from packing materials, it was ready to go!
In contrast, my lamp is more polished...both look about the same. The color and shape are acceptable.
Just recieved the lamp. plugged it in for the first time and the bulb exploded!! !Awful!
