Question: Is this lamp cordless?
Document: I purchased this lamp and a coordinating lamp for an office lobby. The lamps are beautiful and we've had several compliments on them.
All in all this is a great lamp, high quality, made very well, and looks great in my living room; I bought two of them.
This lamp is awesome! I bought two. I am glad I bought these!These lamps arrived well pack and on time.
I love this lamp! It is a piece that stands out and it is a taller lamp but that is what I like. Would love to purchase another hopefully soon...You will love it.Price beats the other places I looked as well, Amazon has great prices! !We have made several purchases very happy.Thanks Amazon!! !
I loved my first lamp I got from the Amazon.com site but love this one even more. It adds a beautiful touch to the new end table I have it on next to the couch. It is one big table lamp and almost has a Victorian look to it. Worth the money paid and gives the room a classy look. You won't be disapointed with this lamp.
This is a beautiful lamp! The lamp ships in two boxes, one for the base and one for the shade. Both boxes are designed to protect the lamp and shade very well and they arrived with no damage. At first I thought this lamp would be too tall for my end tables but they fit in just fine. The color of the glass urn is a combination of a golden copper/bronze brushed over a base of medium yellow gold; there are no red tints. So look at the close up pictures carefully.
They were a little taller than I expected them to be...couldn't visualize 38&#34; I guess...LOL...but I do like the lamps a lot!
Answer: yes
