This lamp was a Christmas present for my husband's home office.  It came a little early so our holiday guests will get to see it. Thanks. It is much heavier and well made than it appeared in the catalogue. It is very stable.  It is great for desk work because you can lower the light right into the work space or raise it to light the whole room. Everyone comments on its  unique design. Their first question is "where did you find it?"  It is an engineers delight.
