Question: Is the lamp base weighted well?  Will the lamp tip or lean over if you adjust the light to any angle or extend the arm out to it's maximum capacity?
Document: This is a wonderful light. It provides exactly the kind of light I need for the close hand work I do. I highly recommend this light!
This is my second lamp of this style and model. i purchased the first one locally for my husband several months ago. I paid almost $60.00 more for that one. It was so helpful for him, reducing eye strain and thus allowing him to read more, that I decided to try to find another one for myself. I thought I was OK reading with just the regular lamps in our living room until I sat under my husband's Ott Lite. What a difference it made!
I understand it is an investment, but you only have one pair of eyes and the older you get, the harder it is to focus without eye strain and the consequential headaches that can accompany poor lighting. I'm glad I purchased these lamps and highly recommend them to anyone who loves to read.
