I have this one and like it very much. It has to be clamped to something, but it expands quite long and is highly positionable. I've used it in a couple of locations in my home and have never had trouble getting it exactly where I wanted it.
I may have seen your post too late to be of service, but I've been very happy with this one: https://www.amazon.com/dp/B07C3CLJWV?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1 Very maneuverable, not heavy, love the ability to change the levels, and the lid to prevent it from starting a fire when not in use!
Came here to say lighting too! Take a look at how she works - an Ott light (floor size or table size) might be most useful, or she might love this, if she has someplace to clamp it on. It has been a game changer for me because I get both light and magnification in one source, and I can move it to exactly where I need it yet be hands-free.
