Didn't know about the health benefits, but I have two OTT lights-one has a base for sitting on the desk or table and the light can either be put in the base, or taken out and stuck on my quilting frame. It has a flexible arm so I can position it as necessary, and an attached magnifiying glass (which I can't get used to!). I also have a smaller one for my table with a gadget caddy that I find really useful. I can't hand-quilt or hand-applique without it!!
