I have three magnifiers. One is a lens with a circle bulb under it. It's a swing arm lamp so it needs to be attached to a table. The other is a lens on a stand, with LEDs providing light underneath it - it was less than $100. They provide better light than the Ott light with a lens, which I also have.
Of the three, I like the swing arm the best because it's stronger. However, I have no place to attach it so I use the floor stand one now. The Ott light simply doesn't provide enough light through the magnifier to make it worth using.
