It’s what I needed
I haven’t tried any other book lights, so this was my first purchase. So far I’m happy with it. I really only use the highest setting of the 3 levels of brightness, so I’n not sure I needed the brightness options. And I have found on larger books I end up adjusting the light arm a little when I move to the opposite page. But overall, I really like this little light, and works for the pretty limited time I spend reading in the dark before sleep.
