My wife who loves to read in bed after I have gone to bed, has tried many, many book lights over the years. The complaints have been many about each one, and pretty much the same. Small circle of light, have to move it from side to side to see good. So last Christmas I went on an internet hunt for the ideal book light. After a few days of research, I decided on this one for her. Now 7 months later she wants me to buy one for our daughter, and a spare for her (in case I lose or break it) cause she says could not live a night without it now. True story. It is bright and evenly covers an area of two pages of a large book without trouble, no hot spots. Seems to be the perfect book light. Battery life is excellent with the LED bulbs.
