Query: Weak light

OK product, but the beam is weak. It is adequate as supplemental lighting for a book (i.e., when you have overhead lighting) but not enough if you are reading in the dark or in low overall light environments.Definitely NOT recommended for use with large books, like textbooks. The light coverage is simply not adequate and the neck is not long enough to let you compensate for this by adjusting the beam down the page as you read.The other thing I don't like is the light cover has that clear bottom that doesn't shield the beam from your eyes when placed at most angles over the book, leading to eye strain (think reading under an incandescent bulb without a lampshade). A much better light is the Mighty Bright.02/15/2008 Update: worse than I thought. Would rate less then two stars but can't edit the original rating. This light is too weak, the clip is bulky but not strong. Threw mine away because it serves no purpose!
