Input:
This book light is excellent.  I have problems with blurred vision and need very bright light to see to read most days.  This light does the trick for me.  Unlike the smaller 1, 2 or 3 lights this one covers both pages of the book and I don't have to keep shifting it around.  Would definitely recommend.
