I bought the Amazon light as well.
Not Impressed; the LEDs will not illuminate evenly.
I ended up buying this:

Full spectrum Light, with 2AA that can be recharged via USB.
(You supply your own rechargeables, USB cable and case included)
Much better full spectrum light coverage; my Kindle and Eyes love it
