Read In The Dark With The LED Page Light
If you have to read in the dark for any reason at all, this LED Page Light would definitely come into handy.
AAA batteries power the four LED lights illuminating the lens. The transparent panel of the device traps the light within, protecting your eyes from being blinded by any direct light while allowing for a good read without disturbing others.
Battery life of the product is stated to be at 40 hours and it sells for US$25 at the Gadget4all store.
