The Sony cover with the built-in LED reading light is rated for about 19 hours of use with a single AAA alkaline battery. Have you found this estimate to be realistic? It seems too good to be true.

Is it ok to use NiMH batteries with LEDs? In the past I've burned out small conventional reading lights by using NiMH batteries instead of alkalines, and wonder if LEDs are also at risk of burning out with NiMH batteries.
