Actually his visual is incorrect. These light designs have at most 2 LEDs, you can run two in series so the current draw is roughly 20ma. 900/20 = 45 hours.
Not exactly a "plasma screen" load on the Reader's battery.
Power sourced from the Reader would be regulated so all you need are 2 LED's, a drop resister to set the ma's and a connector to provide a nice stable light source.
