Lamp Light is a very simple app based on a simple idea - utilizing the power of your laptop (powerbook, ibook) display to emit bright reading light. It's simple - a screen displays pure white light, and you can choose your settings from battery saving low, medium to high. It's also useful when traveling on long plane flights - use Lamp Light instead of the overhead light so as not to disturb all the passengers around you trying to sleep - and other low light conditions.
