Query: A ray of sunshine

Just to take a moment to address a few of the concerns from previous reviews: The light can be made to stay on after the 'wake up' cycle, by pressing the alarm on/off button. The reading light also stays on for as long as you'd like -- the snooze button is used to turn the light on and off. It also works with any light that can be dimmed -- incandescent, xenon, halogen, etc. It just works and works well.
