The new model 320 is the brightest BlueMax™ dawn simulator. The integral lamp mimics a natural morning sunrise or evening sunset using long-life LED bulbs. Set to suit your own pattern of waking and sleeping. For dawn simulation it will reach full brightness at the wake up time you have chosen. At that time you can wake to an audible alarm or choose to wake with just the dawn light simulation. This unit has three cords for use in the US, EU and UK and works on DC current.
