SunRise Clocks are designed for those who do not want the white noise feature. It is derived from medical research on light and human behavior.

In the early morning, the biological clock is sensitive to low intensity light. So, waking to a slowly increasing light can result in a smoother, more natural transition to wakefulness. It features an audible back-up alarm, the ability to set dawn and dusk cycles of 15, 30, 60, or 90 minutes, display brightness controls and more.
