Project Time on Walls or Ceiling: The projector on the top of the digital clock projects large and clear numbers onto the walls or ceiling. It allows you to easily read the time on the ceiling rather than turning around to see the clock when you are lying in bed. The red ceiling projection light is soft and non-disturbing. The time direction can be adjusted 120° on the ceiling surface, and the optimal projection distance is 2-3m/80-12inch.Dual Alarm Clock with 2 Alarm Sounds: Simply set 2 separate wake-up alarms when you and your partner get up at different times. Perfect for occasions like sending kids to school or going to work during the week. You can wake up to a preset alarm tone or alarm radio station. The Snooze function allows you to sleep an additional 5 to 60 minutes before alerting you again.Large Screen with Dimmer: The large red numbers on the large screen are easy to read from a distance and it has 3 brightness levels: bright, dim, off. The adjustable dimmer allows you to adjust the display to a brighter setting during the day and a softer setting at night. Arc-shaped display allows you to see the time from multiple angles.
