Get ready to wake up with the Sharp Digital Alarm Clock with Jumbo Display and Nightlight. The alarm clock has a 1.8” tall red LED time display， making it very easy to read from across the room. The easily accessible keyboard style controls make this one of the easiest alarm clocks to operate! The jumbo nightlight offers enough light to see but subtle enough to prevent disturbing anyone. Leave it on all night， or turn it on easily when needed. This alarm clock plugs into an outlet and offers an optional battery backup (requires 1 x 9v battery， not included).
