A projection alarm clock shines the time on the ceiling or a wall so you can read it without lifting your head or reaching for your phone. Most have a rotating projector arm, a brightness control and a USB port. The projection is usually larger and clearer in a dark room.
The six clocks below range from a simple USB-powered digital clock to a Braun model that projects only when plugged in. Sizes, displays and power come from each product’s listing page. We have not used these clocks ourselves. Brightness and clarity depend on your room.
