Review on Projection Digital Alarm Clock: Ceiling Wall LED Clock with USB Charger and Loud Alarm for Heavy Sleepers, Kids, and Elders, 180° Projector, Dimmer, 12/24H, Battery Backup by Chp Rodgers

I switched all my LED and projection clocks from red to blue as I had eye problems. The red LEDs were too bright and many of my watches were in their first year or so. I've been using projection clocks in my bedrooms since I had spinal surgery and I have a hard time turning around and seeing the time. I sleep lightly because of the pain and once I wake up it's almost impossible for me to go back to sleep. So these things are sent from God. Blue is easy to see and not very bright, and I sleep better with it than red. I have a clock on my surround speaker, so I don't see digests, so brightness doesn't really matter. If you want a good clear blue LED projection clock this is a great clock for the price.
