Customer Reviews:

• projection clock: Gave this projection clock as a gift after reading the blue light might make it difficult to sleep. My son loves it and does not have a problem with the blue light. However, this particular clock loses 6 hours every evening. It comes back correctly in the morning. We are planning to contact the seller about this problem. Will try to update this review at a later. time.
• cool device with fatal flaw: bright blue light: This is a neat clock. It comes with an outdoor temperature sensor, so you can look up on the ceiling from your cozy bed, and see how cold it is outside.
  
  This unit's projection is on the bright side, however. Since we bought it, I had a lot of trouble sleeping. I don't know if the clock is to blame, but after we returned it, I slept better again.
  
  Of course, there is well established research that shows that cells in our eyes are very sensitive to blue light, and the that color promotes wakefullness by interrupting melatonin production (google search for "effect blue light sleep".. Science Magazine has a good article). This circadian cycle is how our bodies know when it is day or night.
  
  You'd think Oregon Scientific would stick with non-blue colors to keep from disturbing peoples sleep. Even my wife had trouble sleeping, and she never does.
  
  The problem was bad enough that we returned it after about a month. Our model with the red projection light is much more appropriate for night time.
