Best Buy Homedics SS-5500 SoundSpa Radiance AM/FM Alarm Clock with Time Projection, Light, Sound and Timer

Over All Rating Reviews :

If you are an engineer, or mechanically inclined, the poor human factors design - namely, the interrogation-light-in-the-face, so amply described in previous feedbacks - can be corrected. I cut-up a 1mil-thick black trash bag and placed it over the clock display, as well as the projection LED. This reduced light throughput by 2/3 and made the product usable in a darkened room. That's only a stop-gap solution to prevent excessive light pollution in the bedroom. I gave this product one star, because the excessive light output makes this bedside clock unusable for its intended purpose.
To be deserving of 5 stars, this product needs two changes:
1. It needs red LEDs, because human factors engineering research proves that humans respond to light frequencies above red with increased alertness, not something you want to achieve constantly with a bedside clock.
2. A photo sensor, coupled to a solid-state dimmer inside the unit will assure the right LED display and projection lamp light emittance, especially as the bedside lamp starts brightening.
