Very useful item at a good price
This works well and is very inexpensive for its features. I like that it has a rating of up to 10,000 lux, as that is the recommended brightness for winter depression. Also, you can control the color temperature (color hue, or how much yellow/blue appears).  I don't see that it was a CRI (color rendering index) rating, and some other more expensive bulbs make a point that theirs has this; however, I have not seen CRI ratings being required for winter depression in any medical literature, so I'm ok with it.<br /><br />For color temperature, I prefer as white as possible, as that seems to give me the lift I need in the morning. The directions suggest less white if used in the late afternoon or evening  - I have not tried this, but it makes sense that you'd want as white as possible in the AM and less so in the PM, as that would imitate the sunlight throughout the day. It also has an optional timer so it will turn off automatically after a period of time,  if desired. All the settings are controlled either by multiple presses (timer) or press/hold (color temperature and brightness), which is easy, though not so intuitive. This is explained clearly in the directions, and is easy, once it is known. I like that it is LED-based, as this uses less energy and creates less heat.<br /><br />Overall, this is a nice, well-priced item that is going to be useful this fall/winter, as the season gets darker, and the sun starts coming up later and going down earlier.
