I got one for Christmas, and I just plugged it in and OMG it is bright!!! It says to have this light equal with my eyes but eat or read rather than obviously staring at it (lol) - and sit 11" away for 30 minutes a day. It has 10,000 LUX of light. Any experience with this? I still feel like I may go blind. I am trying it as I speak. I am praying this is another nail in the coffin for my depression since I moved North.
