Norther Light was the brand of Lightbox that my shrink recommend to me and I haven't had any problems. There may be cheaper options, but I haven't tried them. So far, the box has positively impacted my mood. But you should consider a light box based on a doctor's recommendation, not on Amazon reviews. As such, I'll not review the effects of the box but the quality of the product itself.It's durable. It's stood up to travel so far. The stand is easy to screw and unscrew, yet holds when you need it to. The light is bright, but it's supposed to be. The nice thing is that it's diffuse so when I use it, with the box placed about a foot away from my face and off to my right, it doesn't bother me.It doesn't overheat, either. I keep it on for well over an hour, and it maintains a reasonable temperature. It does get warm, but that's all the more reason for my cat to love it. That is, I use it to treat MY SAD, my cat just happens to love to bask in its glow with me.Again, I have NOT tried other light boxes, but I haven't had to. This one has worked just fine.
