I cannot evaluate the therapeutic value of the lamp because I have only been using it for 2 weeks. I do love the lamp itself. it is a good size for my desk, The quality of the light is great, bright without glare, and the intensity of the light can varied substantially.
It took some time to get used to sitting so close to it for the full effect but I’m very comfortable with it now. I set it up right next to my bed and in the morning I just pull it close and play on my phone for 30 min while laying on front of it. It makes mornings so much easier.
I purchased the 24" x 7.5" light and love it. I set it up on my counter each morning and then cook my breakfast, eat, and do the clean up while in its range. Really enjoy not having to sit in front of a light for 20+ minutes.
Unbelievable results! I am so grateful! Great product!
