    I truly cannot believe how I feel this year! I use the Northern Light desk lamp every morning for twenty minutes. This is the first time in decades I feel energetic, awake and full of life. I normally suffer from the winter “blahs”…ok lets just call it depression, but not this year. Thank you so much for a life altering product!

    Been using this device for over twenty years. I remember when I first used the SADelite , a loaner from a CMHA Doctor, after three days of use I asked my Father for a loan to buy it from Northern Light Technologies, as I had my sense of humour back in February when usually I would be practically catatonic. I have been using it and the travelite when I travel ever since.

  4. Brenda Nichols

    I have been using my Northern Desk Light for at least 25 years. I remember when I opened the box and plugged in the light. I screamed with excitement because it was that light that I point my face towards. The light that brings joy. It was the best purchase I have ever made.

  5. Joanne Armstrong Ph.D.

    I highly recommend the Northern Desk Light, very well made and reliable. Originally I purchased the desk lamp while living in northern Wisconsin where there are many cloudy winter days. There, I used the lamp twice per day in the winter, in the morning and again in the early evening. Eventually I moved South and continue to use the lamp each morning for 20-45 min. As a clinical psychologist, I recommend Northern Lights Technologies products to many patients, family and friends. I could really use an additional demo lamp at the office for patient and staff use. Currently, I am seeking replacement full spectrum light bulbs. Yes, I am a big fan of Northern Lights Technologies.
