The NorthStar 10,000™ is a broad spectrum light. With our brightness level of 10,000 lux at two feet, the NorthStar 10,000™ is effective, easy and safe to use!
Full spectrum light bulbs are made to try to imitate natural sunlight, and like sunlight, they also produce UV rays. Typically full spectrum bulbs have a Color Rendering Index (CRI) of 90 or above (100 is actual outdoor light) and a kelvin temperature of 5,000 or above. Full spectrum light is described as having a purple or bluish cast. Most light box companies using full spectrum light bulbs now block these UV rays through their diffuser screen, it's good to check to be sure.
Broad spectrum light boxes are described as being as close to full spectrum as you can get without the UV rays. Typically they have a CRI. of around 82 and a kelvin temperature of around 4200. Broad spectrum light bulbs are described as being a pure white light. Most light box companies use a broad spectrum light bulb so that there is no danger of UV rays.
Light therapy with a NorthStar 10,000™ can make your winters happier, healthier, less stressful, brighter and UV FREE!

"A patient of mine was telling me how he used to get so depressed and lethargic in the winter until his wife, in depression, bought him an Alaska Northern light. After asking several questions, I was convinced that it could help my husband too. I wasted no time and ordered our own light. After using it for a month, my husband swore it did no good. I talked him in to using it for a whole season and he is glad I did. By 7 weeks of use he was having second thoughts. By the end of 3 months of use here in the Willamette Valley he had completely changed his mind. We are now just starting the 2nd season with the light box and I am looking forward to a good winter, as when one person in a household has SAD, it will affect the rest of the home to one degree or another. I do not personally have trouble with SAD but I do have to admit that getting exposed to the light on a fairly regular basis, I too get 'energized'. In fact my husband says that it 'over energizes' me! I don't mind at all. The light is what I call 'cheery' :) Thank you so much!!! "
