Full Spectrum

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

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!

Client Review

"My house receives very little natural light due to poor window placement. This causes many problems for me because I suffer from seasonal depression and bipolar disorder. When the seasons start to change and the daylight hours become shorter, I know that a dark depression that will last til spring is on its way. I dread it each year.

This past year I discussed treatment options with my doctor and she recommended I look in to getting a light box. I did an extensive amount of research by reading many websites and online boards for people who suffer from the same problems I do.

Over and over again I found the company recommended most was Alaska Northern Lights because they had the best quality, best reputation and best customer satisfaction. I love my light box and feel I have gained a new life during the winter months. I don't have to suffer any longer.

I am so very thankful for my light box from Alaska Northern Lights. It is one of the best investments for my health I have ever made."
