Where to Purchase a Good Light Therapy Device

It is important to choose a reputable company that can provide a quality product at a good price, with reliable service over the long term. Consumers can have confidence in companies who are members of the industry trade group, the Circadian Lighting Association (CLA) because all CLA member companies:

- Have been in business for at least twenty years

- Offer a 30 day, no-questions-asked money back guarantee

- Make products to the highest quality standards, proven by independent testing

- Meet or exceed international safety standards

- Support research and patient support organizations

- Understand the needs of people who need light therapy

Buying Guidelines

When you are considering buying a bright light product, do your home work, and ask questions. To learn more about bright light and "winter blues", consult a knowledgeable health professional and get some library books on the topic (Dr. Norman Rosenthal's Winter Blues is a good place to start). When you are ready to start talking to companies, ask some of the following questions:

1. Is your company a member of the Circadian Lighting Association?
2. What specific products do you recommend for me? (describe your situation)
3. Do you have a 30 day money back guarantee program? (stop here if the answer is no)
4. Does the product filter out UV? (many experts feel UV may be unsafe)
5. Has this product been tested for effectiveness in clinical trials?
6. What is its lux output at what distance? (ask for output levels at a realistic usage distance, say 20 inches)
7. How long has your company been in the light therapy business?  (the longer the better)
8. What is the warranty coverage? (a warranty of at least one year is a must)
9. How big is it? (size and weight)
10. How much does it cost? How much for shipping? Bulb replacement cost? Extra costs for stands, cases, etc.?
