What is LUX light anyway?
LUX Pronunciation: (luks), —n., —pl. luces Pronunciation: (lOO'sEz).
A unit of illumination, equivalent to 0.0929 foot-candle and equal to the illumination produced by luminous flux of one lumen falling perpendicularly on a surface one meter square. Symbol: LX. Also called meter-candle.
Basically, it's a unit of light measurement. Higher the number, brighter the light source.
What is the importance of the 10,000 lux and distance rating?
The 10,000 lux measurement is important in light therapy to judge the effectiveness of any particular light box or lamp. Since the 1970's, studies have shown that light therapy is effective when a person is within a 10,000 lux brightness range of light for twenty to thirty minutes. Our light box has a 10,000 lux light therapy range at 24 inches. This is important to consider when shopping around. Many lamps boast of 10,000 lux light, but fail to mention at what distance this is from the light unit. For example, a light that has a 10,000 lux light therapy range of twelve inches means that either you would need to sit within a foot from the light for ½ hour, or at a more comfortable two feet you would need to spend one hour to get the same therapeutic effect. You will need to consider what works best for your lifestyle when making your decision.
Light therapy boxes built with some UL-listed parts are not the same as those in which the whole light box has been UL-tested and listed. If a company says it uses UL approved parts for their therapy lights, this means the whole light box was not tested. For safety sake, verify this before you buy. It's also against the law to sell electrical appliances that are not UL-listed.
At Alaska Northern Lights, we base our lumen light therapy and light box information on a variety of accepted scientific studies and not on the opinions of a few individuals. Research has shown that in light therapy, the light's intensity is the key.
Actual Client Testimonials
"I've lived in Oregon for 3 years now after having moved here from Arizona. Every Winter is very long up here and has been very difficult for me. After doing some research and spending a pretty penny I bought the 'Carribean Sun Blue' light box. I used it for 5 months with no result. I only found the color and brightness rather irritating. After doing more research I purchased your light box, rolling floor stand (a great accessory!), and storage bag. The results were darn near immediate. I'm never going back. I enjoy using this product every morning for about an hour while on my PC. My outlook has improved and I have begun finding it easier to get out of the house and do things. Something that it difficult for people suffering from depression. I am convinced that I am not experiencing a 'placebo effect' with your product as I have tried out another light box to no effect. Thank you so very much. It was worth every penny that I spent. Wish I had picked it out sooner."
