The most common device used for bright light therapy is a fluorescent light box which produces a light intensity of 2,500 to 10,000 lux at a comfortable distance (1-2'). Light box intensity ratings are always at a given distance. Light weight portable boxes and those mounted on a stand are available. Full-spectrum light is not necessary since intensity is most important, but a balanced-spectrum light minus UV-B emissions is considered ideal. Fewer headaches and eyestrain are associated with using balanced spectrum light. Most light boxes cost from $250 to $525. Light visors which use a battery pack, are worn on the head and allow for mobility. Light Visors appear to be at least as effective as light boxes because the light source is close to the eyes.? Dawn/dusk simulators are rheostat timers which are used in conjunction with a bedside lamp. These units gradually turn on the lamp light over a preset or variable period of time. Dawn/dusk simulators appear to be most effective for those with mild symptoms, for those who did not succeed with bright light therapy, and for those who have success with bright light therapy but still have difficulty waking up.
Our mission at Light Therapy Products has always been to make sure that people get the light that best suits their individual needs. We also try to make sure that people know how best to use the lights we sell safely and effectively. That means trying to get information on the site and answer the questions we get over the phone. But we know that we don’t know it all and we can’t put all the information about light therapy on the site. So we decided to create this forum.
