"The Best Light Therapy Lamp"

The low intensity Lo- LIGHT therapy lamp, which uses a patented GreenLIGHT technology, was found to be the "best phototherapeutic device" [light therapy lamp] in a comparative study with other light therapy devices conducted by the U.S. Air Force and DRDC, the Canadian Defence Department's R&D Centre. This study is part of a multi-trial study aimed at improving the alertness and performance of night shift workers, and was conducted to select the optimal light source for regulating circadian rhythms of night shift workers in the workplace. The study found the Lo-LIGHT provides the most efficient form of light therapy for chronobiological applications and Sunnex Biotechnologies low-intensity Lo-LIGHT lamps were selected to be used in the on-going development of this night work adaptation program. The authors concluded: "The [Sunnex Biotechnololgies] light tower was the best device, producing melatonin suppression and circadian phase change while relatively free of side effects". See Ref

The results of this study are consistent with a number of independent studies that have demonstrated that at intensity or brightness levels normally used for indoor lighting, the Lo-LIGHT has the equivalent effect as 10,000 lux of white light. In this study, when comparing the phase shifting capability of phototherapeutic devices, the authors found that less than 10% of the light intensity(energy) from a Sunnex Biotechnologies Lo-LIGHT twin tower unit was substantially more effective than that from a light therapy lamp that emits primarily blue light. (the Litebook®) The GreenLIGHT technology was found to be at least as effective as any of the other devices tested, even though Lo-LIGHT lamps provide only a very small fraction of the light intensity provided by the other phototherapeutic lamps.

This is in marked contrast to findings of studies studies with light therapy lamps that emit blue light (479 nm) or white light enhanced with blue light (465 nm), which have been found to to be no more effective at shifting circadian rhythms than bright polychromatic (white) light therapy lamps. more at Bright Light Therapy and Blue Light Therapy vs GreenLIGHT Therapy
