Harvard University Selects Low-Intensity Lo-LIGHT Lamps for NASA Study


Lo-LIGHT lamps in NSBRI* study at Russian Institute for Biomedical Problems

Harvard University selects Lo-LIGHT lamps to evaluate lighting interventions for combatting the negative effects of sleep disturbance in astronauts in a NSBRI study. The study was conducted in collaboration with the European Space Agency at the Russian Institute for Biomedical Problems. It compared the effects of Lo-LIGHT lamps using the GreenLIGHT technology with other types of light sources on performance, alertness, and mood during the night shift.

The Lighting Intervention Study, with lead investigator Dr. Charles A. Czeisler, Director of the Department of Sleep Medicine at Harvard University, compared the effects of different wavelengths of light on performance, alertness, and mood during the night shift. The trials consisted of two different wavelengths of light in the green spectrum, a shorter wavelength green light [the Sunnex Biotechnologies GreenLIGHT], and a medium wavelength green light(545-555 nm), as well as a control condition with longer wavelength (620 -690 nm) red light. Crew members and mission control personnel participated.

Studies to Improve Performance and Alertness of Night Shift Workers for NASA

From their examination of human sensitivity to visible light wavelengths, Harvard found "new information about the peak sensitivity of the human circadian system, determining that the most efficacious specialized light source should have a peak near 500nm (as opposed to ~470nm as the lamps produced by Philips Lighting, Eindhoven, Netherlands, as originally proposed), and therefore identifying such a new specialized light source for our studies; retrofitting our laboratory with specialized lamps (manufactured by Sunnex Biotechnologies, Winnipeg, MB, Canada) with a peak sensitivity near 500nm."

General Applications

Low-intensity GreenLIGHT technology has application for shiftworkers, jet travelers and any personnel who need to shift the timing of their biological rhythms. It can be adapted safely and comfortably into almost any work environment. Potential users include first responders, hospital staff, air traffic controllers, power plant operators, people in the transportation industry and on military operations.
