A clinical study led by sleep researcher Dr. Dieter Kunz at the St. Hedwig hospital in Berlin has provided evidence that the biological effectiveness of LUCTRA® workplace lamps is based on the production of the hormone melatonin. LUCTRA® is the first workplace lamp for which such systematic evidence has been established.
The study was conducted in July and August 2014 with 16 participants. In the test period, the test persons were each exposed on five evenings to one of five different lighting situations. The biological effectiveness of the lighting was measured on the basis of the melatonin content in their saliva. In medicine, the sleep hormone melatonin is currently recognized as the most reliable indicator for the influence of light on human beings. In addition to saliva samples, the test persons gave assessments of the visual comfort of the various lighting situations.
