Beurer Compact Daylight Lamp White TL50 "Light intensity 10,000 lux, UV and flicker free Uses LED energy and space saving technology " Exceptionally uniform brightness from the 25cm diameter light area "Medical product Easy one-touch operation" When the hours of daylight are noticeably decreased in autumn and winter and we increasingly stay indoors, the lack of light may negatively affect our mood and sense of well-being. This is often described as Winter Depression. The symptoms can present themselves in a number of ways, such as depression or subdued mood, loss of appetite, listlessness and lack of energy, difficulty concentrating and generally feeling under the weather. The cause of these symptoms is the fact that sunlight indirectly controls the production of melatonin, which is released into the blood only in darkness. This hormone tells the body when it is time to sleep In the months when there is less sunlight, production of melatonin increases, thus making it harder to get up in the morning and increasing our feelings of sleepiness. In addition, light deficiency also hinders production of the happiness hormone, serotonin. By using the Beurer TL50 daylight lamp immediately after waking up in the morning (- i.e. as early as possible), you can help stop the production of melatonin, thus countering sleepiness whilst improving your general mood. Normal electric light is not sufficient to compensate for reduced daylight - even in a well-lit office the luminance level amounts to around 500 lux. The Beurer TL50 provides a bright light intensity of 10,000 lux, thus compensating for the lack of natural sunlight, and yet the output of radiation beyond the visible spectrum (infrared and UV) is so low that it is harmless to eyes and skin. This SAD lamp offers exceptionally even illumination, and meets the requirements of the European Directive 93/42/EEC and 2007/47/EEC Medical Devices as well as the Medical Devices Act. Uses LED energy-saving technology. n/a
