By using the Beurer daylight lamp TL50 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 daylight lamp 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.
