The lamp is really huge! Both as regards the dimensions, as also the luminous efficacy on. Even better, however, is the effect on mood. Like so many others, I have been struggling during the winter months, with fatigue and bad mood (New Germany: Winter Blues, that sounds almost jovial). Because it seemed to me the concept of ornamental lamps interesting, I have dealt with the issue. As I stated, these are nothing more than more or less elegantly packaged fluorescent tubes with daylight spectrum. So I went in search of an appropriate energy-saving lamp. Find anything I'm with the Tornado Philips. To test me were all 22 rather than over 100. In addition, I would in the event of failure at least one bright light for other purposes. In fact, the principle then it works perfectly. At least I feel subjectively through the lamp more alert and in a better mood - and that's the main thing. A word to the service of the provider: This is truly outstanding. The light was really perfect packed with plenty of packing material to absorb vibrations and impacts. Nevertheless, it has the supplier managed to overcome these barriers and to smash the lamp in the package. -Only Times Winter Blues! I need a dose of sunlight on my mood! The customer service was very accommodating. Quick made a photo of the corpus delicti by mobile phone and sent to the company, two days later I held the spare in hands. Chapeau!
