I have been wanting one of these lamps for years but didnt fanxy spending the cash to find out it didn't work or that I'd bought a fake. I shouldn't have worried though as even if it didn't have any benefits it produces such a beautiful light in the evening and during the day it looks like a great feature. I have issues with my mood through the winter months and I have alrwsdy noticed a difference with this light, mornings aren't such a battle to leave my bed when it's dark and dreary outside, I feel happier within myself regardless of what kind of day it is. I have slept better, I still wake through the night like I normally do (habit I guess) however, I have found it is not tiring me as it used to and I find myself waking into a quite pleasant and relaxed mood and have the ease of going back into a deep slumber. There seems to be a different ambience to my room now as well, it's a place of relaxation and calm and tranquil, something that I didn't realise I didnr have until I realised I now have that sense when I walk into my room.
