Oh boy, I want one of these. This would absolutely perfect for winter depression (I suspect much better than the "SAD lamps" marketed for this purpose which are bright not even close to this bright). But £889 is a lot of money for a lamp!
I rather like the way it releases concentrated light towards you, as the sun does through a window, but not everyone wants harsh shadows. At the same time, the reflector makes the 20.000 lumens feel like a lot more, as the light doesn't have to illuminate the whole room, just where you're sitting.
Basically a hanging version of the "Brighter" lamp.
