First off, the surprise when unpacking: the part is really huge, roughly the area of a 17 "monitor.
The device looks from the front of fancy, but effective rear ABS and the stand only allows inclination. But for the price OK.
After switching - wow - damn light The humming of ballasts, I could not understand in spite sensitive Oh..
So I have the appliance installed next to me and had a few days in operation.
While it is somehow pleasant when one is so much light, a "feeling of wellness" but has still not want to stop with me for a week. What bothered me personally, due to the gear that you notice a clear flickering out of the corner of my eye. There are 2x36W fluorescent tubes installed which as usual beautiful flicker several years ago in front of him.
After the device has not even begin to compensate for sunlight for me and it flickers I had to return it, despite favorable Blitz offer price.
May seem better at other people, not for me. 3 stars for usable design and solid workmanship, for my subjective feelings may indeed not the manufacturer.
