easily good design, great light color, a bit too dark, quiet whir,

Absolutely positive:

- Easy (and only marginally larger than the old halogen lamp)
- Design almost like an old bulb
- The light color temperature and is indistinguishable from a conventional incandescent or halogen lamp - other LED lamps work here clearly "artificial"

slightly negative:

- I hear a slight hum when it is absolutely silent. nothing that really bugs in the bathroom, at the desk but potentially disruptive
- The lamp corresponds to a maximum of 50W lamp - is described here with 600 lumens so, on the packaging, however, is the talk of the front "about 60W" on the back, it is then given equivalent to about 48W. which comes out rather.

Conclusion: If looks the future of LED bulbs, I am looking forward. But if you need a really bright lamp, must be patient at ease.
