I ordered 10 of these bulbs and am absolutely satisfied, after about 150std. Operating time is not yet failed and unlike bulbs from other manufacturers also recognize not reduced brightness.
4000K is a beautiful, daylight-like white. It is not blue like many cheap products! Since I was very pleasantly surprised! However, it is of course not a warm white - I use this light color only in the hallway and in the kitchen. Here I need an "active" light and no cozy, warm twilight.
Conclusion: Although 2-3 EUR more expensive, but German brand quality!
