The bulbs recently discovered "by chance" and tried in the office. So far quite happy with it. It is a pleasant bright light. By globe form you will be in direct view Clean little blinded (by the big matt body). The shade is pleasant, too warm for an office almost a bit. Be obtained only for the yet relatively long period, up to the 90% brightness a star deduction. Is this only in areas useful where you want continuous lighting (office, living room ...) and realtiv rarely short times on and off. For example, a toilet, store room, garage not recommended.
