The color of the bulb simulates that of daylight, making it an ideal choice for offices as it does not cause eye strain, and for areas where you do not want the colors of objects to be altered. This particular bulb, when installed alone, is capable of adequately lighting a space of approximately 12 sq.m. (about the size of a standard room). It can replace an incandescent bulb from 100 to 107 watts or a halogen bulb from 60 to 64 watts, maintaining the same level of brightness in the space.
