The color of the bulb simulates that of daylight, making it an ideal choice for offices as it does not cause eye strain, and also for areas where you do not want the colors of objects to be distorted. This particular bulb, when placed alone, is capable of adequately lighting a space of approximately 12 sq.m. (about the size of a typical 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.
