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 distorted. This particular bulb, if placed alone, is capable of adequately lighting a space of approximately 13 sq.m. (about the size of a typical room). It can replace an incandescent bulb from 108 to 116 watts or a halogen bulb from 65 to 69 watts, maintaining the same level of brightness in the space.
