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, if placed alone, is capable of adequately lighting a small space of approximately 9 sq.m. It can replace an incandescent bulb from 75 to 82 watts or a halogen bulb from 45 to 49 watts, maintaining the same level of brightness in the space.
