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, if installed on its own, is capable of adequately lighting a space of approximately 11 square meters (about the size of a typical room). It can replace an incandescent bulb from 91 to 99 watts or a halogen bulb from 55 to 59 watts, maintaining the same level of brightness in the space.
