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 installed alone, is capable of adequately lighting a large space of approximately 15 sq.m. It can replace an incandescent bulb from 125 to 132 watts or a halogen bulb from 75 to 79 watts, maintaining the same level of brightness in the space.
