The color of the bulb simulates 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, when used alone, is capable of adequately lighting a small space of approximately 8 square meters. It can replace an incandescent bulb ranging from 66 to 74 watts or a halogen bulb from 40 to 44 watts, maintaining the same level of brightness in the space.
