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, when used alone, is capable of adequately lighting a small space of approximately 10 sq.m. It can replace an incandescent bulb of 83 to 90 watts or a halogen bulb of 50 to 54 watts, maintaining the same level of brightness in the space.
