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 20 square meters or more. It can replace an incandescent bulb of 166 watts or more, or a halogen bulb of 100 watts or more, while maintaining the same level of brightness in the space.
