Imported brand lamps are relatively much better, generally used for 5000-8000H, and when used for 2000H, the general sterilization ability is still above 90%. If the lamp is not used often, it may only take hundreds of hours in a year or two. In that case, domestic lamps are generally not more than two years, and they are usually replaced after three or four years of import.
