The value of the utility wattage label is usually rounded to a certain rated value. Например, if the system wattage is 28 Вт, the utility wattage label may show 30 Вт. This helps the users find the equivalent system for the LED street lights. A 28-watt LED street light can still use a 30-watt system. Even though the wattage is different, it can be seen as tolerance. So the utility wattage label makes it convenient for the repair technicians.
