The strings are designed to use bulbs whose voltages sum to equal the supply voltage. So a string that uses 20 bulbs for a 120V power source. Another factor to consider is the current limit of an LED. LED's do not like a lot of current so besides the LED there is also a current limiting resistor in each light.
