They are 130v lamps designed for surge protection and elevated voltage regions. Since in many cases 130v lamps are used on 120v, values on both voltages are published.
I don't think it make sense to use 130V incandescents, where the voltage is typically 120V, i think it would be cheaper to buy five "120V/75W" instead of two "130V/100W" and save the nearly 100kWhours of electricity...
