What is the control group and variable in this experiment?

I am doing a project on which light bulb lasts longer, one that is 100 watts, and one that is 25 watts. What is the control and variables? :D


Thanks:)|||The variable is the wattage of the lightbulbs. If you word the experiment in the way you have above then there isnt really a control as you are testing one against the other.
