Does the size of a CFL change the amount of electricity they use?

    Yes and no.  Power ratings (measured in watts) vary from light bulb to light bulb.  Generally, larger lightbulbs have a higher wattage, meaning they use more electricity than a lower wattage bulb in the same amount of time.  However, there are other factors besides size that contribute to the amount of electricity a lightbulb uses, specifically its shape and the amount of light the bulb produces, measured in lumens.  If one bulb produces more light than another bulb of the same size and shape, it’s likely to also use more electricity.  So, when picking out a CFL bulb, make sure you pay attention not only to the size, but also to the power rating, measured in watts (W), as well as the amount of light it will give off (lumens).
