    <P>(2) For each basic model of metal halide lamp ballast selected for testing, a sample of sufficient size, not less than four, shall be selected at random and tested to ensure that:</P>

    <P>(i) Any represented value of estimated energy efficiency calculated as the measured output power to the lamp divided by the measured input power to the ballast (P<E T="52">out</E>/P<E T="52">in</E>), of a basic model is less than or equal to the lower of:</P>
