Before and after pictures are not good for "light level" comparison, because the automatic exposure re-adjusts, but well documented absence of shadows prior to downgrade and after downgrade and a well articulated presentation can go a long way in challenging claims of equivalency that while watts were reduced, it did so at the cost of cutting corners.
I don't believe that automatic anything would be wise when trying to compare photos. you need reliable calibrated results. probably should have taken a full bracketed set at a set white degree with a set exposure and set iso at a set distance etc so you could compare apples to apples, otherwise the photos are useless.
