It is confusing. It would be easier if they just printed H height. Instead I believe you can get the correct aiming with those dimensions because the 53.2 mm dim and 13.3 mm dim will only exist when the H value is set correctly( trigonometry). In other words measure the beam pattern and adjust till you get the 53.2 mm and 13.3 mm values. Once you do the H will be set properly. Unless I'm totally missing something :eh:superdelish said:
