Abstract:
1. A method for checking correct rotational position of a pole with an array of lighting fixtures, each lighting fixture including an arc tube substantially surrounded by a reflecting surface and a glass lens to produce a controlled, concentrated beam that is generally converging in nature from the fixture along an aiming axis to a pre-aimed aiming point on a field, comprising: a. placing a marking or indicia on a glass lens of one of the fixtures of the array generally along the aiming axis of the fixture; b. viewing the marking or indicia from the aiming point on the field; c. determining if there is any offset between the marking or indicia and other structure along the aiming axis of the fixture behind the glass lens; d. if not, assuming the rotational position of the pole is correct and that aiming of all fixtures in the array is correct; e. if so, rotating the pole and rechecking according to steps a–c.
