(a) (b) (2) (ii) Airflow in the room for the testing period must be ≤0.5 meters/second. (iii) Test circuits must be in accordance with the circuit connections specified in Section 6.3 of ANSI C82.6-2015 (R2020). (iv) For ballasts designed to operate lamps rated less than 150 W that have 120 V as an available input voltage, testing must be performed at 120 V. For ballasts designed to operate lamps rated less than 150 W that do not have 120 V as an available voltage, testing must be performed at the highest available input voltage. For ballasts designed to operate lamps rated greater than or equal to 150 W that have 277 V as an available input voltage, testing must be conducted at 277 V. For ballasts designed to operate lamps rated greater than or equal to 150 W that do not have 277 V as an available input voltage, testing must be conducted at the highest available input voltage. (v) Operate dimming ballasts at maximum input power. (vi) Select the metal halide lamp for testing as follows: (A) The metal halide lamp used for testing must meet the specifications of a reference lamp as defined by ANSI C82.9-2016 and the rated values of the corresponding lamp data sheet as specified in ANSI C78.43-2017 (both incorporated by reference; (B) Ballasts designated with ANSI codes corresponding to more than one lamp must be tested with the lamp having the highest nominal lamp wattage as specified in ANSI C78.43-2017 or ANSI C78.44-2016, as applicable. (C) Ballasts designated with ANSI code
