This standard provides a methodology for applying existing test methods for program start ballasts to fluorescent dimming ballasts and provides a way to calculate BLE for fluorescent dimming ballasts. NEMA offers this standard to augment and harmonize with the 2014 Department of Energy (DOE) fluorescent ballast regulations. By design@ dimming ballasts are already energy saving@ but this standard would provide the methodology to also calculate new BLE limits for fluorescent dimming ballasts. This standard offers BLE limits for ballasts of common four foot bi-pin lamps@ such as T8 and T5 lamps that are not covered by the most recent Federal rulemaking.
