What is Ballast Factor and Why is That Important?
Ballast Factor (BF) is a measurement that compares the ratio of light output of a lamp or lamps operated by a specific ballast to the light output of the same lamp or lamps operated by a standard reference ballast. The higher the BF is, the higher the wattage running through the ballast. Some applications need a lower BF to conserve energy and reduce light output, while others prefer a higher BF to increase light output. However, a higher BF does decrease the life of the lamp. AC Electronics can adjust BF to meet the customer’s need.
